  1. SR1 extension follow up 26-Feb-18 Marco Ciapetti

  2. Introduction • Various updates • Reinforcement of the ceiling • Current status of the project • Updated schedule

  3. Various updates • On 15/02/2018 the combined VIC for ECOFRED and ARCECLIMA was done • During the VIC it was requested (by both firms) to re-open the wall panel of the extension in order to ease the passage of the material  done on 22/02/2018 • TC added a “plastic-strip door” in order to limit the rain entering in the cleanroom • ECOFRED (internal envelope) and ARCECLIMA (EN-CV) started on 19/02/2018 • ECOFRED is going very fast: the removal of the ceiling (foreseen to last 15 days) is already finished  access to the ceiling is no longer possible • Due to this anticipation, ECOFRED proposed an updated schedule that was checked and approved by both EN-CV and TC (see updated coordination schedule)

  4. Various updates • ARCECLIMA is working on the installation of the vertical ducts along the wall and the installation of roof supports for horizontal ducts in the extension • ARCECLIMA discovered lately that the foreseen structure for the CV ducts running along the ceiling of the existing portion was underestimated. They are working on a new proposal that will be evaluated by TC • Thierry needs to know if there will be cameras in SR1 cleanroom. If yes, how many? Where?  Kendall reply that this info will come later on

  5. Plastic duct for access control cables ECOFRED requested to remove/displace the plastic ducts running along the wall between cleanroom and radiation lab, because it will conflict with the new ceiling panels TC has contacted the Access control group (Nino Rama), to study an alternative path Waiting for a reply

  6. Reinforcement of the ceiling • BEJEAN confirmed they will perform the intervention in week 11 (12-16/03/2018) • TC is still waiting for technical documentation from BEJEAN. This should be sent before the end of February • The VIC for BEJEAN has been set on 05/03/2018 at 10:00 • During the intervention, it will not be possible to access the radiation lab • TC is in contact with SMB (Raul) to get the green light from a structural point of view (08/02/2017)  On 22/02 they were still working on it  Waiting for reply

  7. Reinforcement of the ceiling proposal

  8. Updated Schedule • Jun 2017: SMB started civil engineering works • Jul 2017: SMB prepare the foundations • Aug 2017: SMB install the concrete slab and the ramp • Sep 2017: SMB started the installation of the mechanical steel structure • Oct 2017: SMB completed the steel structure, the external walls and the roof. EN-CV installed the temporary AHU and ducts. EN-HE-HM started the installation of the rails • Nov 2017: SMB removed the internal wall of the current cleanroom and started the road works. EN-HE-HM completed the installation of the rails. EN-CV started removing the existing components • Dec 2017: target for ending SMB works. EN-CV removed the existing components • Jan 2018: EN-EL install lights over the internal ceiling and remove cables over the ceiling • Feb 2018: EN-CV and TC started working on the HVAC system and internal clean room installation  in progress • Mar 2018: EN-CV and TC will continue working on their WPs. • Apr 2018: EN-EL, IT-CS should also start installation. Target for ending clean room extension installation • May 2018: EN-CV should complete the commissioning. IT-CS and BE-ICS should complete their commissioning • Jun 2018: Installation of cables from user side • Jul 2018: target for commissioning the SR1 clean room extension

  9. Current status of the project • ECOFRED protected the test area using material from the temporary protection wall. They also dismounted the entire existing ceiling and mounted the enclosure around pillars. Now they are installing the supports for new ceiling panels • ARCECLIMA is currently working on the installation of vertical ducts • SMB Work Package is almost completed. Only exceptions are: • Painting on the road (parking places, etc.)  to be done after the YETS • Antistatic floor  to be done once ECOFRED will complete the installation • Modification of emergency doors

  10. BACK UP SLIDES

  11. SR1 cleanroom extension – WBS (Work Breakdown Structure)

  12. SR1 cleanroom extension – OBS (Organizational Breakdown Structure) • Project board: Ludovico Pontecorvo (163664) – ATLAS Technical Coordinator Siegfried Wenig (163865) – ATLAS ExGlimos Marco Ciapetti (169451) – Project Manager • Safety: Valentin Algoet (167993) –HSE-SEE representative John Robert Etheridge (164647) – P1 Safety Coordinator • WP1: Civil Engineering (SMB-SE)  Pierre Cardon (167840) • WP2: Cooling and Ventilation (EN-CV)  Alexandre Joel Broche (166078) • WP3: Electrical Installations (EN-EL)  Thierry Charvet (162352) • WP4: Cleanroom Internal Envelope (EP-ADO)  Marco Ciapetti (169451) • WP5: IT (IT-CS)  Leszek Borakiewicz (169195) • WP6: Fire Detection (BE-ICS)  Denis Raffourt (163219) • WP7: Rails (EN-HE-HM)  Roberto Rinaldesi (166379) • Users: Kendall Reeves (162808) on behalf of ATLAS ITkDidier Ferrere (160515) on behalf of ATLAS IBL

  13. SR1 cleanroom extension – PBS (Product Breakdown Structure)

  14. Safety coordinator John Robert Etheridge John.Etheridge@cern.ch (164647) is the safety coordinator of P1. He will help TC to ensure that all the works will be done according to the CERN safety rules. For all WPs, a VIC shall be prepared after the design phase and presented by the responsible of each WP to the safety coordinator beforestarting the works. John is invited to this follow-up meeting so that he can be informed about on-going activities and can control that all foreseen/incoming activities are properly planned from the safety point of view.

  15. Power consumption • The Users are planning to test in the SR1 cleanroom 1/8 of the entire ITk services • On 28/11/2017 TC had a meeting together with the Users (Dave, Susanne, Kendall) and EN-EL (Thierry) trying to better understand the situation. The results of the meeting are listed below: • For the moment it is not yet known the amount of power that will be required: • PP2s are not yet designed • An additional chiller will be required, but still not defined • In SR1 there are: • one (existing) switchboard (EBD5/1R) of 630 kVA (≈580 kW and 910 A) serving the racks area and the HVAC. The measures done show that between 12/2013 and 06/2017 the average served current was 180 A, with peak values around 360 A. This switchboard has several spare circuits that can be used. If the new HVAC system will have the same power consumption of the actual one (230 kW), there should be at least 350 kW available • one (new) switchboard of 250 A serving the cleanroom power outlets

  16. Doors for emergency exits • In order to maximize the external view and natural lighting, TC requires the fully transparent doors for the emergency exits  SMB has to change doors • As specified during the design phase and again in the email sent on 12/10/2017, the door of the emergency exit shall: • Have a panic bar (push bar) inside to easily open the door in case of emergency • NOT have the outside handle: the door must be used only in case of emergency  and shall not be opened from outside (the lock shall be removed) • Be airtight (at least class 3 according to EN-12207) and compliant with the Swiss law

  17. CV balance sheet for power dissipation Updated on 15/08/2017

  18. Safety lights proposal Existing safety lights Additional safety lights proposed by TC ACCEPTED Approved by HSE

  19. Problem with double door on partitioning wall OLD ACCEPTED The previous version of the double door was in front of a fixed structure. It has been accepted to move it in between the two windows even if it will be facing a pillar

  20. Position of lights switches in SR1 cleanroom ACCEPTED

  21. Lights switches Each spot ( ) will contain one two-button switch Each switch should be embedded in the wall and as much as possible airtight. ECOFRED suggested that the switches shall have an International Protection Marking at least IP54. EN-EL proposes to install the following type: ACCEPTED The basic idea is: One button turns on/off all the lights in the extension and the second button turns on/off all the lights in the existing portion

  22. Position of power sockets in SR1 cleanroom ACCEPTED

  23. Power sockets As already agreed, each spot ( ) will contain: • 4x 220V - 16A (CH standard) • 1x 400V - 32A Local differential switch will be installed on the new switchboard Each sockets should be embedded in the wall and as much as possible airtight. ECOFRED suggested that the power sockets shall have an International Protection Marking at least IP54. EN-EL proposes to install the following type: ACCEPTED

  24. Position of Ethernet sockets in SR1 cleanroom ACCEPTED Single socket Double socket

  25. Ethernet sockets Each spot ( ) will contain one double socket and each spot ( ) one single socket Each Ethernet socket should be embedded in the wall and as much as possible airtight. ECOFRED suggested that the Ethernet sockets shall have an International Protection Marking at least IP54. IT-CS proposes to install the following type: ACCEPTED

  26. Sockets plate It has been agreed to add all the sockets (Electrical and IT) on a custom plate. This will allow to have one single hole in the wall/enclosure for each spot. The custom plate has been designed by EN-EL and TC and accepted by IT and the users. The agreed height of the plate from the floor is 500mm (center). The revised version is shown below. Dimensions will be confirmed ASAP. ACCEPTED

  27. Lighting • The current lighting level in the actual cleanroom is 400 lx. • Due to the absence of external windows and natural lighting the Swiss law requires as compensatory measure to have at least 600 lx, with a C.R.I. ≥ 90 and a color temperature between 5300 K and 6500 K • Users (Danilo) requested a lighting level of at least 1000 lx (see email on 20/10/2017). • ECOFRED will provide the following lighting system: • LED lighting units with a C.R.I. = 90 and a color temperature of 6500 K • Lighting level of at least 1000 lx at the working place with a Uniformity Ratio of 0,7 ACCEPTED

  28. Taken decisions ACCEPTED On 14/11/2017 HSE gave the green light for the layout of the parking places shown in the picture above

  29. Proposal 3 for CV inlet duct encapsulation No encapsulation Encapsulation V3 ACCEPTED • Only the duct, the small pillar and the central cross of the metallic structure are encapsulated • The opening for grounding proposed by EN-EL must be displaced by 150mm • Worse for cleanliness point of view (inclined surfaces can collect the dust) • Smaller surface lost in the cleanroom: 1.33 m2on the floor and 2.77 m2 from 2.3m from the floor

  30. Cable trays and enclosures ACCEPTED

  31. Antistatic floor of the extension • SMB proposed the following flooring solution: • A first layer (primer) made of: Sikafloor 161 • A middle layer (with antistatic properties): Sikafloor 220 W Conductive (RG: 103≤ R ≤ 104Ω) • An upper layer (protective and ESD): Sikafloor 262 AS N (RG≤ 106Ω) • According to Sylvain, the proposed solution is more than enough for the purposes of the cleanroom. • Users agreed to this proposal (see email from Kendall on 10/09/2017) • SMB can proceed with this solution ACCEPTED

  32. New proposal for CV inlet duct ACCEPTED The blue duct now is not crossing anymore the room over the ceiling, but below the floor The big mobile sink has been temporarily disconnected and displaced The position of the lighting units must be updated Two proposals for the encapsulation of the ducts (see next slides)

  33. Position of the permanent fan coils for R-C04-A Left Right ACCEPTED • EN-CV will dismount the current grills (when possible/useful). • The two proposed locations for the fan coils of the permanent AHU in the test room are shown in the above pictures. • They have been approved by Kendall on 16/08/2017 and by Didier on 21/08/2017. Dimensions of each unit: Width: 1600mm Height: 700mm Depth: 300mm This will be removed by EN-CV To be displaced by the users To be displaced by the users

  34. Temporary AHU in R-C04-A • This temporary AHU will be placed outside SR1 (back side) to supply fresh air (hot and cold) in the test room (R-C04-A). The unit will be in use from November 2017 to June 2018. More details and information about the TSH060 unit can be found here

  35. Electrical matters • Current 160A switchboard will be replaced by a 250A switchboard (maximum possible considering actual electrical consumption, future general needs and current transformer capacity). • The order for the new switchboard has been sent on 07/07/2017. Total cost is ≈35kCHF • According to Thierry calculations (see email of 30/06/0217) a maximum of six 380V-32A sockets can be used simultaneously in exceptional cases: • 4 devices running on 380V-32A sockets can work at the same time with no constraints • It should be possible to add 2 more temporary • Grounding works are completed

  36. Schedule for ITk Pixel tests in SR1 • April-August 2017: test of prototype with one full cooling line ~375 W in SR1 (August 2017) • September 2017: commissioning of system setup in SR1 (power needed, few days of outage can be discussed, CO2 partially needed for commissioning) • October-November 2017: assembly of prototype in SR1 (power and CO2 needed, days of outage can be discussed) • November 2017-November 2018: systematic evaluation of demonstrator in SR1, dedicated test bench for comparison of DAQ, readouts, powering, cooling (power and CO2 needed). Short periods of outage can be discussed: a possible solution is to run power extension cables from the nearest building, if needed(tbc)

  37. Schedule for ITkStrips tests in SR1 • April-September 2017: Testing of pre and post irradiated modules in SR1 + Testing cold (-35°C) with chiller • September-December 2017: assembly of parts for system test setup for a Strip Stave in SR1 • January-November 2018: Commissioning of system tests of a stave (CO2 cooling, interlock, DCS, DAQ, cabling) As agreed with Susanne and Jens, short periods of outage can be discussed

  38. Taken decisions • Services cannot arrive from below the fake floor into the pillars: pillars do not go through the fake floor, but they are loading the concrete floor. Openings are present in the concrete floor, but far away from the pillars. • The only possible solution is to run the cables over the ceiling and enter from there into the enclosures. • Cable trays and enclosures shall not cross the rails in order not to lower the ceiling in the assembly region. • The users required to have a minimum height of the ceiling of 3.7 m • The option of lowering the current ceiling (panels are 4.15m high) has been discarded

  39. Taken decisions • The clean room will be ISO 8 according to ISO 14644-1 • All cable trays shall be covered • WP3 (EN/EL) will take care of all the cable trays related to main electrical services, while WP4 (TC) will take care of the cable trays for electrical controls. Users shall specify their needs ASAP • ESD precaution will be obtained with mats, people grounding and NO new antistatic floor is foreseen in the radiation lab • The SR1 radiation lab can be used by ITk tasks, but needs to be cleared with 1-2 months notice in case of TC/detector needs during EYETS

  40. Taken decisions • 13 power boxes will be installed by EN/EL. One power box at each of the 4 pillars between existing room and extension (the central pillar will be removed) and one power box every 3-4 m on the wall (evenly distributed). Each power box shall have at least: • 4x 220V - 16A (CH standard) • 1x 400V - 32A • Local differential switch for each sockets group (one for 4 sockets 230V-16A  and one for socket 400V-32A) • 2 existing sockets boxes will be kept on UPS network (in the pillars area). No additional sockets on UPS network are required • Existing UPS network details: 100kVA lasting approx10 minutes at 80kW (see email from Thierry sent on 28/06/2017) • LED Lighting providing ≈1000 lux

  41. Taken decisions • EN-CV will switch off the air conditioning and ventilation for at least 6 months (schedule should meet SMB’s one) • EN-EL will switch off the electricity for small periods of time (schedule should meet global schedule and users’ schedule) • Overpressure targets: • Overpressure of extended clean room (R-C04-B) is ≥15 Pa • Overpressure of radiation lab (R-C14) is ≥15 Pa • No overpressure in the test zone (R-C04-A), changing room (R-202), other areas • Overpressures of R-C04-B and R-C14 can be manually regulated in order to create slight overpressure of the clean room over the radiation lab if needed

  42. Taken decisions The proposal of extending the changing room R-202 by ≈1m has been accepted. The drawings have been modified Will be removed before starting To be removed To be removed ≈1 m

  43. Cooling and Ventilation stop • The stop of CV system for at least 6 month announced by EN-CV and due to the replacement of the AHU and upgrade of the CV system will cause major problems in the ID test area • Didier, Anatoli and Dave agree that during such a long stop of the air conditioning, the test cannot be performed • A solution has been discussed among Didier, Alex and myself. It has been presented to all involved people and it has been agreed (see next slide)

  44. Temporary solution for R-C04-A during CV stop The main points which have been agreed from both parties are listed below: EN-CV will switch off at first only the portion of the system close to the demolished wall (where they have to work), keeping on the system on the other side of the cleanroom (test area and radiation lab). This will lower at the minimum the amount of time people working in SR1 are affected from the CV stop. To grant fresh air (especially when the R-C04-A will be divided from R-C04-B), the upper door above the emergency door of R-C04-A can be kept open (see attached file). Being an internal building (building into a building), the SR1 cleanroom should not have huge problems regarding the temperature. Especially in winter time and considering the power dissipated into the test area, the temperature should not drop drastically. Anyway, just to be sure to have always acceptable working conditions, one or two mobile inverter air conditioner can be provided (the cost estimate is roughly around 3-4 kCHF each) so that also people in the radiation lab can adjust the temperature in their working area. Alexandre will add these points (even if they are related to a temporary solution) into the “Upgrade of SR1 clean room” document prepared by him and circulated for approval.

  45. External windows requirement from HSE • The building extension is not compliant with the Swiss law, due to the absence of external views and natural lighting • HSE required to TC a formal approval process • On 11/10/2017 TC sent to HSE the Users’ motivation to justify the absence of external window and natural lighting. The motivation is the following: While assembling the ITk, we will be working with glues and epoxies that will require very stable conditions with respect to temperature and humidity.  Windows allowing light to enter will make that more difficult to manage.  Also, we will want to test detector components multiple times during the assembly process, but their performance is temperature dependent.  Having a local change in temperature of one or two degrees will alter detector performances in an observable way, which complicates performance comparisons.  Our objective of building the best, most reliable detector possible demands a high level of stability and control of the environment in which we build it. • TC and HSE prepared the document for the approval process. The document was circulated on 30/10/2017. On 02/11/2017 TC received the green light to proceed from HSE. The approved derogation can be found here on EDMS.
