  1. Experimental Areas – Hardware Tests for 2006 startup Outline SPS North Area Changes since 2004 Commissioning plan / HW tests Where do we stand Future steps – critical items PS East Area AD Experimental hall Ilias Efthymiopoulos – AB/ATB/EA PS-SPS Days - 2006 CERN – January 18, 2006

  2. Changes since 2004 (1/7) SPS North Area Beam Lines • Three experimental halls : EHN1, EHN2 (COMPASS), ECN3 (NA48) • 7 beam lines ; ~1000 equipment installed ; total length > 6 Km • ~1500 users performing experiments and tests ; frequent changes of beam configuration and settings Total no. of requests keeps increasing 30 experiments & tests in 2006 • 80% to be installed in EHN1; the rest in PS East Hall • West Area was dismantled in 2005 • More frequent user changes and beam settings ; sharing of beam time

  3. Changes since 2004 (2/7) EA Renovation Project (SPS Beam Lines) Started 5 years ago, arrives to completion in 2006 Highlights of the project: Hardware renovation • BDI hardware from CAMAC to VME equipment oriented modules • Introduce new hardware (PLCs) to replace custom solutions and promote standardization (i.e. vacuum to AT/VAC standard PLCs) • Migrate the magnet control from the “junction crate” (G64) to VME • Replace obsolete NCD X-terms in BDI and user barracks by PC’s • Upgrades to the access system and timing distribution to new standards Software renovation • Introduce new control software “CESAR project” following the AB/CO standard solutions to replace NODAL • Allow improved user interface and facilities to help operations and maintenance • Use of FESA and PLC software for the front-ends

  4. Changes since 2004 (3/7) EA Renovation Project (SPS Beam Lines) Started 5 years ago, arrives to completion in 2006 For the SPS 2006 startup, all the North Area will be switched to the new system • Following successful tests in 2004 in the West Area and with selected users in the North Area (NA60) What is new: • New HW for the majority of the beam diagnostics instruments to VME modules • The remaining ones are foreseen for later in Summer ‘06 • The front-end software for a large number of equipment is switched to FESA • For the rest, the “gateway” of SL-Equip will be used • All vacuum pumps will be controlled by standard AT/VAC PLCs via PVSS

  5. Changes since 2004 (4/7) BDI hardware renovation: Before: function oriented approach  Now : equipment oriented approach 10 barracks full with electronics completely refurbished in 2005

  6. Changes since 2004 (5/7) …What is new : • The control software will be CESAR ; it includes: • New user GUIs • New databases for layout, parameters and settings files • Use of AB/CO “standard” products for alarms, logging, timing • Possible to run from Linux or Windows PCs • Jython as scripting language • Can be used for the development of expert tools • Link to access system via FESA and special gateway • No HW changes to the access system itself • New timing distribution using CTDV / TG8 • TG3 remains in use for the magnets – will be changed once upgraded to VME control

  7. Changes since 2004 (6/7) In addition: • New shielding in TCC2 for the EHN1 beam lines • To respect the new (lower) radiation limits and in view of the running at higher intensities for M2/COMPASS • Upgrade of M2 beam line to reduce background at the experiment • Possibility to run at higher (20%) intensities • New experimental areas and interlock chains • Required to accommodate the large number of users • Replace an old “manual” dump with a mobile remotely controlled one • Cabling renovation in TCC2

  8. Changes since 2004 (7/7) New shielding in TCC2 : Protect the EHN1 hall from muons produced at the T4,T6 targets Ideal storage of old radioactive blocks!!!

  9. Commissioning Plan (1/2) • Dry Run-1 (10 -11 November 2005)- test two beam lines {H2, H4} • Dry Run-2 (27 – 31 March 2006) – test the whole of the North Area • Dates to be confirmed this week – new dates to better fit work plan • Commissioning with Beam • During week 24 (12-15 June) with extracted beam into the areas • Dates must be fixed to inform users beforehand and prohibit access to the areas

  10. Commissioning Plan (2/2) Goals • Validate proper functioning of all equipments • Validate proper functioning of control system under full load • Was the main worry during the early tests in 2004 • Validate BDI diagnostic tools, required for HW commissioning • Expert tools under development within CESAR project and/or using the FESA equipment navigator • Simulate the commissioning, and operation of the beam lines • Test as much as possible without beam during the Dry Runs • Final test during the commissioning phase with beam • The easy and reliable way to identify cabling or software errors!!

  11. Where do we stand (1/6) Dry Run-1 : 10-11 November 2005 • Used the small “PCR” installed at the AB/CO Pavillion (bat. 936) • Usefulness of the exercise validated and appreciated by everybody • Tight deadline but a serious effort was put to meet that milestone • As an example, it allowed to identify early enough a “forgotten” piece of software • A working system was provided in both Windows & Linux • All available HW and software parts were integrated • About 15 people actively participated during the two days of the event from several AB groups: OP, CO, PO, BDI, ATB,… • Positive feedback was received for the CESAR GUIs and the implemented functionalities • Requests for improvements and corrections collected, most of them will be implemented for the Dry Run-2

  12. Where do we stand (2/6) CESAR GUI window:

  13. Where do we stand (3/6) … Dry Run-1 : 10-11 November 2005 • No slow-down in performance was observed • Tests made to simulate realistic load conditions • Good performance thanks to the move to FESA-2 and improvements inside CESAR On the negative side: • Handing of exceptions coming from CMW and Equipment must be improved • It was the origin of the only “freeze” of the system • The problem is now understood and fixed - will be tested again in Dry Run-2 • Due to the missing software part the test of the access system was not possible • Although the HW was available on time • One of the major tests for Dry Run-2

  14. Where do we stand (4/6) Dry Run-1 – Summary The basic components of the beam lines were successfully tested and work • Magnets, collimators, beam profile counters • Thanks to an effort put to recompile and restart NODAL on the latest Linux version which allowed to use the SL-Equip and Equip-bus software to run • BDI equipment on new hardware and FESA • Beam counters ; filament scanners ; particle counters • Upgraded equipment on PLC and FESA • In/Out motorized equipment • Vacuum control using AT/VAC PVSS standard and readout in CESAR • Control system functionalities • Beam file handling ; beam tuning programs (“scan”); element navigators; information display

  15. Where do we stand (5/6) Dry Run-2 : What will be tested • Originally foreseen for middle of February – moved to end of March to allow testing a larger number of components • We would like to do it from the newly inaugurated CCC !!! • The Access system {access doors, safety chains} • Including the LOKN logic which defines de basic safety conditions for the NA beams • The timing distribution – for Dry Run-1 some events were simulated • The remaining BDI renovated equipment • Particle Identification devices {calorimeter, Cherenkov counter, delay wire chambers} • Additional functionality in the CESAR control software • GUI for scrapers, fixed collimators, SEM readout and target control • Protocol to send data and information to the experiments • Login and security mechanism for the users • Jython interface for online scripting language • First test of the prototype for the new magnet control via VME • Get an estimate of possible switchover later in the year Significant amount of work involved – but can (should) be done Mid-way towards the startup – gives time to correct things in case of problems

  16. Where do we stand (6/6) Beam startup or later : What remains to be tested • Installation and configuration of the PCs in the user barracks • Magnet control • Delestage – if considered useful (most likely not!) • Control of the large spectrometers for the experiments • Degauss GUI before loading new settings • CEDAR counters for particle ID • Requested by NA48/3 and ATLAS • Utilities for the operations within CESAR • Info publishing on the fixed displays ; alarms (using LASER) • Readout of radiation monitors • Surveillance programs for the target (wobbline) or the beam line (P0 survey) • Logging and browsing and use of a QUERY tool • Browsing and update tools for the configuration database

  17. Critical Issues • Expert Diagnostic tools • Parts exist; should get used to new environment having to combine information from different sources: CESAR GUIs, FESA navigator, … • Maintenance and support for non renovated equipment • Some critical ones like collimators still on SL-Equip • Can be accessed directly from CESAR using CMW gateway but not with FESA • Support for NODAL software still needed for some expert applications • Control and readout of CEDAR counters on critical path • Requested by NA48/3 and ATLAS • Possibility to satisfy the request but in “non standard” way • Operation • Adopt to the new CCC environment

  18. PS EAST Area • No modifications since 2004 • Modifications to primary zone discussed elsewhere (T.Zickler’s talk) • Problem with dipole in T9 limiting the beam energy to 10 GeV (instead of nominal 15) still to be investigated and probably fixed?? • Must experience the new “remote” operation • Renovation project to follow that of North Area • New hardware for beam instrumentation • Move to “CESAR like” environment

  19. AD Experimental Hall • The ATHENA collaboration does not exist any more and the zone is from this year taken over by ALPHA who will continue physics working on a second generation trap. • The beamlines still have the old MWPC:s which are destructive and slow. • The non-destructive pickups that were needed in view of operating from CCC have not been built

  20. Summary • A first HW test of two beam lines (H2 and H4) – Dry Run-1 - was successfully realized in November 2005 • All the available (at that time) HW and SW was tested under realistic conditions and valuable feedback to was given to the developers. • The next milestone is Dry Run-2 scheduled for end March 2006 • Test the whole North Area beam lines • Almost complete test of all equipment and functionalities • First test of new magnet control under VME • Due to the large number of HW changes, the long shutdown, and the reduced resources available, the “Wet Run”(i.e. Commissioning with beam) before the Physics starts is mandatory • No show-stoppers identified so far but still lot of work ahead!!! Many thanks to all participants for their continuous efforts
