  1. 10 m 0 5 m OVERVIEW:UCN Facility in Meson Hall 40 deflection: 145 mr 18.5 12 mr

  2. SHIELDING (Schematic Layout)

  3. SHIELDING CFI cost estimate  schematic layout, based on A.Trudel’s calc.s  $1820 K  Include stacking details of blocks (20% contingency) Latest cost estimate Based on vendor quotes  $2111 K Possible Cost savings  Dose in Skyshine direction can be higher (-1m from top) Existing Concrete (10%, $125K), Special Shielding Blocks (detailed layout, graphite?,…) “New” Steel Blocks (plate thickness) Shielding Quotes: Concrete $1251 k Steel (radioactive) $ 360 k (66%) Steel (new) $ 480 k (33%) • calculations by Anne Trudel: 40 mA, 500 MeV protons stopping in tungsten tgt • assumes 0.5 m empty space around target (no moderator) • figure shows shielding needed to reduce dose to 3 mSv/hr outside shielding • integrating shielding gives 125 m3 steel and 375 m3 concrete not allowing for practicalities of stacking the blocks.

  5. UCN Status: Update • Main Focus of Recent Activities: •  UCN Beamline design & cost estimates • Layout Installation Schedule with Vijay Verma • UCN Beamline design & cost estimates (progress summary): • Shielding  working on 2nd Iteration design and cost • Spallation Target & Remote Handling • Beamline Magnets & Power Supplies • Beamline Infrastructure • Cryogenics • Schedule (progress summary): • Proposed Installation Schedule from Vijay Verma

  7. OVERVIEW:UCN Facility in Meson Hall (Note: New/updated drawing in ~ 2 weeks) 10 m 0 5 m 40 deflection: 145 mr 18.5 12 mr

  8. SHIELDING 1st Iteration  “schematic” shielding layout; cost estimate  $1820 K 2nd Iteration  more refined; based on A.Trudel’s calculations  Include stacking details of blocks; other possible cost savings  New layout (~ 2 weeks) & recosting in progress (S.Austen/C.Davis) • calculations by Anne Trudel, assuming 40 mA, 500 MeV protons stopping in tungsten target • assumes 0.5 m empty space around target (no moderator) • figure shows shielding needed to reduce dose to 3 mSv/hr outside shielding • integrating shielding gives 125 m3 steel and 375 m3 concrete not allowing for practicalities of stacking the blocks.

  9. Spallation Target • Remote Handling & Transportation Issues of concern (P.Bricault) • New calculations from Safety (A.Trudel) indicates target activity level after 10 years of irradiation will still be a factor of ~5 below the A2 transport limit • Present Spallation Target conceptual design  Tungsten Cylinder, 30 mm (D) x 120 mm (L) Target Geom. Optimization (MCNPX code): Troy Dawson (U.W. grad student)  Cooling System: High Pressure He OR Water Discussions w/ P.Bricault, Y.Masuda, G.Clark & others  leaning towards Water • Discussion of conceptual design for Remote-Handling System (P.Bricault) • New Engineer being hired for Target/RH design (?)  Costing…(P.Bricault)  A stopping target of tungsten bombarded with 100 uA of 500 MeV protons.  Blue arrows correspond to 1, 5 & 10 years of irradiation.  Shown below the arrow is the total activity as a fraction of the A2 transport limit.  The inventory of activity in the target at ten years is at approximately one fifth of the A2 transport limit for Type A packages.

  11. Preliminary Coil Design for UCN Kicker Kicker Specs: Kicker Power Supply • 500 MeV protons (p = 1090 MeV/c) • 15 mr maximum deflection (Bdl = 0.0545 Tm); normal deflection 12mr • effective length 1.5 m (physical available 2 m) • aperture 100 mm x 100 mm (possibly 130 mm horiz) • field uniform to 5% over central 80 mm diameter region • flat top 1 ms, flat to 5% over the 1 ms • fires every 3 ms (330 Hz rep. rate, able to run cont.) • can be re-configured (in <1 hr) to run as low as 100 Hz rep rate • power supply able to be located 10 m away

  12. Beamline Infrastructure Beampipe & Hardware, Vacuum, Diagnostics, Controls, Safety, Services Cost Estimate  Discussions with A.Hurst & others  Relevant documents forwarded to Andy for review  Identify missing components in existing Resource Chart  Provide updated cost estimate for BL infrastructure Power Budget/Capacity  Discussions with F.Mammarella  Capacity of substation transf  Does not look like it should be a problem ( M11+M13  UCN )  Revisit after magnet P.S. details clarified  “New” load from He Liquifier needs to be included Cryogenics TRIUMF LHe capacity in 5YP  Enough to meet UCN requirements? Discussions with I.Sekatchev  UCN requirements can be met (and then some)  Igor’s proposed liquifier has enough capacity to service UCN as well as other Meson Hall expts (UCN requires ~1000 L.L./day) (Linde L140 can provide ~ 3300 L.L./day) Cost Estimates  Liquifier costs  5YP  UCN-incurred costs - He Transfer Lines - dependent on Liquifier siting/location (Chuck, Igor, Stu)

  13. Installation Schedule Vijay’s Proposed Installation Schedule for UCN (refining timetable & manpower) 2011 2012 2013 2014 Shutdown Shutdown Shutdown Task 1 Task 1 Task 2,3,4 Task 5,6 Task 7 Task 7 Task • 1* Remove M11 “cold” end (3 wk) Jan 2011 shutdown or Sep 2011 • 2 Remove M11-Q1, Q2, B1, (3 wk) Jan 2012 shutdown • & blank off M11 septum • 3 Remove M13-Q1 to Q7 (6 wk) • 4* Remove PIENU (4 wk) • 5 Take out 1BVB2 (1 wk) Jan 2013 shutdown • Remove balance of 1B and PIF (3 wk) • Install Kicker, Septum, 1UB1, 1UQ1-Q2, (5 mo) • & restore shielding to allow 1A running • 6* Install PIF in new location (6 wk) • 7* Install 1UB2, Spallation Target, Shielding, (4 mo) Partially Jul-Dec 2012 (whenever possible) • & UCN equipment and finish between Jul 2013 – Apr 2014 • * No shutdown required

  14. Installation Schedule & Manpower Requirements UCN INSTALLATION TASKS (Based on Vijay's and Des Ramsay’s notes of the 20 Nov 2009 meeting) TASK Remove M11 cold end. No shutdown required. 3 weeks. 3 Techs + crane and riggers + some support from other groups Remove M11 (Q1,Q2,B1,blank off Septum) Meson Hall shutdown only. 3 weeks. 3 Techs + remote handling + crane and riggers + support from other groups Remove M13 (Q1 to Q7) Meson Hall shutdown only. 6 weeks. 3 Techs + crane and riggers + some support from other groups Remove PIENU No shutdown required. Can be done anytime once PIENU finished. 4 weeks. 3 Techs + crane and riggers + some support from other groups Take out 1BVB2. Kicker will go here. 1BVB2 will also be used on UCN.  Requires Cyclotron shutdown (vault access) 1 week. 3 Techs + crane and riggers + some support from other groups Remove balance of beamline 1B and PIF  Requires Cyclotron shutdown (at least for upstream 1B). 3 weeks. 3 Techs + crane and riggers + some support from other groups Install Kicker, Septum, 1UB1, 1UQ1, 1UQ2, and restore enough shielding to run Meson Hall. To make room for the shielding, may be necessary to leave 1UQ1 and/or 1UQ2 out temporarily  Requires vault and meson hall access. 5 months. 4 Techs, crane and riggers, support from other groups Install 1UQ1 and 1UQ2 if not installed during the long shutdown.  Requires meson hall shutdown only. 4 weeks. 3 Techs + crane and riggers + some support from other groups Install PIF in new location. No shutdown required. 6 weeks. 3 Techs + crane and riggers + some support from other groups Install 1UB2, spallation target, shielding, UCN equipment.  No shutdown required. 4 months. 3 Techs + crane and riggers + some support from other groups In addition, 6 months or so of prep work will have to be done refurbishing magnets, installing water headers on magnets, preparing vacuum boxes and stands,etc. I guess this would tie up mostly beamlines techs. Total “Shutdown” Time(s): Cyclotron shutdown 5.5 months At least meson hall shutdown 3 months No shutdown required 6.5 months

  24. Kicker Power Supply

  25. Kicker Power Supply Ramp-Up: + - SW1 and SW2 are closed, magnet ramps up from the high voltage

  26. Kicker Power Supply End of Ramp-Up: + - SW1 is opened. Current circulates through D3, D1, and SW2

  27. Kicker Power Supply Flat Top: + - + - SW3 closes as required to maintain the flattop with the low voltage supply

  28. Kicker Power Supply Ramp-Down: + - All switches open. Current is against the HV for fast ramp down. Stops at I=0 when diodes become back biased.
