Lockup checklist for Hall-C TechnicianLockup checklist for Hall-C Technicians 1. __ Vacuum systems; scattering chamber, downstream beam

line, HMS and SHMS vacuum. 2. __ Remove scattering chamber window-covers and inspect windows. 3. __ Remove pivot railing and block off pivot, place sign. 4. __ Ensure all vacuum gauges and pumps are in good condition,

check oil level and electrical. 5. __ Check LCW system for leaks and valve position. 6. __ Detector gas supply working correct in gas shed, on HMS & SHMS 7. __ Sufficient detector gas is stocked. 8. __ Remove areal platforms and scissor lifts from Hall C. 9. __ Move machine tool platform to the physics storage building. 10. __ Place all craning and rigging equipment in designated areas. 11. __ Move ladders to the truck ramp. 12. __ Remove all trash from the Hall, replace metal trash bins with

plastic trash bins. 13. __ Ensure Hall ventilation in on. 14. __ Confirm with Tim Minga if smoke extraction fans are on auto. 15. __ Lockout upper truck ramp door remote control. 16. __ Remove toolboxes and power tools, leave basic tools sets for

emergency work in the Hall. 17. __ Clean the Hall C floor. 18. __ Check for obstructions around and under the spectrometers. 19. __ Verify that HMS and SHMS rail stops are placed.

Remaining installion as covered under the 12 Gev. Upgrade Status

We aim to complete the list in the following sequence:

Ø The SHMS wire chambers are ready and will be installed before the end of August.Ø The Noble-Gas Cerenkov will be test fitted and removed again in prep for the dipole by Sep.

2nd.Ø Install and connect Current Leads for 2nd Moeller Quad by Sep. 9th. Ø Install and align scattering Chamber by Sep.13th. Ø The Hall C Technician group will assist engineering

installing and testing Q2, Q3 and the dipole.Ø Installation of vacuum spool pieces between magnetsØ During the commissioning of the Dipole the downstream beam line will be installed.

Downstream beam line status

• All medium angle beam line components are here.• The gate valve was cleaned and reassembled but has not been

leak tested. • 2 BPM pipe sections show vacuum leaks and need welding.• Anchors for the support posts are in place.• Assembly will take ~1 week.
