Ordered list of tasks for e14002:

prior to vault access:

1. Test HINP 4 electronics (10/3)
   • Edit spectcl for HINP 4 (Kyle, 10/3)
   • Pulser test MB1 (14 CBs) (Kyle, 10/10)
   • Test HINP 4 (E) motherboard and HINP 3 (dE) together (Kyle)
2. Test CsI shaper/disc (Sean/Kuan)
   • Test 5 pico shaper/disc (16 channels each)
   • Confirm with WU/UCONN if first stage shaper gains need adjustment
3. Alpha Tests of HiRA E's (Kyle/Sean, 10/12)
   • Determine if/which strips are broken
4. Test dE preamp box (e14009)
   • Determine if/which channels are broken
   • Work with WU to integrate ISEG bias
5. Set up HiRA mount (in N2/N3) with dummy detectors (Sean,Kuan)
   • locate missing pieces
6. Test/locate all internal cables with cable tester, remake/fix any lost or broken cables

After access to vault (Nov 1)

1. Test HiRA target ladder
   • Work with Craig Snow to modify if needed
2. Work with facilities to get chamber installed (Finished by Nov 12)
3. Clean chamber and reach functional vacuum (1e-6)
4. Arrange feed-through flanges as desired and retest vacuum (Nov 12)
5. Install internal mounting structure (Nov 14)
   • Maintain isolation of internal parts from the chamber walls, test frequently
6. Assemble the array with HiRA dummies and do rough alignment with transit
   • Dave Sanderson will need to install the transit
7. Install chiller and cooling water lines inside chamber.
   • We can test these are leak tight by first pumping with them empty (water blown out with Nitrogen) and then fill with water and retest vacuum. No HiRA detectors inside chamber until this is complete!
   • Once they have been leak tested these should never be disconnected.
8. locate computer and desk for vault
9. Move electronics racks (3, from hira lab) to S2 vault . Connect to chamber feed-through flanges
   • Retest electrical isolation. The racks must be unplugged from power.
10. Test electronics with pulsers
11. Remove dummies and replace with real telescopes. Align with transit.
12. Setup and test ISEG bias supply
13. test the Si detectors with alpha source
14. test CsI with cosmics
15. Install and align targets
16. Set up the logic.
    • The master trigger will likely be the CsI as last time.
