HiRA Wiki

Ordered list of tasks for e14002:

prior to vault access:

1. Test HINP 4 electronics (10/3)
   • Test HINP 4 (E) motherboard and HINP 3 (dE) together (Kyle, 10/31)
2. Test CsI shaper/disc (Sean/Kuan)
   • Test 5 pico shaper/disc (16 channels each)
3. Test dE preamp box (e14009, UCONN)
   • Determine if/which channels are broken
   • Work with WU to integrate ISEG bias

After access to vault (Nov 1)

1. Test HiRA target ladder
   • Work with Craig Snow to modify if needed
2. Clean chamber and reach functional vacuum (1e-6)
3. Install internal mounting structure (Nov 14)
   • Maintain isolation of internal parts from the chamber walls, test frequently
4. Assemble the array with HiRA dummies and do rough alignment with transit
   • Dave Sanderson will need to install the transit
5. 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.
6. Test electronics with pulsers
7. Remove dummies and replace with real telescopes. Align with transit.
8. Setup and test ISEG bias supply
9. test the Si detectors with alpha source
10. test CsI with cosmics
11. Install and align targets
12. Set up the logic.
    • The master trigger will likely be the CsI as last time.
