Detector testing
- EHAT:PMT5, 50V, ramps up, 0.08uA readback. LED cable now connected with new connector. Works. Using driver channel 5. ~250pC at 70%.
Detector installation
- Installed spare PMT (previous ELBT:PMT1A) at window on gun. Connected cables for ELBD:PMT0 because that set had LED cable.
- Place mic stand on EAST side in low energy section for ELBT:PMT1B installation. Connected all cables. All labeled correctly.
- Note, LED cable label for PMT1C is EACB:LED.
- Found that cable on the roof labeled EABT:PMT1:SIG is actually ELBD:PMT0:LED. Will connect this to channel 8 in driver. Getting 225pC at 45%. Also tested with LED driver channel 8.
- CHANGE OF PLAN:
- Using PMT0 as the diagnostics detector after all with pmt0 cables. sig, hv, channel 4 and led ch8.
- using former pmt1a is now pmt1b, NM 4289. with pmt1b cables.
LED labels
- Connected EACB:PMT1:LED to LED driver channel 2 on roof. Cable will be used for to ELBT:PMT1C detector in hall. Present label is EACB:PMT1:LED.
- Found that cable on the roof labeled EABT:PMT1:SIG is actually ELBD:PMT0:LED. Will connect this to channel 8 in driver.
