- 8AM MCC meeting mentioned ESA beam delivery problem for sFlash on Monday but eventually took very good beam data. sFlash cleanup.
- 10AM ESA became permitted access.
- Caladium moved onto beamline after removing section of beampipe and mover electronics box reinstalled. Chiller level low, refilled. DUT stage also back on and hold current is nominally driven. Caladium powered up current anomaly traced to Clock-Jtag cables swapped. Missing TLU-NI USB cable located and reconnected. Caladium auto-trigger run and standard DUT (mounted 93-04-03 IBL double chip module back) both operating.
- Noticed IBL double-chip DUT LV PSU setting sagged from 1.5V->1.2V when module current went up to 0.5A. Realized this was due to the current limit of 0.5A appropriate for single chip modules. Raised current limit to 0.8A stablized voltage through threshold tuning exercise.
- FE65_P2 readout arrived from LBNL. Mike Dunning/Juan Cruz laid two DUT ethernet lines for the two readout PCs to connect to the ESA 104 private subnet. Mike granted fixed IP addresses: 172.27.104.52 (riverhorse) and 172.27.104.53 (inkfish), gateway is 172.27.104.1 and mask 255.255.252.0.
- Various cameras setup - see main portal.
Sep/28
Plan for today:
- Priority is to debug FE65_P2 readout integration with telescope (Timon, Ben) and taking telescope whenever needed,
- Install the 2nd RTI SC module into the ESA DUT seat to do in situ threshold tuning (Sergei,SD).
- Threshold tuning for the first RTI SC module at group C lab (SD,Francesco,Rob,Nicole)
- HV remote control/mon with EPICS (Ben,SD with help from Mike)
- possible telescope geometry optimization (SD)
- Presentation of our plan and beam requirement to MCC (SD) at the 4pm accelerator weekly planning meeting next to the accelerator control room at the ground floor of B52. Everyone is welcome.
- Discuss preparation status, run plan and shift assignment at ESA control room at 5pm.
