- 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 esadutlbnl1 (riverhorse) and 172.27.104.53 esadutlbnl2 (inkfish), gateway is 172.27.104.1 and mask 255.255.252.0.
- Various cameras setup - see main portal.

- 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.
Activities:
- RTISC2B replaced the 93-04-03 as the RCE DUT to get threshold tuning going for it.
- When attempting to move the DUT closer to beamline we finally realized the oddity of the vertical position was due to the DUT stage mounted upside down. Juan corrected the mounting and now position close to be central.
- Sergei installed a script duplicate.sh in the moduleconfig directory on esadutdaq1 so that one clone an existing module's RCE DUT config directory into a new module's starting configuration with underlying sud-directory file name to follow the new module name.
- The Research Yard construction people are unhappy about us rushing across the area in speed so that we are currently disallowed to go to ESA from the Research Yard ground floor through Gate 17/SSRL route. Everyone should go to ESA from Gate 30 to the top level counting room then down the stairs to ESA hall. If we have to drive in with equipment, we can give Keith Jobe a notice to arrange the passage via Research Yard
