Event Log

Sep/19     

Operations team: Su Dong , Rob Mina 

Previous dissembled Caladium is reassembled by Test Facility in the ESTB tunnel but parked on the side as beam pipe was reinstalled for a down stream experiment (somewhat of a surprise for us) this week. Caladium mover control electronics is still missing and to be installed next week. We checked the re-connections and found a few errors and missing links which got corrected. Connected the double chip module 94-04-03 as DUT with upgraded DUT CAT6 data cables and tried pixel digital calibration which worked as expected. Reordered the power supplies on the remote power strip to match the original panel in EPICS.     

Sep/20

Checking with Carsten about what is really going on this week, it turned out T-542 (sFlash) is taking the entire period Sep/22-Sep/26 so that the originally agreed Sep/26 for us has evaporated and we were never informed of that change. 

Sep/23

Checked with sFlash at ESA control room. The intense scene confirmed the fear that they will probably need the entire period, including Monday.

Sep/26

sFlash is continuing with their runs so that we are unlikely to have any chance to run for Monday, considering that Caladium still needs to be brought onto beam line after beam pipe removal. So Monday is expected to mainly doing lab test of the first RTI module to get proper configurations prepared and check other preparation items.   

Sep/27

  • 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.
