- ePixM June 15th Beamtime Prep:
- Pre-setup meeting
- Setup deployed on Wednesday in MFX at beam dump location
- We can talk to the detector, LCLS dac works fine.
- will move the setup to the final position on Saturday, before the beamtime.
- Wave8 diodes need to be installed before the beamtime as well
- Detector Mask design
- Five mask designs ordered
- status
- Black kapton need to be stuck to the surface of mask
- Measurement plan and staffing
- Set to 110V
- set switching point low (say 5keV), and look for 1,2, and 3 photon peaks in Low gain . Compare this linearity against the ADU vs wave8 linearity. Compare latter against same for switching point at 25keV. Are they the same?
For each intensity scan, make sure to have sufficient granularity in intensity, and get more statistics (take several intensity scans in a row). - mask sections of the detector. Investigate power sag effect in hi gain. Intensity scan (change intensity order to look at temp issues).
- 6x intensity scans per mask (intensity: HI→LO, LO→HI, Stagger, 2x each)
- Charge injection before or after shift if possible.
- Stuff to do:
- mini-X tests in marrietta
