Verify Nominal Operating Voltages and Currents
...
Environmental
Test conditions:
- Detector running and stabilized for two hours, nominal settings.
- Beam monitor shows ~0.75mJ.
Record thermometer and humidity sensor readings:

Airbox T 39.64C Airbox Humidity 0.96% Airbox Pressure 1007 hPa Dewpoint -25.4C Coldplate C 23.34C Coldplate D 24.01C Chiller Flow 2.3 l/m Chiller Setpoint 15C Note that airbox temp rose to 40.3C after awhile. Experimented with chiller temp and verified that dropping 5C started slowly cooling the airbox. Got down below 39c, but decided to return to 15C on the chiller for comparability with lab data. May want to change standard operating temperature in future, but table that for now.
- Wave8 beam monitor in sample chamber appears to be blocked by the liquid jet shroud so we're unable to provide witness flux monitoring tonight....shroud will come out tomorrow so we can try again.

Performance
- Darks in Autogain mode as Run 111
- Set Forced Gain 1
- Darks in ForcedGain1 as Run 112
- Set ForcedGain2
- Darks in ForcedGain2 as Run 113
- Create pedestals with 'makepeds -J'
- Collect flat field off Cu foil as Run 115 (3e-4 attenuation)
- Move detector back 400mm, same attenuation, hopefully flatter field as Run 116.
- Move detector up close, set attenuation @1e-3, flat field as Run117.
- Jacking up to 100% beam we are burning through the Cu but not getting any switching.
- Try scanning foil to catch a bright shot before it burns through (Run 118)
- Switch to metallic glass target @100%, scan to burn new holes in Run 119.
- 1e-3 attenuator on metallic glass for flat field in Run 120.
- Start water jet. 100% beam and water ring in 121 and 122.
- Lysozyme jet in Run 123 & 124:
- Place detector behind gate valve, vent, remove liquid jet shroud.
- Insert Ag behgenate, check out Wave 8 timing (no longer behind the shroud).
- Kaz is able to verify Wave8 is timed in properly.
- END DAY ONE.
Day two was mostly washed out by inability to run the detector due to DAQ config error. Did verify timing delay or 231us.
Day 3: Looking to generate enough flux per shot to trigger autorange in the JF. Problem is that fluorescence foils burn through immediately and we see greatly reduced flux. A script has been written to reposition the foil once per shot so that we're continuously using new foil.
- Sample ladder has metallic glass, 25um Cu foils, and doubled Cu foil loaded.
Plan to go:- Performance
- Force high gain mode
- Collect 1000 darks for analysis (Conny test 1; pedestals, noise, bad pixel map)
- Force medium gain
- Collect 1k darks (C2, pedestals/offsets, noise, bad pixel map)
- Force low gain
- Collect 1k darks (C3, pedestals/offsets, noise, bad pixel map)
- Offsets due to ambient visible light
...
- Mechanical
- Verify range of motion (done by CXI)
- Verify gate non-interference gate valve operation (done by CXI)
- Record encoder readings for position scaling
