Verify Nominal Operating Voltages and Currents
Environmental
Test conditions:
...
- 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:
- 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)
...
- Mechanical
- Verify range of motion (done by CXI)
- Verify gate non-interference gate valve operation (done by CXI)
- Record encoder readings for position scaling
