1523 Filled N2 cold trap. Got a new version of DAQ software. Tested and it worked. But it doesn't have the modifications I made. I'll do that later. Flash the detector after testing.
1602 Added recent modifications to the new DAQ. Now can flip the charge polarity independently.
2100 Stop flashing detector.
2150 Could not get DAQ to work - froze on first random trigger. Not sure what I'm doing wrong.
Start flashing detector.
2230 Perhaps the modifications have something to do with this problem. Stop flashing detector in preparation for taking data with pre-modified code.
2315 Start taking iZIPv4 format data series: 07110430_2312. Phonon channels are locked, but no QET bias has been applied. This is sufficient for investigating neutralisation.
