| 1845 | Begin LHe transfer (~7%) |
| 1939 | Found the ozip format daq didn't write synchronized pulses to the data but the IZIP format daq worked fine. |
| Modified DAQDAQ2.vi to use IZIP format daq software (v. 20110525). The event rate of the izip daq at trigger level 40 ADC bin is about 30 Hz. | |
| 2000 | End LHe transfer (~85%) |
