0045	Place Ba-133 source 13“ under top of mu-metal sheild. Take charge-only data overnight with trigger thresholds of 40 ADC bins on all charge channels. Data series: 07110502_0044 taken with old DAQ (oZIP format).
	Fill N2 cold trap full.
1025	Computer disk was full and error occurred at 06:34 this morning. I stopped the DAQ and put the Ba-133 source back.

1053	Flash detector
1250	Fill N2 cold trap full.
1730	Some issues with reducing the iZIPv4 data. Been working with Lauren to sort them out. Currently ongoing.
1800	Looks like problem was in the DAQ code. Jeter sent a new version. Have downloaded it to the laboratory computer. Will try it out later tonight.
1920	Have been trying to reduce data series 07110502_0044, but encounter the error: NoiseBuilder::ConstructMinMaxDistrubution ERROR in ordering of MapOfZipPulses or MapofNoisePulses!noise data is 193, and pulse data is 4001006 when running NoiseGen. Not sure what this means, but no such error crops up when attempting to generate a filterfile from data series 07110428_1946, collected under the same conditions. Are these files corrupted?
	Perhaps this isn't worth investigating in great detail at the moment seeing as we have received a new version of the DAQ. Time to test it out.
	Delete files taken from 2011/04/27 onwards on DAQ computer to make space.
	Stop flashing detector.
2010	Start data series with new DAQ: 07110502_2009; charge-only; trigger set at 30 ADC bins for each charge channel.
2105	New version of the DAQ seems to have done the trick. Ran NoiseGen and BatRoot on the first file successfully.
2120	Stop taking data. Start flashing detector.
2215	Stop flashing detector.
2300	Start taking data with Ba-133 source, series: 07110502_2259; charge-only; trigger set at 30 ADC bins for each charge channel.
2350	Fill N2 cold trap full.
