0420	Brought neutron source from safe. Data series 07110603_0418 and onwards are neutron data files.
1040	Data series collected (Cf-252): 07110603_0418 07110603_0507 07110603_0557 07110603_0646 07110603_0736 07110603_0825 07110603_0915 07110603_1004
1044	Cf-252 source was put back. The data after 07110603_1004_F0003 will be background data.
1759	Stop DAQ. Disk space is low.
	Data series collected (background): 07110603_1053 07110603_1142 07110603_1230 07110603_1319 07110603_1407 07110603_1455 07110603_1544 07110603_1632 07110603_1721
2048	Stat taking data 07110603_2047_F0001 with the neutron shield on. Cf-252 source is 17.5“ from the mu-shield, 8” poly shield between source and fridge. Same DAQ settings as last run.
	N2 cold trap is filled.
2050	Shielded neutron runs started: data series 07110603_2047 onwards.

First Look at Phonon Data

Figure 1: Qsum from data series 07110525_1928 (3.2768 ms trace length, Ba-133, phonon and charge signals).

Figure 2: Phonon Response. Outer phonon channels A1 & A2 are not included.

Figure 3: Box plots after cuts (top), and when Qsum on Side 2 lies between 50 keV and 80 keV.

Figure 4: Box plots after cuts (left), and when Qsum on Side 2 lies between 50 keV and 80 keV.

Figure 5: Relative Phonon Calibration (left) and Yield vs. Phonon Energy (right). Luke phonons are not taken into account.

Figure 6: Qzpart (left) and Yield (right) as a function of time.
