0955	Fed Cricket 3 pellets.
1014	Stopped flashing detector.
1030	Filled LN2 cold trap.
1805	Fed Cricket 4 pellets.
2330	DCRC30 has failed again. This time, we can't revive it. Board unable to power up despite its efforts. Sten has been emailed, but it looks like we've lost DIB 3. Board is likely to return to Fermilab for repair.
	Finished assigning QET biases and took first phonon data set! Albeit with two DCRC boards… 07120719_2328. Just one file of trace length 3.2768 ms, trigger delay 400 μs, no charge bias, triggering on all phonon channels but C2. DCRCs plugged into DIBs 1 & 2. DIB 1's phonon traces looked very good. DIB 2, however, was a different story: only one channel appears to behaving itself. Will have to revisit these channels.
