| 1700 | Filled N2 cold trap. |
| 1955 | DCRC33 phonon triggers (10, 24, 12, 18) on 4 channels |
| 1955 | DCRC30 phonon triggers (26, 10, 16, 8) on 4 channels |
| 2059 | Channel B and C on DIB1 looked too weak. Adjusted the bias the the new triggers are (28, 18, 14, 12). |
Phonon channels
QET sensors are biased at ~250mOhm on the Rs curve in the plots. Front end gain = 5 (this is usually large enough to ensure a 300-400kHz bandwidth) and Output gain = 1. Tower temperature is 69.1mK.
