Run 15

Run 15

Summary

The neutralization holding time of G16K is about 15min. Phonon sensor responses look OK except C1 on Side 2 is a bit weaker. But this could be due to the QET bias point difference.

Setup

Table 1: Run 15 setup
Detector	G16K
Tower	T1
DIB	1	2
Face	2	5
Side coax	ZB1-1-9	ZB1-1-6
SQUET	ZC23	ZC70
Stripline	#19	#20
Readout	DCRCv3

Electrical checks at room temperature and 77K were OK. The tower was slowly cooling during the run. The base temperature drifted from roughly 63mk at the beginning of the data taking to ~53mK at the end. We didn't use the Am-241 source this time. Only the external Ba-133 source was used.
