15:04 bPlast was left powered over night. Powering up to check noise conditions - also to check shifting of Germanium baseline (no change observed).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; TEMP OK.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Noise condition the same as yesterday when platform was moved in. Noise in aida01 and aida09 due to single channel failures (?). Attachments 1-3.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 9/16 &lt;20kHz, max 176k

15:30 Changed drainwires ground from 4V (Ch3) -&gt; 29.5V (Ch4) out on R&amp;SMP4040 PSU. Attachments 4-5.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; No change in noise observed.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 9/16 &lt;20kHz, max 187k

15:49 Connected PN 300 ground to R&amp;SMP4040 4V (Ch3) output. Noise decreased in many channels aida09 does not have a noisy channel anymore (??). Attachments 6-7.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 10/16 &lt;20kHz, max 158k.
