We completed the install of the new magnetic labels to the Kepco supplies on the Mezanine today.
While placing one of the labels, the power on the HAM-6 PZT driver was unintentionally interrupted. We contacted the control room and they verified that this glitch did not affect anyone and we could turn this power back on.
One side note, the supply in H1-VDC-C6 slot 26 LHS which supplies HI-ISC R3 & R5 (HAM-6 +18V supply) is nearly maxed out at 20V 17A in the Mezannine, see attached photo. The two supplies below it are the old squeezer +/- 18V. These are currently unused, disconnected at the racks, but still on (not sure why we keep these supplies on). We could alleviate the load by splitting up R3 and R5 with respect to +/-18V and using this +/- 18V for either R3 or R5.
The old squeezer rack will be reporpused for the balanced homodyne suspensions. This may require its own set of supplies. We will also have more ISC electroncis, so splitting the ISC-R3 and ISC-R5 18V supplies might be needed.
