3h of PEM injections

Sharan Banagiri, Philippe Nguyen, Robert Schofield

After the calibration sweep, we made acoustic and magnetic injections in the electronics bay and LVEA. We also made a couple of impulse injections.

I planned to note last night that for this week, Tuesday to Tuesday, there may be equipment that is on that is not normally on during the run. This includes the computer by the PSL and 3 amplifiers that we leave on so that we can inject from the control room. We sweep normally, with these exceptions, before we approve the return to observation mode.

Time: 21:08 UTC to 23:57 UTC
