Injector Restoration, D Moved From B to A Slit

Log Number: 4492796Logbook(s): Entry Makers: bschaumlBody: 

Steered beam from the gun to the ILD without much trouble. Fig. 1 is the initial orbit and 2 the final orbit, both with C beam. Fig. 3 is B beam and 4 is D beam. Fig. 5-8 show the chopper viewer as found, with D beam on the B slit, and D beam moved to the A slit by way of the laser phase the SME recommended a few nights ago. As shown in Fig. 9-11, collinearity with D beam was unfortunate after this change, so I walked the laser phase back a few degrees until it was... more passable. Harp scan at 0L10 was very close to the prior one, so I think we might be okay in the injector.

MXC7S06M mismatched, DCP on call helped resolve

Log Number: 4492785Logbook(s): Entry Makers: dthomasBody: 

When cycling boxes, MXC7S06 mismatched with noise fault. Similar occurance on 4/12 day shift, but sliding the current didn't work.

DCP on call instructed us to:
Take the dipole and shunts for ARC7 to 0, power off, and then power back on.
We did this, went to setpoint 2, and cycled.
Seems to have resolved the issue
