McCaughan noted that this cavity has a high GLDER (145 ppm) and recommend that we GSET-0 it. Given that we can GSET-0 this cavity without increasing trips per shift all that much, I didn't have an issue with doing so when we get the chance.
Took before and after measurements to ensure that it was indeed successful, and it resulted in a further alignment of Arc 3 and Arc 1 phase by about .25 degrees.
In figure 1 (before the change), one can see the difference in a phase angle error proxy (Arc3-Arc1 dpp) minimum is offset from the peak dpp in Arc1 by .25 degrees. In Figure 2, (post change) one can see they agree much better.
0L03 IF levels are 2-ish; for most of the rest of the legacy RF 1.0 stuff it's at 2.5-3ish. Do we need to bump the INJ IF signal up?
Cavity 1 LOPW oscillating between mid-30s and mid 50s in mW. Should be in the 70-100 mW range to control appropriately. Other cavities in the zone all seem to be in a good range. The cavity is presently on for the physics program, so must be reliable.
