I finished pulse processed 1L07 today and 1L09 yesterday afternoon. Please do FE onset measurements on swing/own will it will no interfere with recovering other zones. When you turn off up stream and down stream zones (several either way) close the upstream beam line valve on 1L06 and the down stream valve on 1L10 in order to avoid dark current from curupting the measurements.

Figs. 1-3: Collinearity as found
Fig. 4: C-beam as found to the 4D
Fig. 5: C-beam on 4D viewer after phasing 0L03 & 0L04
Fig. 6: Changes to phases and energy lock cavity
Figs. 7-13: Variation of B-beam and D-beam on 4D viewer with changes to phase. They're both kinda funky and not responding to phase changes as I might expect; exhibiting a sort of s-shaped path on the viewer as I swing phase around. Perhaps something strange to do with the optics variations between beams due to the collinearity being off? I'll move on to seeing if I can improve that.

Removed valve simulator boxes for valves VBV3C20 and VBV3H04. Both showing actual position of valves in epics.
Vacuum group is still pumping on the 3H04 section of the beamline. Still not good enough to keep power supplies for VIP3H04, VIP3H07A and VIP3H07B from faulting off. Talked to Vacuum group, VBV3H07 valve might have a small leak.

Body: 

Updating the guidance for the operation of the gun high voltage system.

1. Ops can use the standard gun controls to ramp the gun on/off as usual and as needed to support the program.

2. If there is a gun fault unrelated to the PSS (meaning loss or drop of PSS-A/B chain) contact CIS on-call before restoring the gun voltage.

Thanks for your patience,
Joe

A rough set up to in line dump beginning with the set up known to FC1 from Max yesterday. I Downloaded design optics and tried to lightly modify the 0L upstream quads to get good beam spots that match the aspect ratios. I was able to set up 65 uA CW to FC2 with decent transmission but collinearity with the other beams needs work. Afterwards I did a rough steer to the ILD with everything downstream of MQJ0L04 on design. Handing over to Ben to double check all of my work before Max gets in.

Moser, this "top-hat" is not waveguide top-hat. We are not using waveguide top hat for the HOM survey but using RF cables to connect the HOM couplers on the cryomodule's top-hats. The attached summary document for the HOM survey at CMTF has provided all technical details.

1L07 has had some level alarms that seem to be related to RF testing in the module. The level signal developing an oscillation of this nature may indicate there is helium boiling happening inside the module.

DC power came in the control room to let us know that SA01B07 trim rack was down. I found that odd because we never received an alarm for it. I dug through the alarm handler and found that indeed the rack power and associated magnets are in alarm but they aren't propagating up the nodes.

Makes me wonder if there are other sub nodes doing the same thing...
