AE Match proceeding

18 hours 7 minutes ago
Log Number: 4484467Logbook(s): Entry Makers: alexsBody: 

After some initial bewilderment at the wild 9L vertical dispersion increase (fixed itself after running locks) and screaming AE02 IDX (the beam is *highly* responsive to the quad being used by qsutility, MQKAS10), the AE match is proceeding.

Fopt - after reverting changes

18 hours 35 minutes ago
Log Number: 4484463Logbook(s): Tags: Body: Fopt 7.9 completed successfully. The runtime settings include a sample count of 15, a minimum current of 4, and an operating regime of Standard with Excitation in 1S Region. The corrector and RF kicks applied were 0.488208 and 0.488208 volts respectively. The max. amplitude setting was 1 millimeters. The files for this run were saved in the directory /cs/opshome/hlapps/optics/diforb/26apr062121. The X and Y stability of the machine during the run was 0.0798238 and 0.0813557 (mm) respectively.

New stumbling block: 9L vertical dispersion now 1 meter

18 hours 42 minutes ago
Log Number: 4484462Logbook(s): Entry Makers: alexsBody: 

This is a head-scratcher. No changes that we are currently aware of were made to any magnets upstream of 9R besides cycling the world. The only other oddity we noticed while re-establishing beam to the B dumplette was that the North Linac gang phase had drifted over 4 degrees while we were off. Investigation is ongoing.

Plan Update

Now that MQK9A23 is back, AS quads are back on design. Now adjusting Vertical Beta quads to get IHAAE01 under 500 microns so we can attempt to compute a match.

Fig. 1 Shows x and y values under 300micron (success!!!)

Starting AE match...

Took MQA9R06 500 G*cm closer to design. Hopefully now good enough to match with qsutility

MQK9A23 not responding

19 hours 40 minutes ago
Log Number: 4484449Logbook(s): Body: 

MQK9A23 was not responding. Locally resetting the power supply from the front panel seemed to clear the comm issue. No faults displayed on the screen prior to local reset. local/remote switch was sticky but otherwise the supply is back up and running.

Plan for back half of swing shift

19 hours 45 minutes ago
Log Number: 4484445Logbook(s): Entry Makers: alexsBody: 

After conferring while waiting on MQK9A23 troubleshooting, a path forward has been settled on. As things stand, the beam is too large vertically to attempt an AE match with qsutility, and our attempts to get a better 9A match by adjusting quads with live Courant Snyder plots running have not borne fruit. The next step will be to first undo the existing AE match in the machine by setting the AS quads back on design, and taking another harp scan at AE02.

MQK9A23 not responding

20 hours 18 minutes ago
Log Number: 4484442Logbook(s): Entry Makers: shrinerBody: 

HystArea tried to cycle MQK9A23, but it failed after two attempts. Then we tried to cycle from the expert screen, but still nothing happened. Then we tried to reset from the expert screen, and again it did nothing. Finally tried to zero the current and, to no surprise, got no response from the magnet. Contacting DCP on-call.
