MSSG:

We have completed all work at YB006 dipole. That included a whole magnet flush for 1/hr, LCW system clean out into trence for 10/mins and 10/min magnet rinse. Hooked up magnet and did a 10/min leak check on all circuits. DC power and RAD notified and locks removed.

YB006 Is ready to go.

What outstanding teamwork! Thanks to all.

MBC4A27H might need a new trim card

Log Number: 4519078Logbook(s): Entry Makers: schoeneBody: 

Card seems to be misbehaving, getting worse in the last few days. See attached plot for mismatch frequency. Purple trace is another magnet on the arc to help eliminate times when the trims on the whole arc were cycled.

Log Number: 4519069Logbook(s): Entry Makers: samariBody: 

Me and Victor were able to get solenoid scans in for both the 1 um and 5 um targets in the nominal 46.5 degree Wien angle configuration followed by an attempt at a nominal energy spread measurement at the 2D spectrometer by making the early 0L a drift and getting an x emittance measurement backpropagated to MQJ0L01.
