Succesful Horizontal Wien filter HV evaluation

Log Number: 3876976Logbook(s): Entry Makers: chgarciaBody: 

The Horizontal Wien filter HV was ramped succesfully to spec 20 kV for 200 keV beam to provide 100 deg spin angle rotation. No changes in vacuum were observed.

Voltage was applied to simulatenously to the positive and the negative Horizontal Wien filters power supplies while monitoring vacuum in the 1l injector beam line.

First in the Postive Wien Angle configuration, the voltage was ramped at 0.5 kV per minute to 20.5 kV, and let soaking for abot one hour. No changes in vacuum observed.

Cycled harp, verified the limti switch and stepper motor are functioning. Injected a test signal into the preamp, verified the ADC read back on the harp expert screens. Verified the linear pot read back on the data analyzer. See attachments for details.

COMMENT ON North & South Linac AC Upgrade

Log Number: 3876946Logbook(s): Body: 

EESRF has discussed the potential impact of damage to the M. O. Drive Line during this installation. We suggest there be a cover/s made out of Unistrut and sheet metal or plywood that will cover the effected area or areas depending on how many areas are being worked a one time. These covers should be movable to be used as needed at each location. It should be noted by ALL Jlab staff and the members of the A/C contractor crew the sensitivity of the M. O. Drive Line and the impact construction may have on beam operation during the run.
