It looks like most of the cavities on 1L07 and 1L22 can be operated. It would be great if some operators on swing and owl shift can run FE onset measurements on these two zones. The cavities should be taken up to quench in SEL mode with an admin limit of 22 MV/m. Please make sure that provide information on this ATLis as to the status of any cavities that are attempted. Also if there are any cavities where you can not exceed the previous operating gradients so that we can schedule some pulsed processing time. Once the data is taken Harshani or I will download it for further review.

2L03 CPS: 454 Vac at input to High Voltage Transformer instead of 480 Vac. 0 to 10 Vdc control voltage at 9.8 V at the SCR Bank input when a full on voltage of 10 Vdc requested. Not sure .2 V is the total cause of the missing 30 Volts. Investigation to continue tomorrow. Techs: G. Kepler, A. Schoene, X. Gomez and S. Holben

To reach the desired 119.5 MeV we'd need either 0L03-4 or 0L04-3 back in play. For now I think we'll set up at a slightly reduced energy. Veryfing our setup to FC2 first.

All the fibers coming from another rack are in place, except short fibers that goes from ADC to the VME crate which are installed after installing Moller ADCs.

The cisco switch is already available in the rack with Hall-A network from the installed fibers. The switch might need a reset to have proper Hall-A DAQ subnet, which will be done in co-coordination with Matthew from CC.

Sounds like all needed fibers are in place -- true?

It's not clear to me that the cisco switch with Hall-A network is in place at this time. What's it's status?

Completed Sorrenson supply replacements and checks in the North Linac. Replaced Sorrenson solenoid supplies in 2L22-8, 2L24-2 and 2L26-4 after removing and taking to Larry and Matt for repairs. Problem with supply current readback on 2L26-4. Only getting 15.68 amps on the readback instead of 31.5 amps. Checked control cable and connections but still getting low current readback even though it is set on the front panel adjustments. Will have to recheck and T/S tomorrow. Techs: Chris, Larry, Trey and Matt.

HCO was done on the Trim Racks in South Access service building, and all magnets where set to +/- low current for 30 min and then cycled. All magnets and Trim Rack are ready for operation.

All 20 Amp Power Supplies in the South Access service building, has been powered on and place in Standby / Remote mode.
