COMMENT ON Remove 1 amp trim cards from the Peppo/Bubble line

Log Number: 3847971Logbook(s): Body: 

There are a number of suggestions regarding the configuration control of these magnets. With the cards removed and magnets stlll on the beamline, the correct thing to do is designate them 'Unpowered' in CED, remove their channel assignments from the trim rack, rebuild the controls, and reboot the ioc. Reboot and CED merge can be delayed to a time convenient to Operations. i understand this section of beamline will ultimately be removed. If beam is put in this line prior to that, we can easily reactivate these channels.

M904 and M905 region pressure improving

Log Number: 3847969Logbook(s): Entry Makers: poelkerBody: 

Pressure in the 904 and 905 region is getting better. I moved the two pumps on upstream cross to UHV supplies where they read 20uA. On the downstream corsses the pumps read ~ 200 uA but two of the ion pump supplies operate at ~ 8000 V so the current is artificially high to some extent. I don't think we can open the valve yet. I bet the current continue to drop. WE only need one of the three pumps on the UHV supplies.

200 uA = 2e-7, and the IBC pressure per Andy is 1e-7, so we are getting close. I want one pump on UHV supply for machine protection

Hall D current lock max change lowered to 5

Log Number: 3847962Logbook(s): Entry Makers: rebeccajBody: 

Overnight the max change was raised to 15. Hall D current was doing some oscillating when coming back from a trip. Lowered the max change back to 5, and oscillations are no longer occurring.
