TMS:IG6 had continued communication errors post power outage & would not switch on. After a power loss, IG6 switches automatically to Filament 1. Filament 1 is burnt out.

Thursday, January 24, 2019, 08:14: TMS:IG6 fixed. Switched from Filament 1 to Filament 2. FIL2 runs ok.

Instructions from Edi:

-Using the + / - keys move the cursor on the control box to select FIL2. The control box is located above the beam line turbo pump control boxes / inside the black cabinets under the TS.

-Press ok to switch FL2 : ON

-Turn IG6 on with the computer (EPICS) before it times out.

-Now IG6 is connected and can be switched on / off from the computer.

Backing "mini pump" testing.

-Open gas lines & auto ramp (If using HV, close up the back)

-HV on

-Close SV5, SV4, SV3 when ready. Wait until stable. Take measurement (1/2 hr approx)

-Turn down HV. Interlock, leave heaters on.

-Turn on mini pump.

-Open, SV4, SV3 carefully.

-Open MP valve. Wait 15 min. Close MP valve

-Carefully open SV5. Quick open & shut. Monitor vacuum 7.0e-06T trip limit.

-Monitor / record. Carefully open & close until stable.

-Close up TS w/ interlock

-HV on again & test.

Friday, May 31, 2019, 12:33  Using Brad's tuning values we see a nice peak at the first set of wire scanners on the y axis but nothing on the x axis. Using CB2, went from 200V to 900V in steps of 100V and saw nothing on the x axis. This seems to indicate x axis scanner is broken. Proceeding without x axis readout. Also tried with CB1 steerers, same effect.
