Tuesday, December 12, 2023, 16:07  - Pumping down test stand overnight for testing tomorrow. vacuum good, turbos starting now. Four thermocouples attached inside. tc1: high on (+) TGHT leg, pins 1+2. tc2: at target terminal (+), pins 4+5. tc3: at target terminal (-), pins 6+7. tc4: low on (+) TGHT leg, pins 8+9.

 Wednesday, December 13, 2023, 09:32 : Vacuum at 8.2e-7 T.  Electrical team is finishing connecting the cables. Claim it will be complete at 11am.

 Wednesday, December 13, 2023, 11:41Started both tc loggers at 11:40 - important for offset time. Beginning ramp as well on ATTS TGHT. set vacuum values high at 1e3 1e4 to bypass ATTS interlock, which does not apply here. ramping to 600A with step increment 10A and wait interval 10s.

    ATTS TGHT claims ramping in progress, but increased voltage is reported only on the autoramp window, which reports increasing the target amperage by 10A each 10s. However, no increased voltage reading is reported there, nor is there any increased current. ATTS:TGHT:RDCUR and ATTS:TGHT:RDVOL are ~0 as well. No increased temperature on any of 6 tc channels.

Wednesday, December 13, 2023, 11:57 ATTS TGHT power supplies appear to be under local control. It also appears (low current right now) that the value reported in EPICS is 1/3 of the value reported on the master power supply. It may be that the epics value is per output of the individual 3 supplies, while the total output is reported on the PS display. Planning to now increase to 300A and reach steady state.

Wednesday, December 13, 2023, 12:13 : 1/3 ratio idea confirmed at 33A EPICS reading / 100A master reading and again at 100A EPICS reading / 300A master reading. 300A now reached. Waiting for 20min. Temps inside ~ 21°C. Temps on feed through terminals ~22°C

December 18 - January 15. Were not logged. Placed holder. Aurelia's tests. Included thermocouples in the oven & ionizer.

Issues with valve operations due to a leak in the solenoid valve above FC0. The HPA leak did not allow for sufficient pressure to remain in the lines to operate. The solenoid as changed this morning.

Thursday, January 18, 2024, 10:32: Roughing. Valves can be cycled. FC0 cycled. OK.

The coil PS control card is fried. Roughly since the beginning of December. The PS was removed.

See attached image.

New PS was installed on Friday.

Tuesday, February 20, 2024, 08:01: Check Coil  not responding.

Tuesday, February 20, 2024, 09:48: System check 2: TGHT / TBHT manually to 5 / 5 A. BIAS / EE / EZL to 1 / -0.5 / 1 kV. Anode to 50 V.

Coil set to 15 A, did not adjust.

Tuesday, February 20, 2024, 12:04: Coil PS SW1-7 switch in was in an "Off" position & wouldn't allow the voltage signal through to the PS. Switched to "on". Coil tapped to 7 A manually & back to 0 A ok.
