Started ramping up HV, EE and EL together. First small spark at 20.5kV on bias, no reaction in other devices.

Note both BIAS and EL are off in their readbacks. See table below

Saturday, April 27, 2024, 10:23 :

Spark on HV only at 25.5, couple sparks from here to 33, then at 33 starts real conditioning.

EL is reacting to some of the sparks, not sure if this is just electrical noise or not.

lots of trips above 60kV on the set pt. tripping off turbos and gauges. IG2 needed the controller reset.

RESULT: Got to 64.5 (actual) 62 (set point) with quite a bit of sparking over 60kV. Will go the rest of the way to 73 in the next days. Data dumped as isac/data/TM3_HVtests_Apr272024.dat

Ramped back up to 60kV reasonably easily, couple sparks and turbo trips.

Went up to 64kV (set point) with a lot of difficulty. Data dumped as isac/data/TM3_HVtests_Apr282024.dat

TM4 has been moved from SMP to SHC. Adam and I did the move. the move is smooth.

TM3 helium pressure test and electrical check with new source tray at TCS were done yesterday. The results are excellent. See attachment

TM3 module top helium spray leak test was done yesterday.  No leak on TM3 module top @ LD base leak rate 0.0 x E-9 atm.cc/sec.

TM3 has been moved  from SHC to TCS. The move is smooth.

Wires were pulled in TM3 and service cap was closed up again:

Einzel lens wire (30kV kapton), routed in the pumping duct and attached with #10 ring tongue to EZL feedthrough in service cap

4 steerer wires, routed in th pumping duct and attached with push on connectors to the 4 SHV feedthroughs on the module side panel. Coax grounding sheath is cut back by about 3cm.

Multipin cable bundle #1, routed through the left cable tube in the service tray then along the heat shield water lines (with PEEK zip ties) to feedthrough A.

Multipin cable bundle #2, routed through the right cable tube in the service tray then along the heat shield water lines (with PEEK zip ties) to feedthrough B. This bundle contains the EE wire as well, which was branched out after exiting the service tray and routed along the gas lines to the EE feedthough. It was attached with a smaller (size?) ring tongue to the EE feedthrough. Do not use this wire again, very fragile. Use the Accuglass 30kV wire instead.

The multipin wires touch the back of the water blocks in the source tray (same as in MT2/4, so far no issues with that) and they also touch the COIL lines in the service cap.

The EZL and steerer wires are routed along the floor of the service cap.

Due to the difficulty of the installation, there is no metal braid over the multipin bundles in the service cap.

TM3 water lines helium spray leak check at SHC is done. No leak has been found on all lines. seeattachment

ITH:MP1S pump inside lubricant was changed today. old lubricant is dirty with dark color. they are stored in sealed waste oil jug and stored in silo area. Pump has been installed back and started. It works fine.

Monday and Tuesday, I started TCS water system and enabled the TCS chillers auto stage in/out. I saw chiller 2 in/out three times at 17C and 21.8C without issue.   TCS water system works fine. The test is finished.

TM3 new source tray was transferred into SHC on this Tuesday. one hook arm of transfer jig is very close to optic tray tube when engaging the jig on transfer frame. tube side hook arm should go east side a little bit further to avoid the tube.  Also the HS tube top lines to  transfer frame beam bottom distance needs to be watched closely when hooking on the frame.Help from HC window is necessary. By watching on this details, Source tray are successfully moved into SHC with crane controlled locally in TH.Transfer frame was retrieved back to TH. It was cleaned, bagged and stored in TH.

Tm3 was moved from silo to SHC yesterday. the move is smooth.

water are supplied to both ITE and ITW. I did a general inspection on HALCW system. Two small leaks on 2" shut off valves are fixed. No other leak has been found so far. all water flow meters work fine. MP2 pump discharging pressure is ok which is just above 100 psi on local gauge reading. pump noise are low. pump body temperature is less than 45C which is good. 

both high active pumps ITC:MP1 and MP2 are refurbished by RH group Maico and Peter. Pumps have been installed back to system with new inlet/outlet flange gaskets. high active water surging tank is refilled with water and pumps were primed. I asked operator to switch on pumps separately. Both pumps work fine. They are quiet and pumps discharging pressure is a little bit better comparing to before refurbishment. Nitrogen gas is injecting into system. O2 level is decreasing and R is going up.

2024-04-09: Joel.S checked pumps phase current draw: MP1 16.8 to 17.1A on each phase. MP2 17.0 to 17.2 A on each phase. They are normal. Pump body temperature are below 45C which is fine. 

On April 2, 2024 the wrist on the SE manipulator of the SHC (Serial # 7986) was swapped with a rebuild unit originally from SW position (serial # 8106). The "new" wrist was a wrist + tong assembled unit with the tong cable being routed if-front of the spacer A-14118 rather then behind as in all previous replacements (see attached pictures). This change was a result of a discussion with Central Research's senior repair technician who informed us that the original routing was incorrect from the factory. This can be seen when inspecting unit we have on-site that are still in the original configuration from the factory as about half are routed one way and half the other.

Tm3 has been moved  from SHC to silo. The move is smooth.

ITE entrance module top and module flange o-ing to tank have been leak checked. no leak at 0.0xe-9 atm.cc/sec. things are double checked.

Tm3 has been moved to SHC from silo. the move is smooth.

ITE entrance module has been reconnected in ITE pit per document 190510.

ITE entrance module has been moved from TCS to ITE. The move is smooth.

 Thursday, March 21, 2024, 11:33 Three channels are available now for thermocouple readouts from the Target multipin. Wiring from the PLC modules to the connection terminal blocks and labeling done.
