TM4 HS and window line are helium pressure checked at TCS. 70 psi helium 5 minutes. No response @1.2XE-8 atm.cc/sec. They are leak free.

TCS is argon vented. TM4 is disconnected at TCS.

ITW water interlock check is finished. Everything is good.

ITW secondary vacuum was bad in last two days after TM4 was connected in ITW. Today when check the exit 2 module, I found a small needle valve on exit 2 module top was slightly opened for some reason in past months. The valve is closed . ITW vacuum is returned to normal status.

TM4 was connected in ITW this Tuesday. See attachment for checklist.

TM2 has been connected at TCS this morning. helium pressure test on Tm2 HS line is done. No leak.

TM4 HS Leak check result is good . No leak. electrical check after target installation: Bias to chassis 550 Mohm. Coils are shorted each other and shorted to 60 KV bias. ABCD to 60KV bias 500V Megga measurement are 100M at least which is good. EE to bias are OL at 500V. The electrical check result is good.

Tm2 with Ta 59 has eben connected in ITE. Turbo pumps are started. See checklist

TM4 was disconnected in ITW.  See checklist.

TM3 was moved into SMP Oct 25 morning.  After two nights pumping down, SMP CG1 read 30mtorr this morning.  The pump is stopped. SMP will be vented soon for TM3 moving back to silo.

Feibiad gas line for ITE and its adapter fittings for TM2 are tested today by installing them on a dummy water stem. No leak on VCO fitting, adapter o-rings, and all Swagelock fittings of this assembly. Manual valve on gas line works fine.  The positional check on gas line between TM2 and ITW will be fulfilled next Tuesday during module disconnection.

Helium pressure leak check on TM2 HS line at TCS is done. No leak. Also, Helium are sprayed to gas line adapter and fittings. No leak. TM2 is connected at TCS. Anode plug on TCS is connected to module 52pin connector. Water system is started. Vacuum pumping down is good. HV cover will be installed today.

TM2 was connected in ITE 12th Nov. attach checklist

TM2 was disconnected in ITE yesterday.

TM2 has been connected  in ITE.  All turbo-pumps are started.

HALCW MP2 is switched onnow. There is a small amount of air trapped in system. The pump works fine.  Water level and system resistivity will be monitored for a while.

LALCW P5 and P6 are switched on  for cooling HALCW.  HALCW MP2 is in operation now.

Target hall crane does not work properly after TH crane main power is switched off during Christmas time in control room. I switched the main power back this morning. The only movement could be operated is crane rotation. Power is supplied crane. The control  on N-S, E-W and up-down movements do not work. We had the same problem last year. After trouble shooting, It was pointed to a PLC battery issue. Control group changed the battery and reloaded the program. I guess  the battery is drained out very fast for some reason. So, We face the same problem again this year.

Adam checked control room main power supply. I checked in TH crane again. The problem is still there. We can confirm this is the same issue like last year. 

HALCW MP2 is switched on this morning after yesterday cooling tower maintenance. LALCW P5 and P6 pumps are started by isac operator  as well. The system is good so far.
