I started TCS water system and installed HV cover onto TM4.  The TM4 containment box is supplied with water also. TM4 is ready for conditioning at TCS.

TM4 is moved from TCS to SW silo this morning. The move is good.

TM4 is connected in ITE. All ITE  turbo pumps are started. I will check the pumping down process tomorrow morning. Everything is fine so far.

TM4 has been connected connect in ITE. Water is supplied to TM4 module only.

TM4 is connected at CS. All turbo pumps are started. The pumping down is good so far.

TM4 has been connected at CS which includes high current cables, water lines, EE cable, and Enizel lens cable. The HV cover has been  installed onto the TM4 service cap.The CS water system is started. All water signals are good so far.   Anders will start  HV and heaters conditioning on next Monday.

TM4 has been connected at CS. CS HV cover is installed.I made a pair of new cooling lines for TM window cooling at CS. The TM4 containment box window cooling line is connected to the HVC spare circuit now. I checked water flow visually, and it is good. The TM4 is ready for conditioning.See attachment for window cooling modification.

  I started 6 turbo pumps this afternoon. The TM4 and ITE are under pumping now. The vacuum is fine so far. We will see a better picture tomorrow morning. In order to keep the system pressure at 90 psi, I just turned on all the water to TM4 circuits. The water interlock check which related to TM4 water circuits is all done. I will do the rest part (XTpage related to 2A beam) next week once I turn on all the water to ITE. The ITE and TM4 will be ready for HV conditioning once the vacuum is ok.

TM4 heat shield helium pressure test and electrical check were done  at CS  last week. The results are good. NO leak had been found on heat shield circuit.The electrical check is also good.

Chad and i did a leak check on TM4 heat shield circuit with installed dummy target at SHC today. The leak detector is pumped to 0.0xE-9atm.cc/sec.Chad sprayed helium twice on each  VCR joints .There is no any response had been found on the leak detector during each 45 seconds waiting time. The TM4 heat shield circuit with dummy  target is leak tight so far.  

Chad and i did a leak check on TM4 heat shield circuit with new NiO#1 target installed. It took about 40 mins(much longer than usual) to pump down the circuit to leak rate 0.6x E-9atm.cc/sec and 0.0x E-4 torr o leak detector.

All vacuum lines and joints which connected to the leak detector had been helium sprayed and they are leak  tight.Chad sprayed helium on each VCR joints for 2 seconds every time. During 1min waiting time, there is no any response on leak detector. Chad repeated same test again for double checking and we got same result. Chad finally flushed the helium around the target heat shield for 10 seconds.we waited for 1minute and found no response on the leak detector. The heat shield circuit is leak tight at this stage. I will do a helium pressure test on this circuit when TM4 is in CS and under vacuum.

Chad and I did the TM4 heat shield leak check yesterday at SHC. The leak detector was pumped to 4.6 xE-9atm.cc/sec, and 0.0xE-4 torr after 1.5 hours pumping. Chad sprayed helium twice on both VCR fittings. There is no response had been found during each 45 seconds waiting time. Since the module moved to ITE directly,we didnt have helium pressure test this time. I  would say thee heat shield circuit is leak tight. so far.

TM1 has been partially disconnected at CS for tomorrow move. The CS TP1S is still running and will be stopped and disconnected tomorrow morning.

All ITE and TM4  turbo pumps are started. The east station pumping down is good so far.

TM4 has been moved from TCS to ITW.  the move is smooth.
