TM#2 with Ta#54 has been moved from the conditioning station to the west target station.

 TM#2 with Ta#54 has been moved from the west target station to the south hot cell.

The TM2 HS line was leak checked at SHC yesterday . 0.9xE-9 atm.cc/sec.Helium sprayed by Chad, NO leak.  It was helium pressurized at TCS this morning. Leak rat:2.5 XE-7 atm.c/sec. The result  is same as last time check. No concern.

TCS vacuum system and water system have been started as well. Everything looks fine.

Thursday, November 09, 2017, 10:40: BIAS / EL to 30 / 15 kV. 400 uA on BIAS

Bias was stable for 1 hour. Handed over to RIB ops for heater conditioning.

 The results of the various electrical check done on the target module on November 7th and 8th of 2017. Checks were done with the old Ta#54 target without a target and finally with the new Ta#55 target. See the attached PDF for results.

 TM#2 with Ta#55 has been moved from the conditioning station to the west target station. The field was measured on the access panel to the service chase and the field was found to be 430uSv/hr at one meter from the module.

TM2 has been connected in ITW. All turbo-pumps are started. Everything works fine.

The Source tray was inspected in the RH shop today by Anders, Friedhelm and Jens. The routing of the lines are satisfactory, however a design proposal to remove the ground electrode line will be made. This design will have to ensure a proper connection from the electrode to ground (using the window cooling lines). All other lines are OK at this point. Some fine adjustments are expected after brazing and soldering to maintain high voltage separation. Photos are available on DocuShare Collection-21401

Stopped MP1 today in preparation for the power outage over the holidays. both P-25 and P-26 breakers have been switched off to prevent inadvertent start of system

The old TM2 Source Tray from 2009 has been moved to Cyclotron basement this morning. Source tray was stored in location 9. The box was moved from the vault to the ante-room yesterday. No contamination was found on the box.

TM disconnected by David and Yasmine Feb 8th. One of the water couplings were leaking for a short while when disconnected. NCR 10836 submitted by Max

By Anders & David. Couplings will be taken apart for inspection.

Findings and photos from the inspections attached. The inspection was conducted by Anders, David and Maico.

The job is done. See attachment.

 TM#2 with Ta#55 has been moved from the west target station to the south hot cell.

Attached alignment check notes after brazing and fabrication.

First page lower half shows establishment of baseline using master jig

Second page top half shows the alignment of the target mounting plate jig and the steerer cone aperture.

Second page bottom half shows alignment of the master target jig. Master target jig needed the 9 pin and heat shield locating features removed to seat the target correctly.

Overall, source tray assembly sits .006" high on average (min .003", max .010"), .003" to the left with respect to ion beam axis.

TM#2 has been moved from the south hot cell to the conditioning station.

I did a helium pressure test on TM2 water lines at TCS. We will remove the TM2 source tray soon so this test is a reference check for future new source. The result:

Helium 70 psi, 2 minutes to each circiut. Leak detector  base LR.0.0x e-9atm.cc/sec, base pressure  0.0x e-4torr

Ta+(A)  0.0x e-9atm.cc/sec

Ta-(B)  0.0x e-9atm.cc/sec

Tu-(C) 7.8x e-7 atm.cc/sec

Tu+(D) 3.5x e-7 atm.cc/sec

Coil 2(PU) 0.0x e-9atm.cc/sec

Coil 1(RU) 0.0x e-9atm.cc/sec

EE 8.2 x e-9atm.cc/sec

MSP 0.0x e-9atm.cc/sec

Containment box window  0.0 xe-9atm.cc/sec

HS  no target and opened. No test.

All water lines on module side in TM2  should be in good condition according to this test . The leak response we found on B and C lines are from water block seals mostly.           

I switched off TM2 and TCS vacuum pumps. The TCS and TM2 will be under vacuum without pumping.
