NiO#2 has been moved from the south hot cell into spent target storage. It was placed in pail 111 in slot 3C of the storage vault. It was 76.4mSv/hr upon removal from the south hot cell.

TM#4 with NiO#1 has been moved from the south hot cell to the conditioning station. Move went well.

See attached PDF for details. 60kV Common to the target is low at 343k but I've been told will work. Test will be done again on Friday after it has sat a few days under vacuum.

Electrical check of the TM#4 with NiO#1 was done again today. see attached file for results.

 TM4 with NiO#1 was moved from ITE to the SHC today. The move went well with no issues.

The NiO #1 spent target was placed into storage today. It is in pail number 01 (101 on Vault Status page) and located in slot 4A of the vault. It was 35.5 mSv/hr upon removal from the south hot cell. See attached PDF for vault details.

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.

UOx was removed from TM4 yesterday and NiO#1 installed.

Video was taken.

Main stand-off insulators continue to deteriorate.

leak detector pumped down to 0.0xE-9 atm.cc/sec, and 0.0xE-4 torr. All high vacuum gauge readings at CS and TM4 are at low -6 range from 2.2xE-6torr to 4.2x E-6 torr. Applied 80 psi helium  to heat shield circuit for 5minutes and there is no any response on leak detector. The heat shield circuit is leak tight.

TM4 had been connected in ITE. Six turbo pump had been started . thepumpming diwn is very good so far. The water interlock check on ITE and TM4 had been finished and everything is good.All water signals are strong and constant by visually checking.

I disconnected TM4 in ITE this morning. The heat shield circuit has been purged with air.

TM2 has been connected to ITW. Turbo pumps are stared. ITW pumping down is fine so far.

ITW primary and secondary vacuum vessel leak check are done. There is a 5XE-8 atm.cc/sec leak on Exit service cap NW side square panel.  The leak is small. And, it is close to ITW TP3 so it is not affect ion beam line vacuum during operation. We will replace the seal on the panel later.   The rest leak check on air to vacuum seals are good. TM2 water lines are pressurized with 70 psi helium. We did it  3 hours after water lines are purged. No leak was showed during the check.

2021-02-24th: The o-ring on exit 1 NW side square panel is replaced by David Wang and Frank Song. 

 TM#2 with Nb#9 was moved from ITW to SHC and then with no target it was moved from the SHC to the SMP.

 The results of the various electrical checks performed on the TM#2 with and without the Nb#8 target attached.

 TM#2 with Nb#8 has been moved from the south hot cell to the west target station.

TM2 has been connected to ITW. All turbo pumps are started. See attachment for connection checklist.

Maico and Travis moved blocks from ITE to ITW yesterday

The 2A2M19 beam profile monitor did not work and was e-faulted. After initial troubleshooting 2 blocks were removed form ITW to inspect the entrance module where the beam monitor is installed. The cable was found not to be connected and was quickly fixed. Blocks reinstalled. The work was done by Maico, Travis and Anders

ITW Entrance Module was leak checked yesterday with the support of Vacuum Group (Dimo & Edi). The leak detector was connected to primary backing vacuum line. A leak response was found near the bellow for the beam profile monitor on top of the Entrance Module. It could be confirmed today by actuating the monitor, that the leak was indeed at that location. The plan is to move the TM and Entrance Module out for target exchange and repair, respectively. Drawings of the device available on ITA0200and ITA5128
