TM#4 with CS Test Target #1 (dummy target) moved from the conditioning station to the east target station. Move went well.

 Today David and I moved the module from ITE to the SHC. Move went very smoothly, David operated the cameras and has had basic training in how to manually lock out the controls.

 TM4 with CS Test Target #1 was moved from the SHC to the Conditioning Station. All went well. The welding cables came a little close to the cage, David will bend them in more in the future.

 Roughing pumps were turned on at 15:23 13/03/2013.

 Turbos started at 11:14. TP1S achieved full speed in less than 2 minutes. TP1 and 2 tripped at 9 minutes. Restarted and reached at speed after another 1 minute 20 seconds.

 Over the weekend Turbo pump one failed. It was attempted to restart the turbo in soft start but that also failed. Although the Vacuum was good enough to operate both Turbos are required to pass commissioning. As such the pumps were turned off at ~10:00 today. Venting started at 12:00.

The Model of the Power Supply (PS) is TSQLG 480-20/1500 and serial number is 2755.02.01.01.09.

We went to test the PS and supplied the required 480V and turned the local switch to on. At this point nothing happened, the controls screen didn’t light up nothing. We tried to run the PS in remote mode as that is what it had previously been set at and again there was no response. At this point I called the electrician the check that we were in fact supplying 480V. He checked all the way to the contactor inside of the PS (see attached picture). He also checked the 3 larger fuses and 6 smaller ones, they have not failed.

I have inquired with Jens Lassen who is more familiar with these PS and he has not had this issue before. He is going to have another look at the PS with the electrician specifically checking the 24VDC for the control board. Any further information or checks you could provide would be very helpful.

 This PS is needed for commissioning of a system and unfortunately this failure has come at a very in opportune time.  Although the PS is show to be several years old we have not actually used it aside from some minor tests ie does it turn on (it has previously).  I have phoned the manufacture to determine what else can be check and what the next steps are. Werner requested that I send an email (completed) so he could give it to their engineers.

 The conditioning station has been vented with argon. Time taken is not known but it is less than 3 hours. See attached picture for convectron gauge readings. CG1A is in air.

 David replaced the broken turbo pump this morning and I have started roughing at 9:54.

 Turbo Pumps have been started and are in normal operation. TP1 which has recently been replaced was started in soft start and had no issues. TP2 was started normally and tripped prior to reaching speed. It was left for a while and restarted. When restarted it was still at 17KRPM, it reached normal operation.

 The cooling package and vacuum was stopped today at 9:26 so the module can be move.

TM#4 with the CS Test target has been moved from the conditioning station to the south hot cell. Move went well.

 an electrical was done for TM4 with target C#4 installed on NHC.

TM4 HS line helium pressure test is done. 70psi helium pressure@ 3XE-8 atm.cc/sec . No leak.

 TM4 with Target C#4 was connected in ITE.

TM4 with C#4 was disconnected in ITE

 TM4 with C#4 is checked on NHC right after moving from ITE.

C#4 spent target was moved to the storage vault, in pail 277. Dose rate at approximately 1 m when leaving the hot cell was 164 mSv/h. The pail has been placed in vault location 4C. See updated vault layout attached.

TM4 was moved from the Conditioning Station to the East Target Station with C#4.

Post irradiation inspection of C#4 which was running in TM4/ITE was conducted at the NHC on Nov. 22 2022.

The yields from this target had been dropping and its behaviour was erratic, with the voltages on the tube and target jumping all over the place sometimes. The ion current on the FCs followed the voltages. We took this to mean the target container was breaking down.

Upon inspection we found the container looked pretty damaged - highly crystallized and distorted. The container had gone banana-shaped, but not in the usual direction. It had curved  in the direction of the ion source (see photos). The heat shield and other surrounding components were super clean, no deposits or marks at all.
