TH shut down jobs are processing as scheduled this week. Discussed with Don, and we think the jobs scheduled in next week should be processed as we planned. See attachments for updated schedule.

I updated the schedule today. See attachment 3, 4 for updating.  2015-Mar-10.

2013-Mar -13, I updated the schedule to show the jobs we finished this week. See attachment 5,6

This schedule is following Dons schedule on module moves. See attachments for updating.

2015-03-27: Weekly update the schedule. The shut down job is close to the end. See attachment 3, 4.

Updated schedule this morning after last Fridays ISAC facility support group meeting.

Updated schedule on 2015-April -02. See attachments 3,4. The scheduled all shut down jobs are done on time.The TM2 move to SHC will be delayed to May.There will be a new beam running time TH activities schedule (start from April 15) replacing this shut down schedule on next time  weekly update.

Tom Kauss corrected the TH crane  festoon cable loops. He lubricated festoon cable wheels as well.    The maintenance is done.

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.

Niel Wong came and had a look at the system. We decided to close the circuit as the water is no longer used with the new power supplies. The circuit will be monitored, but not repaired unless it is needed again.

 Due to the water leak, the expansion tank needed topping up. It was filled from 14 in to 20 in. See work permit I2014-12-15-2.

During the last ITE run with the SiC#44 target, the ITE:TBHT controls card was fried twice. The first time we put in our spare, and the second time we just continued to run without controls readback. For the C#4 run starting Oct. 19, we used the conditioning station supply. As soon as one of the other supplies is fixed, we will install it in the conditioning station. The equipment list (https://triumfoffice365-my.sharepoint.com/:x:/g/personal/cbabcock_triumf_ca/EQPffP4p1P9JqEDWIHGRPfsBVDSQjMCv-M8ZNg4ngkyGHw?e=fnLVYe) tracks these movements.

 The flow meter on the primary side (TCS:DIF2) of the conditioning station is broken. I investigated and there is flow, the gauge is not fouled, and the PLC does read back when current supplied. The gauge is also reciving 24V but the output is 0V and 0mA. I will contact ESC and the supplier.

NOTE: If cooling is required, the compressors will have to be run manually. Make sure to switch it off again when the water has reached an acceptable temperature.

The staging did not work properly this morning. Dave Morris have been contacted and will look into it.

TCS water system resistivity analyzer has been repaired. Two diodes and one capacitor on PS board were broken. They were replaced. Installed analyzer back and tested it in system. it works fine. Operator closed e-fault, removed force on TS5, and enabled alarm on TS5 and TC1.

The system works fine. All water signals to TM4 at TCS are normal. HV cover is installed on to TM4 at TCS.

TCS water system has been started for functional test. System parameters including  pressure, all temperature sensors, flow rate sensors, resistivity are ok. I will watch on chiller CP1/2/3 in rest of the week and make sure chiller CP1/2/ 3 auto stage in/out work fine.

TCS water system  five filters were changed yesterday by plant group Dan.T. Service labels on filters are updated.  No water leak after job.

TCS water system filters annual replacement has been done. Plant group Dan Tower finished the job and updated the inspection tags .

 TCS water system worked fine overnight. I turned off TCS water system at 6:16 AM this morning. Start of purging TM2 water lines for helium pressure test again this morning.

2016-4-28 7:58AM. Disconnected TM2 water lines at TCS. Purged them with compression air each for 5 minutes. 

Argon venting on TCS and TM2 is processing

Plant group changed TCS water filters last Friday. 4 filters on resin can inet /outlet sides and filters(4 in one cartridge house)on pump return line have been changed. Triumf maintenance tags on filters have been updated. No water leak after job. The TCS TK2 water level dropped  from 20" to 16" because of the job. I will refill the level to 28" today. 

TCS:TK2 is refilled to 28".

TCS was argon vented this morning between 7:00 to 8:30 am before module was moved to ITE.

TCS was argon vented this morning between 6:00 and 7:30am for TM4 moving to ITW.

TM3 TP1 and TP2 work  fine in past 4 days. During operation, The current draw on pumps were 0.7A to 0.8 A. TM3 will be moved back to silo tomorrow.
