 Wednesday November 30st: <br>

- 3 cameras (1 UV and 2 regular cameras)  were installed in the Service cap and the module was pumped down.  1 UV and 1 regular were placed on the East side of the module, aiming to water lines entering the Service Tray; 1 regular camera was placed on the South side of the module, aiming at the bottom of the blue insulators.

- started pumping down. <br>

Thursday, December 1st: <br>

- 1st HV test done. TM3 started sparking above 20kV. The cameras responses were consistent with the sparks. However, the screens were flickering and it was not clear if the responses were due to electromagnetic interferences; or due to cameras' gain change caused by high intensity light due to sparking.<br>

- added helium using the regulating valve. same results were found; <br>

Friday, December 2nd: <br>

- vented the module. <br>

- shielded the cameras' cables with aluminum tape. <br>

- removed 2 blue insulator (EE and HS) and shortened them by 1". They were found too long: HS blue insulator touching the horizontal HV water line; and the EE blue insulator at 2-3mm far from the HV water line; re-installed both shortened blue insulators.<br>

- changes the location of the cameras: 1 regular camera taped to the UV camera were placed South, aiming at the bottom of the blue insulators; 1 regular camera was kept on the East side of the module, also aiming at the bottom of the blue insulators. <br>

- started pumping down. <br>

Saturday, December 3rd: <br>

- 2nd HV test was done, with cameras' installed as mentioned above. results were consistent with the first test results. <br>

- added helium. results were the same. <br>

- vented and changed the location of the cameras: 1 regular camera taped to the UV camera were placed at the top of the Service Tray (South-West corner) aiming down the Service Tray; 1 regular camera was kept (its setup was not touched at all) on the East side of the module, aiming at the bottom of the blue insulators. <br>

- attempted to pump down, but the module was leaking. reopened the flanges, cleaned them, attempted again to pump down, but it showed a bigger leak. <br>

Sunday, December 4th: <br>

- the third attempt to pump down was successful (without reopening the module!). <br>

Monday, December 5th: <br>

- did the 3rd HV test with the cameras installed as described on December 3rd. same results as before were seen. <br>

- again helium was added and same results were noticed. <br>

- stopped pumps and prepared for venting to relocate the cameras lower in the Service Tray.

 

 

 

 Monday, December 5th (Con't): <br>

- vented and changed the location of the cameras;<br>

- the UV camera was placed (tapped on an aluminum spacer and on the grounded water lines) at the middle of the Service Tray (right below the first Mykroy insulator-plate) aiming down the Service Tray (at the second Mykroy insulator-plate and water lines) ; <br>

- 1 regular camera was placed right below the UV camera, also using a spacer (taped with the camera on grounded water lines) and also aiming down the Service Tray (at the second Mykroy insulator-plate and water lines);  The spacer for this camera had 300counts on it after it was removed from TM3, after the test;<br>

- NOTE: when installing the 1st regular camera: dropped a small allen key in the Service Tray. It landed on last insulator with the epoxi and water lines, between the first HV line and the wall of the grounded Service Tray.  This insulator is down below in the Service tray. Used a magnet stick to recuperate the allen key. <br>

- the 2nd regular camera was placed at the top of the Service Tray (tapped on the grounded water lines) looking down at the first Mykroy insulator-plate and water lines. NOTE: this camera had a filter applied to its lens. <br>

- pumped down <br>

Tuesday, December 6th:<br>

- did the 4th HV test with the cameras installed as described on December 5rd Tuesday morning very early . Same results as before were seen, except that the top camera (2nd regular camera) with the filter applied to its lens was flickering less than the other 2 cameras, and for small sparks this camera was not reacting at all. <br>

- vented shortly after the 4th test and relocated the cameras for the 5th HV test (last test); <br>

- placed only 2 regular cameras in the Service Tray;<br>

- 1 regular camera was placed right below the 2nd Mykroy insulator-plate, aiming down the Service Tray at the last insulator with the epoxi and water lines (this insulator is down below in the Service tray); <br>

- the 1st regular camera was placed a level up in the Service Tray, right below the 1st Mykroy insulator-plate, aiming down the Service Tray at the 2nd Mykroy insulator-plate; <br>

- NOTE: no spacers were used<br>

- pumped down and did the 5th HV test with the cameras installed as described above in the evening; <br>

- again same results as before were seen: the camera with the filter applied to its lens was flickering less than the other camera, and for small sparks this camera was not reacting at all. <br>

- NOTE: for this last test heard sparks outside (at atmosphere) when the HV was pushed at 26kV; <br>

Wednesday, December 7th:<br>

- vented and removed the cameras from TM3. No contamination was found on the cameras and wires. <br>

- TM3 was moved to the silo.<br>

 The concrete floor in the North Hot Cell service area and the top of the NHC roof block in the target hall have been painted with Macropoxy 646 oil based epoxy paint, colour Flint Grey.  Two coats were used for the NHC roof, and one for the service area floor.

  1413   Saturday, December 03, 2016, 10:01 David WangITWRepairTM2 venting ITW and TM2 with argon.

A short between TM2 EE and bias is produced yesterday during tube heater ramp up.  Alex asked for an argon venting on ITW to see if the problem could be solved by venting and pumping down yesterday.  I set up argon venting system in electrical room and started the venting at 8:30 AM this morning.  It will take 5 hours to vent the ITW to 760 torr(mechanical gauge reading).  The venting system pressure is set as 2 torr. A pressure relieve valve is installed into ITW venting line to prevent station over venting. The argon bottle  valve in electrical room will be closed by isac opps after 5 hours venting.
