Monday, November 27, 2023, 16:09  Roughing

Monday, November 27, 2023, 17:22 Both turbos are on, leaving vacuum over night.

Tuesday, November 28, 2023, 09:28  after pumping over night IG1 is at .15e-6 T. Water cooling on.

Tuesday, November 28, 2023, 14:34  HV test started. Sparks on the TC seen at BIAS/EE/EZL 31/-1.8/15kV. TC values recovered after sparks, TP6 tripped during sparks as well. Venting chamber to reposition TC.

Tuesday, November 28, 2023, 17:37 I couldn't manage to close properly the side door of the chamber... waiting for help tomorrow.

Wednesday, November 29, 2023, 10:51 Roughing started earlier in the morning. IG1 at 1e-5 T. Ramping up bias.

Wednesday, November 29, 2023, 11:41 HV tests lead to 45kV sparks on the TC. Nothing seen on the RPi.

Wednesday, November 29, 2023, 13:22 The ballast of TMSRP2 was opened to attempt to improve the roughing in the beam line section. Things appear to be somehow better now, TMSTP6 and TMSTP2 are on now.

Wednesday, November 29, 2023, 16:00 IG1 is at 3.58e-6. HV tests starting again.

Wednesday, November 29, 2023, 23:36 HV tests ended earlier in the afternoon. No spark up to 55kV when gauge in the HV cage started sparking as usual.

Wednesday, November 29, 2023, 23:38 TGHT and TBHT ramp up in preparation of mass scans in the morning. 1A/30s up to TGHT:400A, TBHT:160A

Thursday, November 30, 2023, 09:05  TGHT and TBHT ramp up in preparation of mass scans in the morning. 1A/30s up to TGHT:580A, TBHT:230A

Thursday, November 30, 2023, 12:12 Mass scans started earlier in the morning. 1st scan completed at 0.1A/s, repeating it again now with 0.05A/s.

Thursday, November 30, 2023, 15:04 HV tests again up to 55kV. 2 sparks inside the vacuum, to be checked if they affected TC measurement with the pi. Gauge still sparks in the upper HV cage.

Friday, December 01, 2023, 12:05.  Error saving mass scan data Thursday. Repeating mass scans at 0.02,0.01,0.005 scan speeds. note* must delete old data prior to saving. -> save procedure: Delete Old Data, Right click plot, save as plot.txt, click Clean, Show/Save Data, enter file name and save. Filenames: 2023-12-01-* 

Friday, December 01, 2023, 15:22.  Spent some time selectively tuning various elements of the beam. Report in local folder, file "2023-12-01 beam tuning".

Friday, December 01, 2023, 15:23. Recording mass scan with inactive quadrupole elements. File name 2023-12-01_Q-off.txt

Sunday, December 03, 2023, 22:02 : Vacuum looks good.  4e-7 T.   Heating up target for Monday morning. 1A/30s up to TGHT:580A, TBHT:230A

Monday, December 04, 2023, 12:21: This morning, increased BIAS to 30kV. Ran mass scan with adjusted beam tune up to FC0. This mass scan was repeated with inactive quadrupole elements up to FC0 to compare with Friday.  2023-12-02_RBsalt_SIS_test1.txt and 2023-12-02_RBsalt_SIS_test2.txt

Tuesday, December 05, 2023, 14:12 HV tests restarted, TC wire brought closer to the ground wall. IG1 at 2.3e-6 T. Ramping up HV.

Wednesday, December 06, 2023, 13:48 Both yesterday and today the TC wire was not close enough to spark even at 60kV. Venting the chamber one more time to bring the TC closer. 

Thursday, December 07, 2023, 10:18 Vacuum at 5e-7T we see sparks at about 47kV. Lost control of epics during sparks, PS shut off manually. Everything recovered after.

Thursday, December 07, 2023, 13:32 After spark tests at ~55kV, Pi seems not to be affected by the sparks. Tests without the power surge components yielded similar results. We discovered that the sparks on the TC are partially diverted by spark gaps and probably other elements in the top HV cage.

 Monday, December 11, 2023, 10:35 Turbopumps winding down.

HV conditioning has begins. Vacuum chamber pressure is currently 3.2e-07 Torr on TSG:IG1.

Did HV conditioning up to TSG:BIAS=30kV, TSH=EE=-600V

Turned off the HV for Kazuya to check the connection/output of the TSG:TGHT Xantrex power supply.

Started the HV conditioning: TSG:BIAS=30kV and TSH:EE=-700V.

Started the HV conditioning: TSG:BIAS=30kV

Started March 31, 2014:

- did the HV conditioning up to 30kV.

April 1, 2014:

- started the Heaters Conditioning. 

Heaters Conditioning finished.

The Power Supplies front panel:

TGHT: 5.56V and 580A

TBHT: 2.23V and 227A

April 2, 2014:

- did a mass scan. NOTE: data is shifted by 10-15%.

plotdump-local-clean.txt_Apr2_14_16-33-19.txt

After the scan finished I found the Test Stand EPICS screens whited-out. Decided with Friedhelm to leave it as it was for the night and to contact Controls next day to reboot it without tripping the heaters and the HV.

April 3, 2014:

Found everything recovered. Except: “SOURCES ARCH IS RUNNING” was red. So, I restarted it. Jane Richards and Friedhelm didn’t do any IOC reboot. Also found that the data from yesterday’s scan was saved (see the previous scan).

Did another mass scan:  plotdump-local-clean.txt_Apr3_14_10-18-13.txt

NOTE: data is shifted by 10-15%.

Cooling down .

HV and Heaters Conditioning had finished. The target was cooled down and it's ready for the on-line installation.
