Target-tube cooled down over night. Will went to investigate TC connections.

Wednesday, January 22, 2014, 08:38 : Turbos stopped. Vacuum at 1.3E-7 T

Opened the ATTS, placed what I will call “Cast Alumina Sample #1” into the ATTS and activated the roughing then turbo pumps. Currently sample is in slow heating progress to 1000 degrees Celsius, process is expected to take some time, so I'll revisit after lunch.

Started the heaters conditioning: TGHT up to 580A and TBHT up to 230A.

A major leak was found on the connection to the regulation valve on the He bottle. Ferrule replaced. System leak checked.

After He bottle: base 5E-6, no response to He spray

AfterSV1: base 5E-7, no response

After SV2: base 4E-7, no response

The system should now be operational. Gas lines were evacuated with the leak checker.

New supply of He and Ne was installed yesterday and gas lines leak checked. The He bottle is currently closed.

UPDATE Monday, June 17, 2013, 15:17

Specifications for the currently installed Ne leak (SN: 11-231) can be found on DocuShare

During the mass scan today it was discovered, that the mass calibration was off. Further investigation showed, that the Hall probe readings are a factor of 1.31 lower than during previous measurements. A fault report has been issued to controls.

Jens Lassen provided a new controller for the Hall prove. With the help from Graham from controls it was reconfigured and is operational again. The magnet must likely be calibrated again.

New calibration of the m/q based on the hall probe after exchanging the controller(MASSOVERQ2). Based on NiO#2-HP-FEBIAD with Ne supplied and ANODE biased to 200V, 30kV Bias.

CONST11 = -16.3929

Tuesday, October 31, 2023, 14:39 IG1 5e-6Torr , TGHT ramp up on hold.

Tuesday, October 31, 2023, 14:40 Starting HV tests.

Tuesday, October 31, 2023, 15:10 HV tests went up to 53kV until gauge on Faraday cage started sparking. TP6 seems to have tripped after a few sparks from that gauge. The TC wire seems to be placed to conservatively.

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.

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.
