Hi Fernando,

  There are no plans for Cu-LCW system to be switched off today.  I believe they are still working on correcting the issue that caused the trip two days ago.  Once it is corrected and we are ready to switch to the secondary pump, the switch over "should" be relatively invisible with possibly a slight drop in line pressure.

Thursday, February 11, 2021, 13:42: Uncapable of holding HV. Maybe the new heatshield needs more time to outgas.

Thursday, February 11, 2021, 13:44: BIAS/EZL/EE @ 0.000 kV

Friday, February 12, 2021, 10:07: In order to trouble shoot the ISAC TS, I  let the sparks to continue. Initially, they occurred in the extraction electrode spark gap and were both visible and audible. However, they stop and the instabilitiy was present.

I rise the voltage again and let the spark happen for a longer period of time.

I saw how the collimator wire on the far back of the source tray was moving as if a hurricane was inside, which is very strange. I followed up the wire and I saw how it was sparking to something (see attached photo)

I say something because from the angle is difficult to say if it was going to the chamber itself or to the HS waterlines. Both scenarios are concerning

First of all the collimator is never biased and it if any case the jacket  (MHV cable) is on ground ground

In case the discharge happened from wire to the chamber, then the collimator wire was charging up, it is extremely important o note that the jacketed cable goes outside the box very close to one of the turbos.

In the other scenario where the discharge was happening from the wire to the HS waterlines, that is, HV to ground, the simply creating a clearance should be enough. In this case as well is relevant to know that this jackted cable leaves the farday cage.

I will create clearance from collimator wire to HS waterlines.

Friday, February 12, 2021, 11:05: Discharge confirmed visually to go into the HS waterlines, (HV to ground) (see second photo attached)

Friday, February 12, 2021, 11:06: Inside the blue rack,  I could hear ticks that match the discharges, probably  the collimator PS is there. Will check later with things  off.

Monday, February 01, 2021, 14:04: HV turned itself off, nothing tripped nor change. Not sure if related to the emittance scan that I was running. Setting it to zero before restarting it.

Monday, February 01, 2021, 20:14: Ramping things down and call it a day. My laptop charger broke and I don't want to leave the HV on.

Wire scanners look fine but the emittance meter was not working. Keiko soft reboot it but to luck.

Wednesday, February 03, 2021, 13:01: Spark. The HV bias voltage remained at 10 kV for several seconds. TSG:CBC was @ 2500 V. Likely, a sustained discharge towards the steerer had the HV bias power supply to get current limited

 Wednesday, February 03, 2021, 13:25: HV bias power supply gets current limited as of 15 kV. Setpoints to 0 to allow some discharge. Didn't work. Asking someone on site to have a look on the PS.

No sign whatsoever of a spark  to any device.

Wednesday, February 03, 2021, 18:27: HV has been erratic all day. Waiting for some stabilization allowed the system to reach ~24 kV. Now it has dropped to 20 kV.

Wednesday, February 03, 2021, 18:28: Increasing current limit on the bias PS from 0.015 to 0.02 mA

Wednesday, February 03, 2021, 18:55: Spark in the water lines. Current drop 60% from 0.03 to 0.01 uA. Spark observed in the GND electrode water lines

Wednesday, February 03, 2021, 19:11: Able to reach 28 kV but a spark ocurred.  TSG:CBC adn TSG:Q1 readback 2500 and 1500 V (similarly to the spark at 1 pm). Bias is current limited again, even at the new current limit.

• I think there might a short with one of the steerers cables, or a bit unlikely, to the quad.

Friday, February 05, 2021, 14:16:   BIAS / EE / EZL @ 30/ -1.5 / 13 kV.  Anode @ 50 V.

Friday, February 05, 2021, 14:18: Auto ramp-up TGHT/TBHT to 580/230 A @ 4A/min

Friday, February 05, 2021, 15:08: Anode shorted, I think the  tube heater is touching the plasma electrode. TGHT/TBHT @ 209/209 A. TBHT voltage= 2.2. At the same time the bias current jump from 0.008 to 0.01.

Friday, February 05, 2021, 15:12: Reducing the TBHT to 190 A 2 V. Bias current linearly reducing with tbht current. The cathode is not current limited anymore. Wondering if the TBHT power supply is causing an electrical backflow or if the ion source is touching the plasma electrode.

Friday, February 05, 2021, 15:16: Auto ramp-up TGHT/TBHT to 580/230 A @  2 A/min

Friday, February 05, 2021, 15:21: The same effect as before at TBHT=223 A. When reducing to 190 A, anode goes up. 

Friday, February 05, 2021, 15:30:  Auto ramp-up TGHT to 580 A @ 4A/min and TBHT to 230 @ 1 A/min. 

Friday, February 05, 2021, 15:55: Sparks, not audible nor visible. I think I saw one on the top part of the water blocks. Lowering bias to 10 kV.

Friday, February 05, 2021, 15:56 : Auto-ramp range to 4A/min on both TGHT and TBHT

Friday, February 05, 2021, 19:23:  almost 2.5 hours without sparks. RPM tests performed. Voltages to zero. Will rise later or tomorrow remotely.

Taped down to 180/500 A on TBHT/TGHT. All voltages to  BIAS / EE / EZL @ 0.000 kV.

Saturday, February 06, 2021, 11:14:   Auto ramp-up TGHT/TBHT to 580/230 A @ 4A/min

Saturday, February 06, 2021, 12:16:    BIAS / EE / EZL @ 30/ 1.5 / 0kV.  

Saturday, February 06, 2021, 12:30: The previous tune is not working anymore. I have to re-tune . EZL now helps to have a better tune, no need for extreme steering

Well well well, after several scans I observed the following:

• Bias readback changes by 14  V. This doesn't necessarily means this is the absolute value, it could be better or worse.
• Magnet oscillates around 1 gauss, enough to move the beam to the sides.
• Different settings on the rpm scans does not yield to different results in the data
• Intensity variations causes one of the rpms scans to be lower or higher.
• Total source scans are always mirrored as long as nothing else varies.
• Separated ion scans varied wildly. No two consecutive scans are the same. Likely a combination of Bias voltage and magnet current ripples.
• Following Baartman's proceedure on a cherry-picked data set, I estimated an energy spread of 11.75 eV. To be discussed with him

Saturday, February 06, 2021, 20:00 Biases to 0.000 kV

Saturday, February 06, 2021, 20:00 : Auto-cooling TGHT/TBHT  to  400/150 A @ 3 A/min

 Saturday, February 06, 2021, 21:02: On the way down, TBHT 150  A and when TGHT cross 480 A the anode came back to life. Wonder if this could help diagnose deflection on the surface ion source (might be helpful for the P2N)

Sunday, February 07, 2021, 08:26:  Auto ramp-up TGHT/TBHT to 560/210 A @ 2A/min

Sunday, February 07, 2021, 09:18: Anode got current limited again when TGHT/TBHT @ 446/200 A 

Sunday, February 07, 2021, 11:26:  Auto ramp-up TGHT/TBHT to 560/210 A @ 2A/min 

 Sunday, February 07, 2021, 11:31: Once again, the latest tune did not work. I suspect the ion source deformation varied from thermal cycle to thermal cycle. With a crooked beam, the EZL will send the beam off-center and the quad will not compensate that. The double peak observed in the beam size scan indicates that the focusing is not correct.

Sunday, February 07, 2021, 18:41: With Baartman RPM scans, the x axis in in cm, as verified with an emittance scan.

New parameters on the emittance rig for this tune. Offset from 40 to -50. This shifts the phase space in the y axis such that is visible on the plot. 

Even in a different mass, the position scans on the dispersion plan are not reproducible.

Sunday, February 07, 2021, 18:52: Auto-cooling TGHT/TBHT to 400/150 A  @ 6A/min / 3 A/min, respectively.

 Sunday, February 07, 2021, 18:53: Biases to 0.000 kV

I think the fast cool-down rate prevented the TBHTto be able to sustained voltage.

Sunday, February 07, 2021, 19:35: Auto-cooling TGHT/TBHT to 0 A @ 3A/min 

TBHT able to sustain voltage once TBHT=191 A and TGHT=372 A

After inspecting the ion source, and revising the electrical connections, I suspect that the TBHT was floating all the time and only when it was in contact with the plasma electrode it held HV.

When the plasma electrode was removed, there was no reference whatsoever, and the ions were not extracted.

It seems then that the resistor R4 (ISK4562D) is necessary to provide a reference to the TBHT  in a similar way R1 provides one to extraction electrode.

Tuesday, February 09, 2021, 20:52: Installing R4. If the anode works this time, it will be worth checking why this reference is necessary. From the electric diagram, the chassis ground should be HV ground.

Using a broken LP-FEBIAD source. TGHT only.
