  988   Tuesday, December 12, 2023, 16:11 Dave NeilsonShunt #0   -- P2N Thermal Test

Tuesday, December 12, 2023, 16:07  - Pumping down test stand overnight for testing tomorrow. vacuum good, turbos starting now. Four thermocouples attached inside. tc1: high on (+) TGHT leg, pins 1+2. tc2: at target terminal (+), pins 4+5. tc3: at target terminal (-), pins 6+7. tc4: low on (+) TGHT leg, pins 8+9.

 Wednesday, December 13, 2023, 09:32 : Vacuum at 8.2e-7 T.  Electrical team is finishing connecting the cables. Claim it will be complete at 11am.

 Wednesday, December 13, 2023, 11:41Started both tc loggers at 11:40 - important for offset time. Beginning ramp as well on ATTS TGHT. set vacuum values high at 1e3 1e4 to bypass ATTS interlock, which does not apply here. ramping to 600A with step increment 10A and wait interval 10s.

    ATTS TGHT claims ramping in progress, but increased voltage is reported only on the autoramp window, which reports increasing the target amperage by 10A each 10s. However, no increased voltage reading is reported there, nor is there any increased current. ATTS:TGHT:RDCUR and ATTS:TGHT:RDVOL are ~0 as well. No increased temperature on any of 6 tc channels.

Wednesday, December 13, 2023, 11:57 ATTS TGHT power supplies appear to be under local control. It also appears (low current right now) that the value reported in EPICS is 1/3 of the value reported on the master power supply. It may be that the epics value is per output of the individual 3 supplies, while the total output is reported on the PS display. Planning to now increase to 300A and reach steady state.

Wednesday, December 13, 2023, 12:13 : 1/3 ratio idea confirmed at 33A EPICS reading / 100A master reading and again at 100A EPICS reading / 300A master reading. 300A now reached. Waiting for 20min. Temps inside ~ 21°C. Temps on feed through terminals ~22°C

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.

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

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

  • While testing SiC#26 a leak was discovered on the water line to the heat shield. The leak was in the right joint (see attachment). The heat shield water lines were removed from the test stand and repaired in the Machine Shop. 
  • Kapton was added to the FEBIAD coil line to prevent it from shorting to the target heater line (see attachment).
