|
Target Ionizer tube cooling lines "C" and "D" in Target Module 2 were both leak checked at the Hot Cell. The lines were both
blanked-off.
Bill Paley was present with David Wang in the Target Hall, operating the leak detector. Grant Minor and Anders Mjos were present with Chad |

Wednesday, October 14, 2014
The BIAS voltage was brought up between 1:30pm and 5pm. Sparks tripped the BIAS power supply at voltages between 20 - 24 kV. Multiple attempts
were made. The current was about 50-60 uA. |

|
Wires for TM#2 steering elements, and png gauge have been run down to the containment box level. Chad has placed them in the little cable trays. Slack
has been pulled back. and termination of the wire will be done on the 7th of May. A modification was done to the signal line of the png gauge wire ultem
block, as grounded screw was inserted to allow for strain relief so the end would hopefully quit breaking. See attached pictures for the details. |

50 kV stable with less than 1 spark/h during the weekend by RIB obs.
Today 57 kV reached, but observed sparking on the resistors of the new HV cable. The cable will be removed to take out the resistors, before reinstalling
it. |

Conditioning continues today with resistors removed from the HV cable
Tuesday, July 18, 2017, 16:53: BIAS / EZL 50 / 25 kV - no sparks

|
Frank and Anders installed lid on TCS and started vacuum system yesterday. To run over the Holidays. Retrieved dose badge from operational storage area.
Measured field to be ~ 10 mSv/h at ~9am. Beam went off about 8:30am. |

|
TM4 in conditioning station with no source tray, extraction electrode set to HV bias. Brought up to 30kV over the weekend by ISAC ops with no issues.
BIAS=30kV
EL=15kV |
|
Monday, June 10, 2019, 16:22, Carla Babcock, Conditioning Station, Maintenance, TM4, No target, Ramping V on TM4, no HV cover in TH
|
Ramped down the bias so David could remove the HV cover and lock out the target hall.
Ramped back up to BIAS / EL = 50kV / 26kV quickly with no sparks.
Monday, June 10, 2019, 15:35 : BIAS / EL = 52kV / 26kV |
|
Monday, June 10, 2019, 18:12, Carla Babcock, Conditioning Station, Maintenance, TM4, No target, Attempt to push bias > 56kV
|
Monday, June 10, 2019, 16:59 : TM4 back up to BIAS / EL = 56.1kV / 29.5kV
Monday, June 10, 2019, 17:14 : After 57kV on the bias, things seem to be getting sketchy. The EL voltage and current are a bit jumpy and stepping
that voltage up seems to produce a slight spike in the bias current. |
