NEW HV cable for BIAS installed earlier this week.
Wednesday, June 28, 2017, 16:42: BIAS at 20 kV
Wednesday, June 28, 2017, 16:46: BIAS at 30 kV, EZL at 15 kV
Wednesday, June 28, 2017, 17:00: BIAS at 35 kV, EZL at 17.5 kV
The voltage response on TBHT and TGHT changed as the target was heated up. This was later determined to be due to target shorting to heat shield and the grounding of the power supplies being achieved at the HV pedestal in the target hall and not in the HV enclosure as is done online. When this was changed, the target operated normally again. |

Thursday, April 18, 2019, 10:04, Travis Cave, South Hot-Cell, Maintenance, , Ta#50, SiC#34, Ta#46, Ta#47, and Ta#45, Target transfer from old pail to new pail.
|
Targets Ta#50 and SiC#34 have been transferred from their old pails to new ones. Ta#50 was done on April 12th 2019 it was moved from pail #148 to pail #200 and a new field measurement was done and found to be 3.57mSv/hr. SiC#34 was done on April 18th 2019 it was moved from pail #143 to pail # 206 and a new field measurement was done and found to be 2.20mSv/hr. Both measurements were done by the RAM that is mounted at the south hot cell.
April 24 2019
Target Ta#46 has now been transferred to a new pail with a number 207 from pail 143 it was 3.62 mSv/hr when removed from the south hot cell.
April 25 2019
Target Ta#47 has now been transferred to a new pail with a number 201 from pail 137 it was 2.25mSv/hr when removed from the south hot cell. The bag that the target was in has shown signs of degradation.
Target Ta#45 has now been transferred to a new pail with a number 202 from pail 124 it was 1.45mSv/hr when removed from the south hot cell. The bag that the target was in was destroyed. Also in the pail was a shutter, IMG Gauge, some altem parts, wire and bolts.
The extraction electrode from Ta#47 was added to this pail as it was left behind from last transfer. |
