Tuesday, November 04, 2014, 11:05, David Wang, South Hot-Cell, Standard Operation, TM1, ThO#1, Leak check on TM1 HS water line withThO#1 installed.
|
Chad and I leak checked HS line on TM1 with ThO#1 target installed. The LD pumped down to base leak rate 0.0xE-9 atm.cc/sec, base leak rate 0.0xE-4 torr. The pumping down process is normal. Chad sprayed helium on both VCR joints (each for 2 seconds) , and he did a flush spray around the target for 5 seconds. No any response had been found on LD during and after the spray( 40seconds waiting time). The target is leak tight. |

Monday, October 20, 2014, 09:13, David Wang, Conditioning Station, Development, TM3, , TM3 TP2 failed
|
TM3 TP2 stopped working this morning at 4:00 AM. I tried to start it but failed. On normal start mode , It could not pass 6K RPM. On soft start mode , the pump cant pass 17KRPM. Talked with Anders, We are not going to replace this pump since we are not going to run this module for a while. I will stopped all vacumm pumps on CS and TM3 this morning. |

Monday, October 20, 2014, 08:59, David Wang, Conditioning Station, Development, TM3, , Started TCS water system.
|
I started TCS water system this morning to check if the chillers work properly. |

Friday, October 17, 2014, 13:36, Anders Mjos, Conditioning Station, Maintenance, , , TCS:Chil staging not operational
|
NOTE: If cooling is required, the compressors will have to be run manually. Make sure to switch it off again when the water has reached an acceptable temperature.
The staging did not work properly this morning. Dave Morris have been contacted and will look into it. |

Thursday, October 16, 2014, 15:40, Anders Mjos, Conditioning Station, Maintenance, , , Chiller unit
|
NOTE: If there is a problem with the chiller unit (ie Fault 1 or Fault 2), a power cycle may reset the VFDs for the fans and clear the problem. To do so it is necessary to wait long enough for the VFDs to power off completely. The display will first start to flash before going dark. Wait another few seconds before powering the system back up. The chiller unit is located on the ISAC I Penthouse Roof.
A service tech from Daikine was on site today and has cleaned the chiller unit. In the process he also cycled the power which returned the operation back to normal. The tech provided us with manuals for the VFDs. These can be consulted on DocuSharefor looking up error codes.
Fault 1 refers to unit 1 and Fault 2 to unit 2. |

Tuesday, October 14, 2014, 17:19, Anders Mjos, Conditioning Station, Standard Operation, TM3, No target, High Voltage Conditioning
|
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.
Wednesday, October 15, 2014
Temperature in the cooling circuit is too hight to do a HV test. The cooling circuit was started, but shuts off after ~10 m
Thursday, October 16, 2014
David and I found that the fans on the cooling unit on the roof did not run and that the compressors get hot and likely trip on over temperature protection (hot to the touch). We found the manual in the control panel of the unit.
10am: HV to 20kV before a spark tripped the PS. Current at 40 uA - resistivity at 11.9 Mohm
5pm: HV to 20kV before fluctuations in current, then a spark tripped the PS. Current around 40 uA. Resistivity 12.6 Mohm
Friday, October 17, 2014
8am: Staging did not start over night. TS5 temp is 31 deg C, which would have tripped power supplies. Reset and enabled staging.
The system increased staging until all 3 compressors were running.
9am: Cooling supply temperature reached ~3 deg C. Disabled staging and switched off all pumps
2pm: Switched off water circulation for the weekend.
