Target needs to be removed form teststand to remove heatshielding around target oven. The chamber will be vented, water circuits flushed and target removed. |

|
A chip of insulator material was detected below the lower target insulator stand-off (attachment - left picture). The chip may come from the tube heater insulator above (attachment - right picture). The chip will be further investigated when the target is removed. |

|
Today: did a mass scan at 580A on TGHT and 230A on TBHT at 30kV. Found some A/q units discrepancies on the mass scan page. It may be a hall probe problem: under investigations.
Uploaded the testing file on Docushare: http://documents.triumf.ca/docushare/dsweb/View/Collection-8539/Document-56575
Started the cool down. |

|
During the mass scan today it was discovered, that the mass calibration was off. Further investigation showed, that the Hall probe readings are a factor of 1.31 lower than during previous measurements. A fault report has been issued to controls. |

The chip came from the lower insulator stand-off on the target assembly (see attachment). After investigating the chipped insulator, it was decided (Pierre, Friedhelm, Anders) not to replace it - as the risk involved may be less than the risk involved in replacing. |

Did the HV conditioning.
Heaters conditioning in progress.
The Hall probe is not working: couldn't pass 35.5 units (readback) or 50.16 units (setpoint) at field -3710G.
Tried to turn ON/OFF magnet PS and to reboot Canbus, but nothing worked. Still waiting for E-Fault 6031 to be resolved.
Started cool-down. |
