David Wang | Conditioning Station | Standard Operation | TM2 | | Helium pressure test on TM2 window and HS water lines at TCS. |
I did helium pressure test on TM2 containment box window and HS line at TCS. @ 70psi helium for 3 minutes, HS:2.2XE-7 atm.cc/sec., Window:1.2XE-7 atm.cc/sec. There is no change on HS. But LR on window is bigger than before that was in E -9atm.cc/sec range. |

Anders Mjos | Conditioning Station | Development | TM2 | | Changes to MP3 startup |
Due to problems with the regulating valve WPV1, the VFD (Variable Frequency Drive) for the pump has been programmed to do a slow (2 min) ramp up. WPV1 has been bypassed and left fully opened. Work was done by Dave Morris |

Cooling water not yet connected to TM.
High leakage current still observed. 200 uA at 22 kV. Did not go past 25 kV.
Friday, September 29, 2017, 14:05: Started heater ramping to 580 / 200 A at 1 A/min
Friday, September 29, 2017, 14:09: BIAS / EZL / EE at 20 / 10 / 1.5 kV. BIAS current at 90 uA
Monday, October 02, 2017, 10:29: Accidentally set BIAS current limit to 0 A (step size too large) at 28 kV. This also caused the TGHT to got to 0 A. Recovered to 580 A in 10 - 15 s.
Monday, October 02, 2017, 12:07: Ramping down heaters at 2 A / min |

David Wang | Conditioning Station | Repair | | | Re-route TCS water lines. |
TCS cooling polyurethane lines have been re-routed to solve to HV sparking issue on old configuration between lines and bais plate. New re-routed system is tested to 70KV without spark. No leak has been found on new lines after the test.
ECO 4369, drawings and models IRH1715, IRH1716 have been issued and released for this job. Drawings and Models are located in PDM-ISAC1 -TCS polyurethane water lines re-route folder. |
