Blocks were moved from ITW to ITE by Frank and David. ITE water flow to dump was re-opened (ITW remains open). A dose badge was installed in the operation
storage area. Dose rates were measured to ~10 mSv/h at 1pm. Beam went off approximately 8:30am (with a short period of 2uA ending at 11am). |

|
Anders and I opened the HV cover in ITE and did a visual check inside ITE HV cover and top of TM3.Bill was with us and took the pictures.
There was nothing obviously wrong when we opened the HV cover in ITE. We disconnected TM3 high current cables from ITE. Then we did an electrical check
on TM3.The TM3 was good and passed megga test (465Mohm at 500V). The module was good and was separated electrically from the ITE at that moment. Then, |

MAA ASU test have been done following document 154779. All three tests in document are passed. DCR Jas has all test documents.
This test includes the functional test on TH emergency roof hatch which is located at the west end of TH roof. The hatch could be opened and closed
properly from TH inside. |

A special thanks to Kazuya, Jane and Ray who jumped on this issue right away! The limit of the BIAS PS was set as 20000uA when in reality it is
4000uA. The issue has now been corrected. Please remember to divide the current by 5 for any elogs older than this one. |

There is something wrong with the BIAS canbus controller. It says that it is not alive and has timed out. I have tried unplugging it and plugging
it back in but that has not resolved the problem as it normally does. I have contacted Dave Morris and am waiting to hear from him. I cannot HV test without
this controller. |

The crane pendant for the auxiliary hoist was upgraded to a FLEX EX2 style pendant by Canco Cranes. The installation work was performed by Canco, supervised
by Tom Kauss and David Wang. Installation work was performed in one day (I2021-03-26-1).

Tuesday, July 09, 2024, 16:14, Carla Babcock, ITE, Repair, , , Attempts to reduce ITE:EL trips from HV sparks 8x
|
ITE:EL has been tripping off due to HV sparks. Usually this also trips ITE:Q1/2. These are sitting in side-by-side racks.
The working theory is that HV sparks are returning to ground through the EL and quads, tripping them off. Possibly this is the result of a changed
low impedance ground path. How this change happened could be either something we did during shutdown or the changes we made in TM3, no clear evidence yet. |

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. |

Around 7pm tonight I opened the main valve approximately 1.5 turns on the Argon bottle used for venting ITE, located in the ISAC electrical room.
The cylinder pressure gauge increased to about 1500 psi. I adjusted the secondary regulator (pressure relief valve) until it read 2psi. I opened the
needle valve in the vent line completely. The pressure on the pressure relief valve dropped slightly and I adjusted it again until it read 2psi. The |

West target station is setup to use argon for tank venting. There is 1200 PSI remaining on argon bottle in electrical room. That is sufficent
for venting west target station to atmosphere twice. ISAC Operations has been previousily contacted and their procedures for venting remain the same
except that they can not rely on ITW:CG4S to determine when at atmospheric pressure. I have asked them to contact me if an unscheduled vent is required. |
