Helium pressure test on TM2 all water circuits is done. 70 psi helium , 10 minutes test time. Leak detector :base leak rate 0.0XE-9 atm.cc/sec, base pressure 0.0Xe-4torr. No any response on LD during the test. All TM2 water circuit are leak free.

Conditioning completed over the weekend by RIB operations. The shutter was left closed on the module, so no beam could be seen on the FC. Conditioning otherwise OK.

Yesterday a leak was discovered in the ISAC-I experimental hall. The leak appears to be at the connection between the evaporator and the return water line. 1 in of water was lost from TCS:TK1. The water is currently valved off to prevent further leakage.

A fault reportt has been submitted to mechanical services - awaiting response.

Friday, November 01, 2019

Leak repaired by Mechanical Services. A brass fitting had cracked and was replaced with a galvanized fitting.

Thursday, November 07, 2019, 10:35: Tested source to 30 A on TGHT, TBHT and COIL. ANODE at 100 V.

Tuesday, November 12, 2019

The FEBIAD source worked well over the weekend. The anode current limit was adjusted twice to stop voltage limiting. About 5E-8 A on the FC with TGHT=580A, TBHT=300A, ANODE=200V,150 mA, COIL=50A. Bias was conditioned to 30 kV

Chad entered the NHC today to tighten set-screws on both slave side manipulators and re-align the West side slave. Work took place using the HC Confined Space Entry procedure. See attached checklist. WP I2020-02-27-4

Filters were replaced by Curtis von Cube on March 5th. See work permit for details I2020-03-05-5

Refilled TCS:TK2 from 10 in to 22 in using the newly installed valve.

Arthur installed a new Magna Power PS for the TGHT yesterday. The old power supply has been moved to Evaporator 2. The power supply was configured for remote operation and tested successfully with low current (30 A).

By Curtis. See Work Permit I2021-03-24-1 for details.

Adrian and co installed a new T to be able to add an instrument loop for O2 and pH monitoring on the low conductivity water systtem (photo). See WP I2021-04-09-4

Travis assembled and tested the steerer wires March 31st (see attached)

A contractor on site today for chiller maintenance. CP2 and CP3 circuit is leaking and shall not be used. CP1 can still be used. The contractor will contact Plant Group with a quote for repair and upgrades.

Tank refilled from 12 in to 25 in using the new valve.

The following controls-related items were installed for the SMP project:

- Cable tray

- Main control panel

- Motor starter box

- Wiring from limit switches and rotation motor to main control panel

- Air fittings at supply (quick disconnect)

- Main air supply hose from supply to control panel (quick disconnect)

- Air tubing from lid control valve at control panel to lid cylinders

Air fittings stem off existing air supply lines on the South wall, below a manual shutoff valve. A quick disconnect was installed. When SMP is not in use, manual shutoff valve should be left off.

Main control panel and motor starter box were mounted on the North wall. Wire duct runs from the main control panel to the grated floor. Cabling/air runs underneath the mezzanine platform, along existing and new cable tray, to the SMP.

Cable tray was installed on the South wall, from the corner to the SMP module. A cutout was made to accommodate for existing tubing. An additional ~1 ft. of tray will be added to the end, near the corner, at a future time.

Remainder of installation work to be done before commissioning:

- Mount and install new Opto-22 module
- Chain new Opto-22 module to existing one (power, comms) below mezzanine on North wall

TM4 has been moved from the South West silo to the South Hot Cell. New source tray, no target.

TM4 has been moved from the Conditioning Station to the South Hot Cell. No target.

TM2 was moved from ITE to South Hot Cell. Tantalum 58 target.

TM2 was moved from South Hot Cell to ITE. ZrC #8 target.
