Frank and Anders installed lid on TCS and started vacuum system yesterday. To run over the Holidays. Retrieved dose badge from operational storage area. Measured field to be ~ 10 mSv/h at ~9am. Beam went off about 8:30am.

Bevan and I installed 2 turbo pumps on TM2. The o- ring flanges on TM2 had been cleaned before the installation.

David installed the new ball valve and connections for the SAS project module move ventilation. SASP0482. Drawing reference ISK5029B.

Installation by Marshall. Dave M from controls adjusted circuitry to get TCS:MP1 to start.

Work is being done in preparation for the Module Move Ventilation SAS project

 Installation of of operator-level lighting in the NHC was completed today according to drawing IRH1801.  2" x 2" Panduit was mounted to the wall on aluminum brackets to support the power cables.  These lights can be replaced remotely by unplugging the power cords using the manipulators, lifting the cable out of the Panduit with a hooked pole tool through the manipulator slave end removal roof hatch, lifting the light fixture off the support bracket with the pole tool, then installing a new fixture in the opposite order.  This RH procedure will be tested at a later date as part of NHC commissioning.

Shielding plug is installed onto TCS. TCS is being pumped down to keep it under vacuum for the rest of the year.

I installed a set of new high current cables for TM2 Febiad run. The top of TM2  is configured to Febiad mode. See attachments

Tom Kauss inspected target hall crane below hook attachment pins and plates ITA6550-01 yesterday. He certified the use of these pins and plates for year 2024. The inspection of these pins and plates was in Target hall crane annual check list. It was issued as a calibration index by Isaac Earle in 2022-Feb-08.  After inspection, The inspection tag  was issued and attached to pin. Tom has an inspection record on this job.

Tom Gauss inspected  two target module lifting frames ITA0494-1997-01 and ITA0494-1997-02 yesterday. He certified the use of these two frames for 2024. Inspection tags have been issued and attached to frames. He has inspection record on them.

Inspection of TaC#1 showed that the oven was indeed broken on the A+ (left oven leg) side of the central block.

TM3 and UCx#44 ran in ITE but issues with the cyclotron prevented proton beam delivery. Nonetheless, the target was heated and provided stable beam to TITAN as well as for tuning and some tests.

Results of inspection of TM3 module after run:

The module looked pretty good. There were no marks on the polished surface of the containment box, next to the water blocks, that were visible. But we didn't remove the box, only looked with the camera and it was visible by turning the module. So some things may have been hidden. There were some black marks on the door, near the bolts that hold in the handle (see attachment). This seems a very unlikely spot for sparking as the fields should be considerably lower than at the target handles, lower down. Maybe the spots are from oil left on the door that had a chemical reaction? There is one very faint matching spot on the top of the copper trident connector, but it doesn't look much like a spark mark. The other two marks have no corresponding mark on the source tray. There were no marks on the ground electrode, or anywhere else on the source tray. There was a scuff on one of the trapezoidal insulators, but it could have happened during installation.

Results of inspection of the target after run:

The FEBIAD target developed the same cathode short we have seen on almost every FEBIAD we run online - a high resistance short from cathode to HVC that prevents voltage on the cathode. This time the short remained after cooling the target, and David measured 208kOhms with the ohmmeter on the module top (11kOhms with the megger). We used a multimeter in the hot cell to test after the target had been dismounted and we found no short. So it must be related to either the position of the target (upright vs face down) or time (a conductive trace on an insulator oxidizes and becomes non-conductive again) or some pressure/shaking during the de-installation.

There weren't many marks on the target - a faint mark near where the faint mark on the copper trident was observed, some marks on the EE which had no counterparts on the ground electrode. See pictures.

Chad and Anders inspected the Source Tray today using the camera in the hot cell. A dark spot was observed on one of the four insulators separating the Extraction Electrode from the Ground Electrode. This could potentially influence the high leakage current. Some discolored areas were also observed in the Service Tray, but these was present when the module was built. See attachment for details.

Yesterday, Grant entered the Ante Room with David Wang to visually inspect the two sets of failed c-seals from the Heat Shield circuit, to remove the second set from the Heat Shield water blocks, and to leak check the heat shield circuit with o-rings and a water-block-to-leak-detector fitting.

Some photos of the inspected seals are in the attached design review presentation.  Some unusual marks were observed on both sets of failed seals.

The heat shield lines and water block assembly leak checked successfully to the bottom of the leak rate range ("UNDER" ~1x10-9 atm cc / sec on the Varian 979) with a great flood of helium on all joints with no response anywhere.

The in cell airline has preemptively been replaced. The hose was, as far as I know the original.

Air leak was found at the Solenoid control valve located in the Pre-Separator & DB0 room.  The gasket between the solenoid body and its manifold block was broken, see attached photos. The gasket and solenoid body were replaced. Air was turned back on to IV5 (B/L gate valve) with no apparent air leaks. The gate valve was actuated open & closed from the control room seeing both limits successfully.

Measured resistance on safety limit switches for FC5 on Exit Module 2. Determined that the in connected signal did not work (shows not connected irregardless of FC position). Confirmed proper operation of the OUT limit. See attachment for details. The Harp 5 x and y signal connectors were checked and reconnected.
