The cyclotron radiation survey was aborted due to the orbit not working recording the numbers correctly. One shield has been in installed.

Jan 29th: uploaded meeting minutes from January 28th regarding the orbital counter problem. - Grant Minor

200's, 400's, 500's, 600's, and a pallet of 700's have been installed

All shields, pothole covers, and ladders have been installed into the cyclotron.

Started on the removal of shields.

More shields have been removed from the cyclotron only 16 remain. I was also noted that the lift trolley is making an odd noise and will be looked at after the shutdown.

all shields, porthole covers and ladder out and copper blockers in. Some conmination was found on the pads of the ladders (about a 1000 count or so) and was removed.

all 200, 400, 500, 600, and some 700 series of shield are in.

All shadow shields have been installed. Ladders, the pothole covers and the second rad survey will be done tomorrow.

All cyclotron in tank work is completed.

outrigger 1 had a power failure, bridge was removed power restored and outrigger parked, outrigger will be looked at once the shield are done hopefully.

The festooning and bearings for the festooning cars for both outriggers has been replaced and it is in working order.

An issue was observed in which radial motion on the Video Trolley Mk 1 did not respond to commands. After troubleshooting, it was determined that this was due to the "OP LIMIT" interlock - the "OP LIMIT" pushbutton on the console was illuminated in red, and needed to be continuously held down in order to operate the radial in/out motion buttons.

It was determined that the root cause of the issue was a failed radial limit switch which was likely damaged during trolley transport. The limit switch was replaced, and functionality was restored.

All control to the video trolley was lost during remote photographing of components in the cyclotron. The control system and cameras on the trolley were still operational leading to the suspicion that a power cable was broken either on the trolley or the bridge festooning. Two trips into the tank were made to evaluate the problem and attempt to push the trolley out of the tank. Pushing the trolley only managed to move the trolley a few feet before jamming. A lift mechanism was used to raise the drive wheel without any success. This device was modified and used successfully to remove trolley completely from the tank.

The vault crane annual inspection was completed by Tom Kauss.

The wired pendant was replaced with a remote pendant by Tom Kauss.

The vault shield door has been closed and seal inflated. The operation was performed with no issue.

The two support fingers on the upper resonator trolley were bent due to excessive loading during cylinder toggling.

Fingers were bent back into position such that they are vertical when the cylinder is retracted.

The cylinders used to actuate these fingers were replaced (one was leaking) - replacement allowed for the opportunity for upgrade. The following changes were made:

• Changing reverse spring-return cylinders to double-acting cylinders (formerly American Cylinder 750RVS-2.00, replaced with SMC NCDMB075-0200C)
• Addition of in-line flow controls for both extension and retraction motions
• Tuning of flow control to achieve smooth operation and prevent further damage to the fingers during actuation

 The new finger configuration has been tested and is working.

 24 Month, 60 month service completed. Bearings for drive motor wheels regreased and observed to move freely without load. Reducers repacked with Molub Alloy 777-1 ES. Vertical ball screw mechanism inspected and bearing change postponed due to lack of major usage, recommend change within next 5 years or service. All mechanically sound.
