Tool Trolley:

The connector faceplate was replaced with a new version to allow for more space for service, and consolidate video lines into a single 9-pin CPC connector. A model and drawing were created and are part of the overall tool trolley assembly (to be added to PDM later): TRH1394

Air tubing that previously ran to the connector faceplate on the tool trolley was replaced as it was very old. New tubing is in 3 different colours for easy identification: blue, black, green.

Fittings were replaced with more modern push-connect style (1/4" tube).

Prior to commencing work on jacking stations we installed a wall mounted come along plate as per Jason kapalkas instructions   Completed spare jack swap on station 11 and 12, station 11 was swapped with spare set # 13 and station 12 now has # 14 jack set in its place. Once jack stations where swapped we proceeded to clean, inspect and re grease 11-12 upper bearings.

 The Blue Shield Door on the B2 level of the RH building has been closed.

On January 8, 2018, while troubleshooting the Cyclotron Elevating System during the lid-up operation, the
insulation on the three motor drive wires were repaired (w/ electrical tape) and the two motor brake wires were
replaced (w/ crimped butt splices) between the horizontal conduit below the Cyclotron and the terminal block on
the Station #9 motor. The wiring was severely damaged over an 18" long interval that crosses the mid-plane of
the Cyclotron; outside of the 18" damage zone, the wiring insulation was ductile and showed no signs of cracking
or embrittlement.

On February 22, 2018, after the in-tank work was completed and the lid was lowered, the wiring for the synchro
and bump switch on Station #9 was pulled for inspection, which revealed that the insulation on the five synchro
wires had almost completely disintegrated, and the insulation on the six bump switch wires appeared to had
melted together to form a single wire over the typical 18" interval that roughly corresponds to the gap between
the Cyclotron resonators.

On February 23, 2018, the three motor drive wires on Station #9 were pulled and replaced, using crimped butt
splices to the existing wiring in the horizontal conduit below the Cyclotron, as the electrical tape repair job
during the lid-up operation was only a temporary fix. Also, the motor drive, motor brake, synchro, and bump switch
wires on Station #3 were inspected and replaced due to insulation damage.

On February 27, 2018, the synchro and bump switch wires on Station #5 were inspected and replaced due to insulation
damage. The motor brake and drive wires were inspected and re-connected as the insulation showed no signs of damage.

We had just finished pulling out the ladders from the cyclotron with the lift trolley. We started to run the lift trolley into the cyclotron when it stopped moving. The radial drive gearbox was the problem. We pulled the gearbox off. Replaced  the key and the lift trolley is all repaired.

Lower resonator trolley radial motor overcurrent was causing control system to drop out momentarily.  All controlled devices acted as expected and reverted to their fail-safe mode.  When system restarted 1-2 seconds later, all solenoids returned to their previous positions.

The cause was eventually traced to an unusual operation of the trolley.  In an attempt to limit trolley motion the drive switch on the control panel was repeatedly “tapped” in a rapid fashion.  This did not allow the motor to slow down enough to allow the starter winding to kick in which allowed large in-rush current.  The current was enough to load down the entire system including the power supply for the trolley controls, which caused the controls drop-out.

Later the same effect was observed to a lesser extent on the upper resonator trolley which used identical motors and controls.

Proposed solution is to either to limit large inrush current or preferably to replace the existing motor with a DC motor and controller.  A DC motor has the added benefit of now allowing true speed control.

No attempt is being made to modify the system until after the shutdown.  All trolley operators are being instructed to not use this method to attempt to control positioning of the trolley.  It is unlikely that it would help in positioning even if the system could handle the current overload.

 HE1 probe was reinstalled in the cyclotron this morning as per the procedure in Document 126165.  Hardware for the probe head motion had been repaired/replaced by Probes Group, so the probe head could be put in the fully retracted position.  The job went smoothly and nothing unusual was encountered.

 The HE1 probe was removed from the cyclotron today using the procedure in Document 126165.  The reason for removal is so that Probes Groups can attempt to repair a problem with stuck probe head drive.  Due the failure, the probe head was almost at the inboard travel limit (towards cyclotron center post) at the time of removal. Additional cut-outs were added to the HE probe frame to accommodate the probe head and ribbon cable wheel which were not at the normal position.

Location of the frame below the probe was done according to the procedure.  While moving the frame up some resistance was encountered about 1" from contact between the frame upper surface and the base of the probe.  After some investigation with outrigger cameras and direct viewing from the tank edge it was determined that the probe head was interfering slightly with the removal frame.  The probe head was driven completely to the inboard limit (a small amount of travel was still possible).  After moving the probe head the frame could be raised up to the probe without issue, and then it was removed from the tank as per the procedure.

The probe is scheduled to be reinstalled next week after the repair is complete.

 All cyclotron in tank work has been completed.

Remote Handing is ready for January, 8 2018 Cyclotron lid up. Elevating system service has been completed.

A Cyclotron Lid raise was attempted on Monday, January 8 at 12:00, however this attempt was aborted after lifting the lid several millimeters due the motor
brake on Station #9 that would not release properly. After troubleshooting the elevating system for several hours, motor brake wires were disconnected from
the motor terminal block at the station and pulled through the vertical conduit down the B2 level below the Cyclotron for further inspection. The inspection
showed severe damage to the wire insulation and conductor over an 18" interval, which corresponded to the position directly across the mid-plane of the
cyclotron. New wires were spliced to the existing wires at the bottom of the vertical conduit section, which were run through the conduit and reconnected to
the motor terminal block.

The motor drive wires on Station #9 were also removed for inspection, which revealed major damage to the wire insulation over the same 18" interval;
however, the conductor remained intact and was covered in electrical tape and re-run through the conduit vertical and reconnected to the terminal block. The
elevating system was then tested and the motor brake on Station #9 released as expected.

The Cyclotron Lid was successfully raised on Monday, January 8 at 20:00. The initial station readings are shown below:

A simulated removal of a lower resonator from the Cyclotron tank was attempted by the RH group using the 
service bridge, lower resonator trolley, lower resonator attachment, and the (soon to be) attached lower 
resonator removal procedure on 2017-02-27. Prior to aligning the attachment over a lower resonator, a small 
piece of paper debris was observed falling off the trolley. A successful recovery operation was performed using 
the vacuum trolley; however, the lower resonator exercise had to be abandoned until a future shutdown due to 
scheduling constraints.

A simulated removal of the LE2 Probe from the Cyclotron tank was performed by the RH and Probes group using the 
service bridge, upper resonator trolley, LE probe attachment, and the (soon to be) attached LE Probe removal 
procedure on 2017-02-23.

The unshielded radiation survey was performed in the Cyclotron tank by the RH group using the service bridge, 
tool trolley, and radiation survey attachment on 2017-01-30 (see attached plot).

The shielded radiation survey was performed in the Cyclotron tank by the RH group using the service bridge, 
tool trolley, and radiation survey attachment on 2017-02-02 (see attached plot).

A obsolete version of the radiation survey procedure (from Don Jackson) that needs revising and the MATLAB code 
for generating a radiation survey map (from Maxim Kinakin) is attached.

The start of shutdown photo and video survey was performed in the Cyclotron tank by the RH group using the 
service bridge and video trolley on 2017-01-27 (see attached pictures).
 
The end of shutdown photo and video survey was performed in the Cyclotron tank by the RH, Probes, and 
Operations group using the service bridge and video trolley on 2017-03-08 and observed the following:
- Observed a small piece of melted plastic and wire near the 180° lower tank D-gap; this item has been present 
since the 2016 shutdown based on photographic evidence (see attached picture).
- Observed a large strip of paper on Q2L2, close to where the ladders were placed beside the CP (see attached 
picture). 
- Observed a bent periscope alignment target near Q4U7 (see attached picture).

A proposed guideline for conducting future video surveys is attached (via djacks@triumf.ca and genge@triumf.ca).

The seven copper blockers were removed from the Cyclotron tank by the RH group using the service bridge, lift 
trolley, and attached checklist on 2017-01-30.

The monitor box (NE/SW-5/8/10) and series 200, 400, 500, 600, and 700 shields were installed in the Cyclotron 
tank by the RH group using the service bridge, lift trolley, and attached checklist on 2017-01-31 and 2017-02-
01.

The seven port hole covers were installed in the Cyclotron tank by the RH group using the service bridge, tool 
trolley, and vacuum unit on 2017-01-02.

The two ladders were installed in the Cyclotron tank by the RH group using the service bridge, lift trolley, 
and ladder attachment on 2017-01-02.

=================================================================================================================

The monitor box (NE/SW-5/8/10) and series 200, 400, 500, 600, and 700 shields were removed from the Cyclotron 
tank by the RH group using the service bridge, lift trolley, and attached checklist on 2017-03-07 and 2017-03-
08.

The seven port hole covers were removed and the Cyclotron tank seal was cleaned by the RH group using the 
service bridge, tool trolley, and vacuum unit on 2017-03-09.

The two ladders were removed from the Cyclotron tank by the RH group using the service bridge, lift trolley, 
and ladder attachment on 2017-03-09.

The seven copper blockers were installed in the Cyclotron tank by the RH group using the service bridge, lift 
trolley, and attached checklist on 2017-03-09.

Performed continuity test at Cyclotron center post with RH and Operations group members using the service bridge, 
tool trolley, and probe attachment on 2017-03-03.

Lower tank:
Quad #1: All six plates PASSED.
Quad #2: All eight plates PASSED.
Quad #3: All six plates PASSED.
Quad #4: All eight plates PASSED.

Upper tank:
Quad #1: Had some repeat-ability challenges with all six screw-heads/wires. Retest required.
Quad #2: All eight plates PASSED.
Quad #3: All six screw-heads PASSED.
Quad #4: All eight plates FAILED. Retest required.

Performed extra continuity test at Cyclotron center post with RH and Operations on 2017-03-06: achieved a 
successful test on all upper quad #1 and #4 screws/plates. One unconfirmed explanation for the successful retest 
is that the multimeter cable was firmly grounded against the computer monitor rack in the RH service bridge 
control room (see attached picture), which may not have been the case during the initial test.

 The HE2 probe was reinstalled in the cyclotron this morning following the procedure in Document #126165.  An orbital bridge position of 247.35° was used (same as for the removal on Feb 9th).  The installation went smoothly.
