Completed work at m9 beam line:
- Removed existing service stand and associated cable and water services. Legacy b1 water services still need to be removed for future magnet installation.
Old service stand is currently in warm cell waiting for disposal. |
Friday, February 28, 2020, 09:06, Isaac Earle, Development, Other, M9, M9 Q1Q2 service stand floor plate installed 
|
The M9 service stand floor plate (TB23351) was installed in the M9 pit yesterday. Prior to installation all 5 threaded inserts were tested
using a 1/2"-13 stud tool on an RH pole. The west most hole (shown in red below) had damaged threads and the stud could only be threaded in
2 turns. All other locations (shown in green) had usable threads with 6-8 full turns possible with the stud tool. The plate was installed using |

Wednesday, March 11, 2020, 10:29, Isaac Earle, Development, Other, M9, M9 Q1Q2 service stand foot plate installed
|
The M9 Q1Q2 "foot" plate (TB23363) has been installed over the floor plate. A nominal gap between the plates of 1/2" was set
before lowering the plate, it was then leveled using the three adjustment bolts resulting in a larger gap. After leveling, the plate was lifted to
remove the spirit levels and lock the position of the leveling bolts. The plate was then re-lowered and the tiedown bolt assemblies (TB23383) were |

Monday, April 06, 2020, 15:02, Isaac Earle, Standard Operation, Target 2, M9, M9 beam blocker returned to beamline
|
The M9 beam blocker was returned to the beamline today using the RH shielded transport flask. The top flange o-ring was replaced before installation.
After installation the "Lift T" assembly was removed, and electrical cable and air supply connected. Correct functionality of the
limit switches was confirmed with the control room. Actuation of the beam blocker could not be tested at this time because control takes place through |

Tuesday, June 09, 2020, 17:01, Isaac Earle, Development, Other, M9, Cables and helium leak check line installed to M9 service stand
|
The 10-pin thermal switch wire, 2-pin steering wire for Q2, and a 1/4" copper tube for remote helium leak check were installed through the
service chase with the power cables and connected to the M9 service stand. Approximately 10m of extra cable (2-pin and 10-pin) was coiled and left
in the cooler section of the service chase after the first sharp bend. The cables and the tubing are currently run as far as the vertical cable tray |

Wednesday, June 10, 2020, 08:58, Isaac Earle, Development, Other, M9, T2-M9 and M9-B1 flange scan data
|
Laser tracker scan data from 2017 and 2019 attached as a backup. Original files from Beamlines Group who also keep copies on \\trwindata\experimental
support\alignment\T2-M9_data |

Friday, June 12, 2020, 13:54, Isaac Earle, Development, Other, M9, M9 Q1Q2 water header installed
|
The Q1Q2 water header (TB23481) was mounted this morning as per installation drawing TB23400.
Heat shrink tubing was applied to the B1 power cables (two positive, two negative) over the length of cable in the highest field which was showing
some signs of radiation damage on the insulation. The tubing used was McMaster-Carr PN 75665K932 (Clear PTFE, 4:1 shrink ratio, 1.0" ID before |

Tuesday, July 07, 2020, 13:22, Isaac Earle, Development, Other, M9, M9 Q1Q2
|
The M9 Q1Q2 magnet assembly lift beam has been installed according to drawing TB23401. The side-to-side as well as beam-axis direction adjustment
features were tuned so that the assembly is level when lifted.

The diagram below shows the wiring for the two connectors on the service stand (the wires running from the stand to the power supplies. (see TB23400
for details)

Thursday, July 09, 2020, 06:44, Isaac Earle, Development, Other, M9, Alignment of M9 Q1Q2 magnets complete
|
Mike Vogel reported that alignment of the Q1Q2 assembly w.r.t. the T2 and B1 flanges was completed on July 7. This was performed in the test
stand with the flange positions set to the measurements taken in the 2019 shutdown. Alignment to the theoretical location was achieved within 0.1mm.
The axis of the Q1 and Q2 magnets were aligned to each other previously within similar accuracy. |

Wednesday, May 04, 2022, 11:27, Adam Newsome, Standard Operation, Target 2, M9, M9 and M20 Beam Blocker Actuation Test
|
The beam blockers for M9 and M20 were actuated, and vacuum was monitored to ensure no disruptions. Both actuation tests were successful. Motion was observed
and no abnormalities noted. Cabling and air connections checked: OK.

|
Some oil was noticed around the hot cell window, on the control panel, and on the ground below the control panel. A leak is suspected.
Suggest tightening all bolts to specified torque along the window, and monitoring overflow oil level (position today was marked). If the problem |

Thursday, February 01, 2024, 11:14, Albert Kong, Standard Operation, Target 1, Hot Cell, T1-MK1 Flush and Purge on Hot Cell
|
The recently removed T1-MK1 target ladder was flushed with city water for ~30s at all target positions. It was then purged with compressed air at ~5
psi for ~1 minute at all target positions. We then left the target ladder in pos5 to fully extend the bellows and allow it to dry overnight.
This ELOG will be updated as we progress with work done to dry the target ladder and eventually exchange the spent targets. |
