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 |

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 |

Monday, March 23, 2020, 16:13, Isaac Earle, Maintenance, Other, Other, M9 beam blocker MRO completed
|
M9 beam blocker MRO work was completed in the hot cell today. This included replacement of the main shaft seals and replacement of the air cylinders.
Actuation was tested after replacement and the blocker moved smoothly through the full length of travel with approximately 45psi air pressure. It
is ready for transport back to the beamline. |

|
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 |

|
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 |

|
The T1-MK2 target was moved from the hot cell to Hole #5 in the storage pit. The M9 beam blocker was then moved from the beamline to the
hot cell for MRO work. A field of 14.4mSv/hr was measured at 0.5m from the beam blocker during removal. |

|
The following work was completed on both the T1 and T2 target alignment frames
One of the short taper pins on the top of the frame was swapped for a longer version to simplify flask alignment to the frame (now one
pin can be aligned at a time instead of both concurrently)
Three permanently mounted cameras installed to view east/west alignment, north/south |

|
After extensive testing over the last 2 weeks it was determined that the protect monitor
on the T1-MK2 target had an issue with intermittent shorting between the high voltage line and ground (movement of the target ladder was causing the short
to come and go). |
