Thursday, April 04, 2019, 14:49, Isaac Earle, Safe Module Parking, Development, , , SMP vacuum vessel support roller friction check
|
With the SMP vacuum vessel now installed inside the shield box, a test was performed to measure the torque required to rotate the vessel. At a
moment arm distance of 2.0m a force of 89N was required to rotate the vessel (with no module installed) resulting in a torque of 178Nm. Based on
this, the coefficient of rolling resistance (CRR) was calculated to be 0.007; This is fairly close to available data for similar applications such |

|
The SMP vacuum vessel welds were reinforced to match the specifications on IRH1710 Rev D. In addition a tube stub was added on the side of the
vessel for installation of a PRV. The relief valve installed was Accu-Glass 113150, with 2psi setpoint (not the MDC 420036 model specified on IRH1710
Rev D). The drawing will be updated to reflect this. |

|
The SMP vacuum control system has been wired and setup to be controlled from EPICS. Backing valve control (SMP:BV1) was tested by connecting
to the turbo pump solenoid on TM3 located in the silo directly north of the SMP. The SMP pump (SMP:MP1) was turned on and off through the EPICS interface
and responded as expected. Both convectron gauges (SMP:CG1 and SMP:CG2) responded as expected when the pump was turned on. The readings from |

TM3 was moved into SMP Oct 25 morning. After two nights pumping down, SMP CG1 read 30mtorr this morning. The pump is stopped. SMP will be
vented soon for TM3 moving back to silo. |

Monday, October 28, 2019, 12:00, Isaac Earle, Safe Module Parking, Development, , , SMP shielding attenuation measured & compared to theoretical values
|
The attenuation of the SMP shielding was measured as part of SMP commissioning (Document-170404, R1, Section 4, Test #8)
The field on the shutter side of TM3 was measured without any shielding as it was removed from a storage silo. At 0.5m from the edge of the
module the maximum field was 5.00mSv. After installation into the SMP the maximum field outside the SMP shielding at 0.5m from the edge of the module |

Tuesday, October 22, 2019, 16:26, Isaac Earle, Safe Module Parking, Development, , , SMP shield box grounding
|
A braided grounding strap was attached to the aluminum gear box support on the SMP shield box structure, and grounded by attaching it to the exterior
of an electrical conduit located in the south-west corner of the B2 area at the top of the silo in that corner. The braiding was also connected to
the stainless steel support structure for the SMP vacuum pump. |

Monday, February 11, 2019, 10:26, Isaac Earle, Safe Module Parking, Development, , , SMP shield box and vacuum vessel moved to Target Hall 6x
|
On February 8th the SMP shield box (IRH1675) and the vacuum vessel (IRH1806) were both raised from a horizontal to vertical orientation in
the ISAC-1 Experimental Hall. Hamilton "Mini-Mite" S-MM2-43FS caster wheels were then installed on the base of the shield box and it was
lowered down the hatch to the B2 level. The vacuum vessel was then lowered into the shield box, supported by the rollers, as designed. The |

|
Last week drilling of the additional required holes in the SMP shield box was completed in the Target Hall. This morning the shield box (IRH1675)
was moved to its final installation position in the silo area on the B2 level. The vacuum vessel (IRH1806) was then installed inside the shield box.
The center of the vacuum vessel is 2-3" north of the south travel limit of the crane. Photos as well as measurements of the final position are |

The AC wiring for the SMP motor was inspected by Randy Boehm (TRIUMF electrician) as recommended by Franco Mammarella (TRIUMF electrical engineer).
After inspecting the system Randy required the following changes:
AC wiring inside the control panel be increased to 16awg minimum (14awg preferred)

|
SMP drivetrain design work is currently underway. Alejandro has selected a suitable 1200:1 reducer which will give a vessel rotation speed of 0.21rpm
with a 1725rpm motor (deemed sufficiently close to the SHC rotation speed of 0.17rpm). The reducer however is only rated for 0.33hp, and Allon's
analysis recommended we use a motor of at least 0.4hp |

Wednesday, May 15, 2019, 16:06, Isaac Earle, Safe Module Parking, Development, , , SMP module support flange installed and leak checked
|
The SMP module support flange sub-assembly (IRH1755) was installed today according to drawing IRH1683. Dow Corning 111 sealing compound was used
to keep the o-ring adhered to the lower groove during transportation and installation. The TCS shield plug (IRH1646) was then installed on the SMP
module flange which has vacuum connections for leak checking. Vacuum was pulled on the SMP vessel using the Varian 979 leak detector. After |

Installation of the video lines for the SMP cameras was completed yesterday according to IRH1670 Rev B. All four cameras were confirmed to
be displaying properly in the crane control room. The cameras are powered from an outlet wired to circuit 35/37 on Panel #443 (located in the NHCSA).
This is independent from the power supply for other existing camera systems in the Target Hall. The SMP turntable was rotated through the full range |

|
The SMP assembly was shifted approximately 1.0" north today by pushing it, braced against the south wall, using a 100 Ton capacity air lifting bag
supplied by Beamlines Group. The move was one of the action items identified at the Gate 4A/4B close-out review. During commissioning of the
SMP, TM3 was installed into the vacuum vessel, which required the crane to be all the way at its south limit, so the move is to provide some margin for |
