 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 of motion (reached CW and CCW limits) and the cable routing and reel take-up system performed as expected.

ITW secondary vacuum was bad in last two days after TM4 was connected in ITW. Today when check the exit 2 module, I found a small needle valve on exit 2 module top was slightly opened for some reason in past months. The valve is closed . ITW vacuum is returned to normal status.

  1990   Monday, September 30, 2019, 11:27 Isaac EarleSafe Module ParkingDevelopment  SMP vacuum vessel modifications completed

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.

Welding was performed in the TRIUMF machine shop.  A larger capacity forklift was rented to move the vessel back and forth between the shop and the Meson Hall loading bay where the main crane was used to flip the vessel between welds.

After welding the vessel was leak checked using a blank-off plate (helium leak tight).  The vessel was then returned to the Target Hall, the top flange IRH1755 was re-installed, and the TCS shield plug was installed on the flange.  The vessel was pumped down over the weekend using the SMP vacuum pump, and reached 8mTorr by Monday morning.  A helium leak check was performed in the Target Hall:  baseline leak rate 0.0E-9 atm-cc/sec, 0.0E-4Torr port pressure, no response to generous helium spray on PRV and around both seal locations for the top flange.

Remaining re-assembly of the SMP will now proceed.

TM4 HS Leak check result is good . No leak. electrical check after target installation: Bias to chassis 550 Mohm. Coils are shorted each other and shorted to 60 KV bias. ABCD to 60KV bias 500V Megga measurement are 100M at least which is good. EE to bias are OL at 500V. The electrical check result is good.

  2006   Thursday, October 10, 2019, 16:17 Adam NewsomeSafe Module ParkingDevelopment  SMP Main Panel: Relay Addition for E-Stop Circut

An update was made for the E-stop and power supply system in the SMP main panel. Upon testing remote control, it was determined that the Opto 22 AC module was not sufficiently rated to handle the current draw of the motor (5A fuse versus motor 5.7A current draw). The design was modified so that the E-stop chain, which supplies 120 VAC line voltage through the main panel E-stop then the remote module (or local pendant when plugged in), will now activate a relay rather than run directly to the motor and 24 VDC PSU. This means that this E-stop chain will not carry the current draw of the entire system. Rather, the relay that is toggled when the E-stop circuit is closed will supply the system with power - this relay is rated for 15 A so the main 10 A fuse will blow before the relay fails in the event of a current spike. The new relay was installed on Oct 9, 2019. The local pendant was tested at this time and worked as expected (motion control, E-stops). On Oct 10, 2019, remote control was tested again and is working as expected (motion control, E-stops). In the attached schematic screenshot, the modification is CR7. In the image of the panel, this relay is located in the top left.

 

Edit: TRIUMF electrician Joel Semilla has seen the design change and verified it is acceptable.

  2007   Tuesday, October 15, 2019, 16:42 Isaac EarleSafe Module ParkingDevelopment  SMP flange alignment tested using shield plug

 As a preliminary test in preparation for SMP commissioning, one of the steel module shield plugs was installed into the SMP to check the positional and rotational alignment procedures.  The following is a summary of the steps performed:

  1. Shield plug lifted with crane and rotated to an arbitrary (non-orthogonal) position
  2. Using the crane pendant the shield plug was roughly aligned over the SMP and lowered until the base was within 15cm of the top of the flange
  3. The SMP flange was rotated to roughly match the orientation of the shield plug 
  4. Precise positioning of module achieved visually from within the Target Hall using crane for NESW position and SMP for rotation
  5. Module lowered into SMP vessel (not resting on base of vessel)
  6. Target Hall crane was then set to "Test Mode" and operated from the crane control room
  7. Crane position with the module centered in the SMP vessel was recorded as E-W: 18.5495m,  N-S: 4.9065m
  8. The shield plug was lifted from the SMP, moved to an arbitrary location in the Target Hall, and set to a different arbitrary rotational position
  9. The SMP flange was returned to the "centered" position
  10. The shield plug was moved to the previously recorded location over the SMP and lowered to within 15cm of the top of the flange (using cameras)
  11. Steps 3-5 were repeated using only camera views to achieve alignment (SMP rotation was controlled using the pendant with instructions by phone from the crane room operator because the module for remote control currently requires a part to be changed)

Official commissioning of the SMP will now be planned as per the commissioning plan Document-170404

  2010   Tuesday, October 22, 2019, 16:26 Isaac EarleSafe Module ParkingDevelopment  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.
