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:

1. AC wiring inside the control panel be increased to 16awg minimum (14awg preferred)
2. Wiring between the control panel and motor control box be increased to 14awg
3. Power cable to the motor be increased to 14awg
4. Current rating for MS connectors be checked and replaced if below 10A
5. Prefer that motor control box components be relocated to the control panel to reduce number of AC wires and connections (preferred but not mandatory)
6. A dedicated ground wire is required in the cable going to the motor (if not already in place)

After these changes have been made the inspection will be repeated.

July 31, 2019 update:

Items 1, 2, 3, and 6 from above were completed.  14awg wiring was used for wiring inside the control panel (Item 1).  Current rating for the MS connectors was checked and is over 10A (Item 4).  Motor control box components were not relocated to the control panel at this time (Item 5).

Randy repeated his inspection today, and approved of the updated 120V wiring.

Adam updated the SMP electrical and control schematics (IRH1868-1874)

New source tray was installed on TM4 yesterday. LD was used to pump down all water lines. Tube heater +D circuit has a big leak  around water block area. At base LR5.5 XE-5 atm.cc/sec, base pressure 170 mtorr, When Chad  moved this helium probe close to  water block area, The leak rate on LD went to maximum level right away. When the probe was moved out of water block area, the LR went back to base level. The test repeated again with same result. Also, Before helium spray test, I applied 80 psi air into the circuit. The air pressure can not be held in the circuit. The pressure drop on the line is quick. This shows a big leak on  D line as well. The rest water lines are fine. I pumped all of them down to LD bottom scale without problem. Chad and I helium sprayed window and MSP water blocks. No leak has been found.  The only line we have problem is the D line.

D line is still leak after repair and installation. We suspected the c-seals issue on this module. So, all water lines have been sprayed with helium for leak check.  Found "B" line target oven negative  is also leak. The rest line are good on helium spray leak check.  The further investigate on thi issue is taken place now.

 July 3:

Yesterday, TM4 B line was supplied with water at TCS for testing.  TCS: IG1 and IG2 had big response on it. See attachment. The water was disconnected right away, and line was purged. Vacuum recovered after overnight pump.

Tm4 has been moved from SHc to TCS without containment box. It is a new source tray on TM4.  A layer of plastic sheet was put on TH floor on module pass route during the move.

Electrical check on TM4 with spare test target. PQ is still shorted to RU. But, The short between 60KV bias and PQRU which we found last time is gone.  Target to PQRU at 250V mega measurement: 22.08 M. All conductivity between ABCD are about 5.0 m ohm which are good. All other ohm meter and Mega measurements are OL. Helium spray leak check on HS target VCR fittings is passed. Two blank offs are installed on source tray window cool lines. They passed  leak checked at SHC as well. 

 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 the two gauges were consistent throughout the mili-Torr range.

The work was done by Ray Mendoza under WP I2019-07-24-4 (work request #5239).

TM2 has been disconnected in ITE. The bias jumper between U and T was burned out during the last beam time.

LD base leak rate, 0.0Xe-9atm.cc/sec. Helium pressure, 70psi. 5 minutes each circuit. No response on all water line except containment box window which has a VCR leak issue now. Window line leak rate, 2.3Xe-4 atm.cc/sec.

TM4 is moved from TCS to SW silo this morning. The move is good.

 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.

The wiring for the SMP remote control module was inspected by Joel Semilla (TRIUMF electrician). The module was plugged in to verify there were no issues. No changes were suggested, and then wiring was approved.

TM3 has been moved from the Middle-East silo to the South Hot Cell.

TM3 has been moved from the South Hot-Cell to the Middle-East silo.

TM4 has been moved from the Conditioning Station to the South Hot-Cell.

The TM3 containment box has been installed onto TM4. No issues, leak checked ok.

ITW water interlock check is finished. Everything is good.

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.

 Three of the five targets in the mini storage have been repackaged into the stronger pail.

 Another target in the mini storage has been repackaged into the new pails. With one remaining to do which will be done on Monday.
