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.

 The spent target in the south hot cell has been moved to the spent target vault. It was placed in spot 1B of the vault in pail number 218. See attached for vault details.

 Results of the electrical check of TM4 without target and with UC27 and 28

Tm2 with Ta 59 has eben connected in ITE. Turbo pumps are started. See checklist

TM2 has been moved from the Conditioning Station to ITE with Ta#59 target.

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.

TM2 has been connected at TCS this morning. helium pressure test on Tm2 HS line is done. No leak.

 TM#4 with UC#28 has been moved from the south hot cell to the west target station.

 The spent ZrC#8 was moved from the south hot cell to the spent target vault. It was placed in pail 217 and the pail was placed in slot 3A of the vault, it was 205mSv/hr when removed from the hot cell. Also the pail was filled with junk stuff that included 

wire, a wire scanner, IMG guage, target bolts and a water block bolts. Also there are only two spots left in the vault.

Heat shield has been removed from ZrC#8.

Tuesday, October 01, 2019, 15:15: Started roughing.

Tuesday, October 01, 2019, 16:30: Started TPs

Tuesday, October 01, 2019, 16:34: All TPs at speed

Conditioning completed over the weekend by RIB operations. The shutter was left closed on the module, so no beam could be seen on the FC. Conditioning otherwise OK.

 The results of the electrical check on TM#2 with the Ta#59 target and without before the target was mounted on the module.

ZrC#8 has been removed from TM2. Upon removal of the high current tube heater bolts it was noticed that the tube was broken. Also the 9 pin connector has an arc mark (see pictures attached).

Ta#59 has been installed with new fasteners. High current fasteners torqued to 130 in lbs.

1 Jumpers between 60KV common and FEBIAD lines were connected in an unusual way.  This should of had no impact on the ZrC run but would have to be corrected for any future FEBIAD runs.

2 Feedthrough U was mislabeled (label has been removed)

 TM#2 with ZrC#8 has been moved from the east station to the south hot cell.

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.

 All targets in the mini vault have been repackaged and are now ready to be loaded into F-308s. All the target pails have new numbers see attached sheet for details.

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

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