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)

 Results of the electrical check on TM#2 with ZrC#8 post beam.

 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.

Ramping up HV to ~30kV, encountered problems and had to drop back to 28kV. No response on IG1 or anything else during sparks. Lots of charging-type behaviour on the bias current. Protons at 55uA

Tuesday, September 17, 2019, 02:02 : 15 mins with only 1 spark at 30kV so increased the bias

Tuesday, September 17, 2019, 02:31 : 32kV. Current unstable

Tuesday, September 17, 2019, 02:41 : Current continues extremely unstable but not much sparking....

Tuesday, September 17, 2019, 02:53 : Proton beam trip initially settled the bias current down, but then current began climbing pretty steeply with protons still off

Tuesday, September 17, 2019, 03:28 : Protons dropped to 40uA from 55uA, Bias current is much more stable and no sparks for 25mins

Tuesday, September 17, 2019, 03:36 : Raising voltage easy to about 33.5kV then instability and sparking similar to around 31kV at 55uA p+

Tuesday, September 17, 2019, 04:45 : Lowered protons to 25uA and no sparks though the current is not stable

More things but forgot to write them down. Spreadsheet attached.

TM4 was connected in ITW this Tuesday. See attachment for checklist.

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.

ITW water interlock check is finished. Everything is good.

TM4 has been moved from the Conditioning Station to ITW with UC#27 target.
