By pressurizing the water lines with 70 psi helium David and I detected a major leak on the Coil 1 circuit. The response maxed out on the leak rate on the leak detector and we could also see a pressure increase on the leak detector. ISAC controls reported a change in vacuum at the same time (link).

The Heat Shield and Coil 2 circuit was checked before we moved to Coil 1. No response was detected on these two circuits. We would like to check the remaining circuits as well, but this cannot be done today due to the large amount of helium still present. The remaining circuits will have to be checked tomorrow morning.

All water circuits except Coil 1 were leak checked by David and Anders. No obvious signals were detected except some small possible responses. See attached notes for details.

TM#4 with SiC#29 has been moved to the south hot cell move went well.

TM#4 with SiC#29 post beam electrical check in the south hot cell see PDF for details.

 TM4 was move by myself and Grant. Move went smoothly, no hang ups.

TM#4 with SiC#29 electrical check post beam see pdf for details.

SiC#29 has been moved to the spent target vault. The target was placed in Pail #109 and placed into slot 2B it was 24.7mS/hr upon removal from the south hot cell. See attached PDF of the vault details.

The SiC#29 CTL target has been taken apart with the help of Isaac and Chad. Electrical measurements were done between Target and Heat Shield as the target was disassembled. Work was done on October 2nd, 4th, 7th and 8th.

The megger showed about 30kOhm at 50V with the following changes

• Bolts for CTL block loosened
• Above bolts removed
• CTL block pulled away from Heat Shield
• CTL block removed
• Heat Shield lid removed
• Bolts for target removed
• Shims between target and insulators

The megger showed about 50kOhm at 100V with the following changes

• Target removed. Measured between cathode restraint and HS.

The megger showed OL at 540V with No 3 insulator removed. A measurement on No 3 insulator while it was sitting on the HS showed 70kOhm at 120V confirming that the insulator can no longer hold voltage.

While taking off the coil retainer plate, Chad noticed that all bolts were not tight.

Major portions of the RFQ target have now been sucessfully dismantled. More minor dismantling with conclude this afternoon.

Electrical check of TM#4 SiC#28 (RFQ Target) has been completed. It passed the standard electrical checks for the target part, but the electrical check for the RFQ part is suspect, see the attached PDF for the details.

TM#4 with SiC#28 has been moved from the south hot cell to the east target station move went well.

TM#3 with SiC#28 (RFQ Target) has been moved from the east target station to the south west silo.

TM#4 with SiC#28 has been moved from the south west silo to the south hot cell.

Spent target SiC#28 (RFQ Target) has been moved from the south hot to the storage vault. The target was placed in pail #105 in spot 2C of  the spent target vault. The target had a field of 24.8mSv/hr at about a meter upon removal from the south hot cell. See attached PDF for the status of the vault. It currently only has six free spots left.

SiC#27 has been installed onto TM4. Fit was very good. All electrical connections double checked with mirror.

TM#4 with SiC#27 has had its electrical check. See attached PDF for details.

Electrical check of TM#4 with SiC#27 under vacuum at that conditioning station. See attached PDF for details.

Module has been moved from conditioning station to the east target station. Move went well.

TM#4 with SiC#27 moved from the east station to the south hot cell. Fields at East MAA were 127mSv/hr and the fields at the south hot cell was 77.5 mSv/hr.

SiC#27 has been moved from the south hot cell to the spent target vault. Target was placed in pail #96, placed in slot 3A, the fields at the hot cell were 178mSv/hr. For the latest on the vault see attached document.
