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.

TM#4 with SiC#26 HP has been checked electrically it has passed. It was noted that the Megger check of the Oven to Chassis (earth ground) and Oven to 60kV Common is low but will not hinder running, according to Don Jackson.  Also yesterday the transition piece that sits on the 55 pin connector was damaged from excessive handling, it was removed and repaired and it now back in place.

TM#4 with SiC#26 HP has been moved from the south hot cell to the conditioning station.

TM#4 moved from conditioning station to south hot cell. For further leak checking.

TM#4 with SiC#26 HP moved from the south hot cell to the conditioning station.

 The silicon carbide targets voltage was raised to 42 kV today before continuous current draw was observed. It took roughly 10 minutes to raise the module to this voltage with only the occasional spark. The ION gauge reading was 2.0 x 10^-6 T, The service cap IMG 3.6 x 10^-6 T, and the secondary vacuum was 4.5 x 10^-6 T. Setup check and conditioning was performed by Pierre.

TM#4 with SiC#26 HP move from the conditioning station to the East Target Station, move went well.

HP febiad target SiC#26 was installed onto Tm4 on Monday morning.

"JP's" connector required lossing of the two mounting fasteners. Connector was pushed tight to its mating half on the source tray and both fasteners retightened, and the mating checked; it was good.

Two new 7/8 long 3/8-16 fasteners were used for the febiad coil connections.

Installation went well.

Leak check was performed:

Base Pressure: 0.0x10-4

Stable leak rate 0.0x10-9

Left vcr joint was checked two times with a 2 second spray of helium with a 60 second waiting time between sprays; no response.

Right vcr joint was checked two times with a 2 second spray of helium with a 60 second waiting time between sprays; no response.

Fllod of system with a 6 second spray; no response.

TM#4 with SiC #26 was moved from the East Station to the South Hot Cell. Bevan was at the helm of the PLC. There was no issue with the move.
