ITE TM3, entrance module, and 2A3 window flange seals have been leak checked this morning after 2 new seals replacement.The LD base leak rate was 0.0xE-9 atm.cc/sec,  base pressure was 0.0 XE-4 Torr. I sprayed lots helium around the TM3, entrance module and 2A3 flange seals. No any response had been found on LD during the  spraying. All three flanges are sealed perfectly now.

Friedhelm Ames commented to me that there appears to be a short between High Voltage and Ground at TM3 at ITE.

Friedhelm, Anders and I initiated a survey by Andrew from RPG, and entered the Target Hall at approximately 5pm to visually assess the HV cover at the MAA.  There was no clear indication of a problem.  We opted to wait for David to return as we weren't sure exactly what we were looking for.

Friedhelm and Anders confirmed in the Electrical Room that the short is in the Target Hall.

All targets in the vault have been assayed and measured. Results will be posted soon.

All targets in the vault have been assayed and measured. Results will be posted soon.

Results of assay are now attached in a new layout.

All of the serviced F-308's have been moved to the South Hot cell area.

Chad and I leak checked TM1 HS and UC9# VCR fittings. No response had been found on leak detector during the test. I will do helium pressure  test on it at CS later.

TM1 and CS turbo pumps have been started. The vacuum readings are fine on all gauges.

Five targets have been moved from the spent target storage to the mini storage. The targets that were moved are UCx #'s 6,7,8 , SiC #28, and Nb #6.

Five F - 308 flasks containing five ISAC spent targets were moved from the anteroom into the south hot cell area. When the F - 308's were in the south hot cell area the rest of the bolts were installed on all the top covers. All the bolts were torqued and all the cable locks were also installed. All F - 308's  were then moved into the Active Services Area.

Chad and I leak checked the TM3 HS water line with new target installed.  No leak has been found during the check. Leak detector base LR 0.0xE-9 atm.cc/sec, base pressure 0.0xE-4 torr. The line will be helium pressurized at CS later.

TM3 HS water line helium pressure test is done at CS. 70 psi helium , 3 minutes.Base LR 0.0xE-9 atm.cc/sec, base pressure 0.0xE-4 torr.  No response. The line is leak free.

See attached pdf and DocuShare for more photos. It may be possible to clean some of it from the Ground Electrode.

 Chad cleaned the GND electrode yesterday June 26th - see attached PDF. Photos on DocuShare.

I reconnected TM3 in ITE. All turbo pumps have been started. The water supply to TM3 only in ITE. The HV keys are back to electrical room.

5 Shielding blocks have been transferred from ITW to ITE. The ITE is configured to take proton beam.

The TM1 and ITW  were vented with argon gas last night. TM1 had been disconnected in ITW this morning.

Chad and I leak checked TM1 HS waterline with new target installed at SHC. The LD base LR:0.0xE-9atm.cc/sec, base pressure: 0.0xE-4 torr. Chad sprayed helium on both VCR fittings and flushed helium around the target. No response has been found on leak detector. The target HS line is leak tight so far. I will do helium pressure test on this line at CS on next Monday.

I connected TM1 at CS. All turbo pumps have been started. The pumping down is  good so far.

The TM1 HS line is  pressure tested this morning with 70 psi helium  at CS. No response has been found on leak detector.

Stop TM1 and CS turbo pumps and ruff pump. TM1 is disconnect at CS. It will be vented tomorrow morning and moved to ITW.

  TM1 has been connected in ITW . The new roughing pump replaced on last Friday works good. I started all turbo pumps in ITW. The ITW TP1 controller was broken during the starting time. Dimo and I changed a new controller for ITW TP1 in electrical room. The pumping down is good so far. ITW water supplies to TM1 only.
