sPHENIX discussion of the superconducting solenoid

["Than, Yatming (Roberto)" <ythan AT bnl.gov>]

QA would need the welds inspected by the central shop inspector.

There should be a sign-off sheet for the welds with a sketch of the piping section.

Hi Kin,

      I have received the new cryogenic break to replace the original.  We have developed transition ends to adapt to the valve box 10mm tubing.  They have been welded onto the break, all joints have been successfully leak checked, it is now ready to be installed.  I have put in a request to have a temporary welding permit established for the valve box area in 912 scheduled for next week.  We should have a welding machine and a gas bottle necessary for a gas purge during the welding process in place on Monday 9/21.

Regards,

Ray
