Subject: 1AQ15 insulator repair 

Assisted beamlines in replacing 2 insulators on 1A Q15 magnet. #10 and #14 insulators were found to be leaking at the ceramic, where the stainless steel fitting joins the insulator. They were both replaced. During re-installation of the #10 ceramic, the VCR coil termination broke off the coil end and a new one with updated design (see TBP0379) had to be soldered back in its place. The original SS fittings are deemed to have problems in their construction and have been replaced over the years.

Video capture shows soldered fitting with a large glob of excess solder on bottom. Other photos show new fitting soldered in place and completed assembly of fitting with new insulator.
