Hi, All Here is an update Mauri gave for CLAS12 LTCC http://clasweb.jlab.org/group_meeting_minutes/Physics/talks_2017/ltcc-8-28.pdf Things are interesting to SoLID LGC and HGC 1. slide 4,5,6 shows nice reflection of thin film as mirror, which could be a cheap alternative to expensive CFRP mirror 2. slide 13, 03-1.1kg/day leak rate.
