Closed 10" gate valve at X1-9 port on X1 beam tube -> PT343A,B now unpumped and no longer measuring beam tube pressure -> Ignore PT343B until further notice -> Replaced 1.5" O-ring valve at X1-9 with portable RGA assembly -> Will leave 10" valve closed for the next several days while I bake the RGA -> Following RGA bake-out, GV14 will be closed and the 10" valve opened for a few days so as to acquire pressure accumulation data on the X1 beam tube module
