missing vacuum interlock permit for reg. HV.

14516 19 17:50 After 2 accesses and consultation w/Dave Pushka at
home it is determined that we cannot fix the vacuum
interlock problem quickly and we will just have to
run without it and watch the vacuum manually until
it can be fixed during the shutdown.
A/C problem was fixed by the maintenance contractor.
Beam returns.

normal by about 2 degrees C. He will be here in
