keyword=Balloon 'excursion' and MWDC trip info
The balloon in the magnet overfilled and pressed against the front gas
window hard enough to push a bunch of gas through the inflow
over-pressure bubbler. It also disturbed the chamber enough to trip the
several HV channels.
The balloon was deflated to a reasonable level and I increased the gas
flow to the front chamber to refill what had been lost. After a few
minutes the chamber started to bubble at the outflow bubbler again. I
backed the chamber flow off to the normal value and asked for the HVs to
be restored.
So far, so good.
