keyword=Analysis: QTOR current diff -32 --> crash QTOR

Next, the QTOR current went way out of range. We crashed the QTOR using the red button as instructed by Joe.

Seems that MCC thought that our beam positions should be at 0.0 0.0 everywhere instead of at the gold positions. This probably lead to a completely missteered beam that lead to increased temperature on the dump windows with 180 uA, increased temperate diff of the dump window supply and return, and increased ion chamber rates. Called for beam off right away - duration at 180 uA was less than 2 min. See graphs in previous log entry.
