keyword=MCC gives up on beam tuning for tonight
At 04:00 MCC informed us that they had given up on beam tuning for tonight. They could not get rid of a "stripe" seen on the viewers.
The beem spot seems to be extended vertically. They could not
send a CW beam above 0.5uA without tripping some ion chambers.
Another problem they noticed was a strong dependence of Hall A
beam energy on Hall C beam current.
While they played with the beam we noticed a strange effect on
the upstrem BCM - the voltage readout was sometimes zero.
