keyword=Large Charge Asymmetry
During the entire run so far, we have had an extraordinarily large charge
asymmetry.
To prepare for a large charge asymmetry run, I ask Mark Dalton to show me
how to add a large asymmetry into our beam. When he opened the IA GUI,
he saw that we had been running with a very large charge asymmetry (Mark
estimates -5.5%) since Dec. 7 at about 08:30.
It appears as if someone may have reset the IA values. There are four
parameters that run from 0 to about 64000. All of the values were close
to zero (but not identical).
Both Hall C and Hall B have been informed.
