keyword=Current Status: Work Done, Harp looks like working, Beam Permit, etc.
What we did during this control access:
1, BCM switched to 1MHz recevier. Alex is checking the output.
2, Our techs were so nice to find a way to replace a part on the ear of
the target holder. Hopefully it can reduce the effect of blocking
electrons by the ear. (Thank our techs for doing that for us.)
3, Harp. The good new is that Tony found the problems of the SuperHarp,
and he fixed the step motor. He saw noise signal without beam so
hopefully we are able to see the electron signal when beam back. If Harp
is working, we are going to run the BPM and slow raster calibration asap.
Alex is working on it.
