keyword=Compton chicane problem
It seems that the problem is due to the fact that the Fast FeedBack is off. So it may be some beam halo scrapping somewhere and that are flooding our detectors. It should be safe to run through the chicane since the FSD should have tripped the beam if something bad had happened.
So after a discussion with the program deputy and the run coordinator we have decided to keep running through the chicane. However we will not trying to tune the chicane since it would have required the hall B authorization and since the problem should disappear when the Fast FeedBack will be repaired (expert coming back today).
For safety I have disabled the photon detector. We are not anymore able to take polarimetry measurement. But when FFB is on, I'll try to take data.
