Last 24 hours we took very little production data due to the accelerator down. The target polarization was around 80% according to the NMR. Most of the day went into dealing with the problematic cavity in the accelerator. We finally got beam at around 2am. We performed the standard beam restoration procedure and started taking data sometime around 5am. Unfortunately the beam was unstable with very frequent trips. Also there are some relatively long beam down times . We also had an issue with RICH which was dealt with by Gagik and Valery.

We took roughly 55M triggers on NH3 target and HWP IN. After the switching the target. PROD66_PIN just after the target switch is 17067. 

The plan is to take production data until Monday morning in the same configuration, and then switch HWP to OUT in the morning.
