Yesterday, we could fix a lot of problems in the hall during the RF recovery. We were getting stable beam back around 22:00 and checked C-hole. There were some indications of a hot spot in a corner of the x-y positions which is why we took some runs with larger raster. However, it was found that this "hot spot" is only due to the interference of the raster frequencies at the edges of the raster size (see Zhihong's halog entry https://logbooks.jlab.org/entry/3606945). We continued production data afterwards

Another issue during the night was repeated target alarms from the heater power and temperature sensors spiking to unreasonable values (https://logbooks.jlab.org/entry/3606945). It seems like a glitch / problem with the temperature sensors which are flatlining for some seconds and the heater power is reacting on it (https://logbooks.jlab.org/entry/3607083). After 1-2minutes everything went back to normal. This happened with beam on and off.

There are no special activities planned in the next days so we are continuing taken production data and I can hand over the phone to Eric our next RC.
