After noting that a lower fan speed gave a more uniform distribution of events, we decided to lower the fan speed for loop 3 H2 target to 42 Hz for the remainder of the run (https://logbooks.jlab.org/entry/4295482). We finished positron running and while changing the magnet settings to go back to production running at KinC_x36_4, Dave Meekins made a quick access to increase the pressure in loop 3 (https://logbooks.jlab.org/entry/4295752). A comparison of the Y_tar distributions at 25 psia and 30 psia can be found here (https://logbooks.jlab.org/entry/4296639, https://logbooks.jlab.org/entry/4296687). Beam was temporarily stopped at ~2:00 am during Saturday Owl when the chiller turned itself off. Thanks to an alert Hao Huang for fixing this problem and bringing us back into production mode (https://logbooks.jlab.org/entry/4295992, https://logbooks.jlab.org/entry/4295999). Plan is to finish production running at KinC_x36_4 and then follow this (https://logbooks.jlab.org/entry/!
 4296499). Let's have an RC meeting at 11:00 am today in the CH conference room to discuss more.
