We changed to negative polarity runs during day shift yesterday and started with 7 uA beam current. We scanned a couple of beam current settings for ~20 mins (7, 10, 15, 30, 25 uA) and settled on 11 uA for the day shift. Eventually after looking at the tracking efficiencies, we settled at 12 uA for the rest of the swing and owl shifts (https://logbooks.jlab.org/entry/4033932). The plan is to continue data taking at this configuration for another ~2.5 days. For the small angle configuration change that happens sometime during the weekend, Steve Lassiter is happy to monitor this configuration change remotely so we DO NOT need an access.
Let's have a brief RC meeting today at 11:00 AM EST.
