* 10uA on deuterium in last SBS kinematics (highest currents/occupancies so far): [https://logbooks.jlab.org/entry/3931870 https://logbooks.jlab.org/entry/3931870]

* Currents and set voltages in the EPICS archiver as of Monday [https://logbooks.jlab.org/entry/3932174 https://logbooks.jlab.org/entry/3932174]. This was always reported as a snapshot in the HALOG with the BB EPICS start of run entries.
