keyword=Beam Current spikes seen
Kathy notices that there have been two "spikes" in the
beam current sent to us, of well above our requested 4 µA. See the
below strip chart, where the greenish line at the bottom is the Hall A
current in µA. While I type this, there has been a third. Each time
it is right after a beam trip, i.e. at the end of the ramp back up.
Kathy call's MCC to inform them of this, and express our concern.
This is especially dangerous, since if we were running at higher currents a spike
of this magnitude could very likely rupture the 3He target cell.
