Switched to empty target at 00:30am.
Took empty target data entire shift.
The beam developed some instabilities at the second half of the shift such
that sudden beam current drops were observed, causing HV trips on all four
HV crates. This lasted in a few fills.
Otherwise a smooth shift.
Stopped taking ampty-data at 7:20am, to open the hall for maintenance.
Empty runs: 15189-15195
Started cosmic run: 15196
