Log Number: 4535045Logbook(s): Body: 

During Beam Studies on 8/5/2026 SSG would like to perform BELS HCO tests.
Tests will require establishing high power beam to Hall C and should last around 1 hour allowing beam delivery through most of the time.
Tests will verify BELS ability to shut down the beam using three levels of controls:
EPICS Envelope - tests will take around 10 minutes. Requires temporary change of the EPICS Power Limit. Trip will occur by switching to Beam Sync mode.
Operations Envelope - tests will take around 20 minutes. Requires temporary change of the OPS Power Limits in BELS PLCs.
