When the team going into Hall B attempted to test the rapid access beacon, the interior one would not beacon. We sent an ARM to escort them and the ARM was not able to get the interior beacon to beacon with the test button either, though the exterior one was flashing continuously.

The hall B rapid access beacon is out of frame on the monitor. The camera needs to be tilted so the beacon is visible to the SSO in the control room.

Profiles are acceptable but there is minor concern about the diagonal beam on 2C24 but there isn't anything we can do to correct for skew in their line. They have decided to proceed to the Faraday cup.
