RF-Cavity Monitor

This is a tuned RF cavity and the beam current is measured by measuring the power of the RF radiation coupled in the cavity. These provide very good relative measurements of current. There are three of these devices in the Hall C beamline. BCM1 and BCM2 are at the location of the Unser monitor and BCM3 is located on the last beamline girder immediately preceding the target. (BCM3 is known as the ``Hall C" cavity by the MCC.)
