The active collimator is a beam position monitor that consists of a set of machined tungsten wedges placed in two concentric rings about a central hole of 5mm. When the beam hits a wedge it creates a current which can be readout through a preamplifier. Each ring consists of 4 wedges corresponding to +X, +Y, -X, and -Y directions.
