The SNS Front End 2.5 MeV Emittance Device was first tested with beam from the RFQ on February 1, 2002. The hardware is simple in concept, but has some non-obvious behavior that needs to be understood before the output data can be used to construct renderings of phase space intensities, and compute emittances. This note documents the wiring, channel mapping, offset subtraction, channel sensitivity calibration, and probable slit scattering.
