An experiment in which an optical trigger device for the detection of muons from B-meson decays was tested using a muon telescope at Fermilab Experiment E789. A data set of 140,000 muon events was examined, recorded from January 8 through January 15, 1992 in three separate data-collection runs. The data was filtered and fit, using a least-squares analysis, to correspond to linear trajectories through a piece of MgF2 crystal. An analysis was done on the data to relate muon incident angle on the crystal to detected intensity of internally reflected Cherenkov radiation and to examine the sharpness of the resulting curve. A curve resulted which showed a much more gradual increase then was expected. Computer modelling indicated that the observed curve was the result of dispersion as various wavelengths of Cherenkov radiation became internally reflected at different incident angles coupled with the variable spectral response of the photomultiplier tube.
