    keyword=45deg slanted quartz det results

    45deg slanted quartz det results:
    These are preliminary results from run 4341.

    MPV = 17.8, GSigma=5.3

    This design used two 0.5cm thick quartz plates wrapped with mylar. The quartz was angled at 45deg (parallel to the focal plane). The distance between quartz and pmt is the same as the previously tested configuration (which was not wrapped and not slanted). This configuration does not use a reflector in the light guide beyond the wrapped mylar (this is perhaps makes the biggest difference between this result and the previous result).
