An avalanche photodiode capable of detecting the fast component of the scintillation light of barium fluoride is being developed by a Caltech/JPL/RMD collaboration. The device has high quantum efficiency at 220nm, the wavelength of the fast scintillation component (0.9ns) and excellent discrimination against the 300nm slow scintillation component (650ns) of barium fluoride, as well as good rise and decay times. This device is intended for the calorimeter of the Mu2e experiment at Fermilab.
