A Slatis-Siegbahn type beta ray spectrometer was modified by installation of a scintillation detector, and by the addition of a mechanism for automatically scanning and recording a beta spectrum at any desired rate. An analysis of pulse heights indicated that about 80% of incident 25 Kev. electrons could be detected with a background of 150 counts per minute. A study of activities arising from proton bombardments of rheniun and tungsten was made using the beta ray spectrometer in conjunction with a sodium iodide gamma spectrometer. [...]
