A variable field 180° type beta-ray spectrometer- spectrograph has recently been constructed and placed in operation at Kansas State College. The instrument (Fig. 1) is presently operated as a variable field spectrometer of 15-centimeter radius, with data obtained by Geiger counter detection; or as a “fixed field” spectrograph with data obtained through the exposure of photographic film.
