A Model 1024D, Multichannel Analyzer (MCA) built by The Nucleus Inc. and used at the Saskatchewan Research Council SLOWPOKE reactor. This MCA was built primarily for use with scintillation counters and has an output port at the rear that provides stable DC voltage in the 500-1500 volt range. Spectral distributions of gamma rays could be generated and displayed, printed out and/or plotted with these units. MCA units similar to this one began to make an appearance in the 1960s with one of the first ones, a 100 channel one, being developed at Chalk River. By the late 1960s solid state detectors such as the lithium-drifted germanium (Ge(Li) ) detector became available and units with much higher capabilities (4096 channel and more) became common in research laboratories. This unit, manufactured in 1979, was more of a work-horse unit for applied research facilities. The unit was donated complete with the Operation Manual. It stands 46 cm wide, 16.5 cm high and 40.5 cm deep.
