Nakamura, M; Simonof, G S

A multiparameter pulse-height recording system was built and has been in operation for approximately one year. The system was used principally in studies of nuclear fission. The system can record up to ten coincident parameters for each nuclear event. Stretchers are used to store the pulse amplitudes temporarily, and then serially read the stretchers into an ADC unit. The digitized pulse heights are stored in predetermined locations of a magnetic-core buffer store. The buffer store can handle 512 pulse heights before dumping periodically onto magnetic tape. Each parameter has 258 channels of resolution. The magnetic tape format is IBM compatible,'' with a recording density of 200 characters per inch. It takes 80 msec to dump the buffer store information onto magnetic tape. This 80-msec interval limits the speed at which information can be recorded. The information on the tape can be read back into the magnetic-core store by selecting one of the parameters and obtaining a singles'' spectrum of that parameter. When it is thought that reasonable data are collected, the reel of magnetic tape is taken to an IBM 7090 computer for delayed analysis. (auth)
