LSI-11 based pulse height analyzer. [For processing gamma spectra from neutron activated rabbit samples]
A remote-local controlled 4K channel, 32 bits per channel pulse height analyzer (PHA) built around a Fortran programmed LSI-11 is described. The PHA is made up of an LSI-11 microcomputer with 20K of memory, an interface to a Northern Scientific ADC, an 8 bit parallel link to a master LSI-11 computer, and a serial 9600 baud link to a shared DEC VT55 graphics terminal. There are 4 PHAs all networked to a remote master computer that make up the total PHA system. This PHA system will gather X-ray and ..gamma..-ray spectra data from neutron activated rabbit samples for the Lawrence Livermore Laboratory NURE project. NURE is an acronym standing for the National Uranium Resource Evaluation. The goal of NURE is to conduct a multidisciplinary survey of the uranium mineral resources in the United States and publish an assessment of the national uranium reserves by mid-1981. The purpose of LLL's part is to process the samples taken from the western 1/4 of the U.S. and publish the results. A secondary purpose of the analysis is to identify any other elements in the sample for future reference.
