Use of List-Mode Data Acquisition Systems for Performing Benchmark Subcritical Neutron Measurements

摘要

With the combined advances in computer processor miniaturization, data recording speeds, data processing speeds, and data storage capacity, new designs for data acquisition systems are being developed for the next generation measurement systems. Data acquisition systems made up of racks of older NIM and CAMAC electronics can be replaced by data acquisition systems with smaller form factors and increased information recording capabilities.rnOne of the most versatile designs for a data acquisition system is a list-mode data acquisition system [1]. For list-mode data acquisition, detection events can be time marked, channel marked, module marked, etc. and recorded as one large list of data. For an active measurement, the time marking of the pulse from an active source can be incorporated as part of the data list. This list of data can then be processed and analyzed using the appropriate analysis technique. Multiple analysis techniques can be used to process the same data list to infer different parameters of interest from the measurement.
