Development of a Data Acquisition System for a Multiple Gamma-Ray Detection Method

摘要

To measure neutron cross-section data of the minor actinides, we construct a 4-Ge-spectrometer utilizing a multiple gamma-ray detection method. This spectrometer consists of 30 Ge crystals and BGO anti-Compton shields. Generally, a data acquisition system for such a large Ge spectrometer consists of many NIM modules; it requires a large space and huge cost. To overcome these problems, we developed a new data acquisition system with digital signal processing techniques. This system is mounted in a 19-in. VME sub-rack, and the cost of this system is less than 2000 US dollars per one Ge detector channel.
