A Pneumatic Transfer System for Neutron Activation Analysis

Abstract

For instrumental neutron activation analysis (INAA) using short-lived nuclides with a TRIGA-II research reactor (100 kW), we renewed a pneumatic capsule transfer system. The new system consists of two sets of capsule loading and ejection ports and one irradiation point, thermal nentron flux of which is 1.5×10¹²n⋅ cm^-2⋅ s^-1. Selection of a capsule from the two ports and its starting and ending time of irradiation etc, are controlled with a personal computer (NEC PC-9801 m2), which displays all the information that is required for gamma-ray spectrometry with the GAMA system.
