Development of an automatic prompt $$gamma$$-ray activation analysis system

自動即発$$gamma$$線分析装置の開発

大澤 崇人

JRR-3ガイドホールに設置された即発$$gamma$$線分析装置に6軸多関節ロボットを導入し、これを制御することで自動分析・制御システムを開発した。AutoPGAと名付けられた制御プログラムはLabVIEW2011で開発され、自動分析と自動制御がシステムで統合されている。最大14試料を自動で分析可能であり、従来の手動交換と比較して圧倒的な分析効率を達成するだけでなく、自動制御によってバックグラウンドの低下にも効力を発揮できる。

An automatic prompt $$gamma$$-ray activation analysis system was developed and installed at the Japan Research Reactor No.3 Modified (JRR-3M). This system is mainly composed of two personal computers, four programs, a six-axis vertical revolute joint robot, and a data acquisition device. The main control software, referred to as AutoPGA, was developed using LabVIEW 2011 and the hand-made program can control all functions of the analytical system. The core of the new system is an automatic sample exchanger and measurement system with several additional automatic control functions integrated into the system. Up to fourteen samples can be automatically measured by the system. Therefore, this system can not only dramatically increase the efficiency of routine measurements but also decrease the background level of $$gamma$$-rays for the analysis through the use of a sophisticated automatic control system.
