JRR-3にて生成された熱中性子による即発$$gamma$$線を測定し、試料中の元素位置を1mm以下で分析可能なシステムの構築に成功した。これにより、試料中の元素及び同位体の元素分析が2・3次元的に、かつ非破壊で可能となり、広い自然科学分野及び産業などへの応用が期待できる。本講演ではこの開発内容について発表する。

Since the penetration probability of neutron is higher than that of charged particles, the 2 and 3 dimensional prompt $$gamma$$-ray analysis methods with use of neutron beam is the only way enables the nondestructive, isotopic and position dependent observation on small quantities of samples. We constructed the 2 and 3 dimensional prompt $$gamma$$-ray analysis(2 and 3 DPGA)systems with a high position resolution using focused neutron beam in Prompt $$gamma$$-ray Analysis system(PGA) at JAEA. Using this developed system including the HP Ge-detector, we succeeded in dividing the two neutron captured $$gamma$$-ray peaks from two minute Cd wired-samples, the diameter is 0.25 mm$$phi$$ and the length is 5 mm, sideways arranged at intervals of 1mm.
