Abstract

A new method, combining activation by neutrons and charged particles with ultra low-level gamma-ray spectrometry, aimed at obtaining a better understanding and more adequate measurements of MeV particle leaks in magnetic fusion devices was studied here. A total of 36 samples containing Ti, LiF, B₄C and W were placed in a boron-nitride holder mounted on the ceiling of the JET Tokamak. The samples were activated by 63 pulses from a D-³He plasma and were later measured using underground gamma-ray spectrometry. The radionuclides ⁷Be, ⁴⁶Sc, ⁵⁴Mn, ⁵⁶Co, ⁵⁷Co, ⁵⁸Co, ¹²⁴Sb, ¹⁸¹Hf, ¹⁸²Ta, ¹⁸¹W and ¹⁸⁵W were detected in several of the samples, with very low levels of activity of ⁴⁷Sc and ⁴⁸V found in a few of the samples. The various production channels for the radionuclides in question are discussed.
