A direct nuclear activation diagnostic for the measurement of the kinetic energy of deuterium ions in the energy range of 1–3 MeV has been successfully developed. This diagnostic is based on the fact that the ratio of two different thick-target yields which are generated by the same incident ion species can be a sensitive function of incident ion energy. Targets for this diagnostic are made of α-boron nitride (BN) and use the two reactions: 10B(d,n) 11C(β+) and 14N(d,n) 15O(β+). The ratio of thick-target yields depends only on the deuterium ion energy and is independent of ion fluence and detector efficiency. The calibrated diagnostic was then fielded to measure the voltage in a plasma opening switch (POS). Electrical measurements of the POS voltage and the voltage inferred from the BN nuclear activation diagnostic were in good agreement. © 1999 American Institute of Physics.
