In the light-ion-beam fusion program at Sandia, an intense Li beam is being developed to drive inertial confinement fusion targets. Since beam purity is an important issue, direct nuclear activation diagnostics based on thick target yields of the reactions {sup 7}Li(p, n){sup 7}Be, {sup 10}B(p,{alpha}){sup 7}Be, {sup 19}F({sup 7}Li, d){sup 24}Na, and {sup 11}B({sup 19}F,2p){sup 28}Mg have been developed to measure the proton, Li, and F content of the beam. Target materials used were LiF and BN. To calibrate these diagnostics, a Van de Graaff accelerator was used to measure the thick target yields as a function of ion energy for each of the ion and target material combinations. Each target material was also irradiated by carbon ions to assess the importance of any possible competing reactions. Results of these calibration studies are presented in this paper.
