Abstract

Measurements of ion-induced nuclear reactions have been used to diagnose ion acceleration from the interaction of high- intensity ( gt 10(19) W cm(-2)) laser light with solid targets. Nuclear activation of catcher materials surrounding the interaction region has been studied using a high-resolution germanium detector. It was found that, when a 100 mum thick Al target foil was preheated, the proton flux produced from the laser-foil interaction was considerably reduced. Observed heavy-ion-induced reactions are used with calculated reaction cross sections to quantify ion acceleration.
