Abstract

We have developed a technique to measure the position of thin target foils (≤ 10 μm/cm2) during irradiation with an accuracy of ∼ 7 μm. The experiment makes use of a kinematic coincidence technique, recording the scattered as well as the recoil particles in a precisely known geometrical setup. For 3 μm/cm2 carbon foils bombarded by 4 MeV 12C2+ ions, target foil movements of about 4 μm/h were observed.
