Abstract
A compact high-resolution RBS system consisting of a 90o sector magnetic spectrometer (radius 200 mm), a quadrupole lens, an electrostatic deflector and a one dimensional position sensitive detector (length 100 mm) has been developed. The measured energy resolution of the spectrometer is 0.11% of the analyzing energy at an acceptance angle of 0.3 msr including the energy spread of the incident ion beam. Some observations using this new system are presented.
