Results of irradiation of thin Chemical Vapor Deposition (CVD) diamond detectors with low energy: p, \alpha and 7Li beams are presented. Energy resolution: \Delta E/E<1 \% of a single crystal detector was achieved. A coincident measurement with two diamond detectors showed time resolution of 100 ps and efficiency above 70 \%. Despite a high beam flux reaching 109 particles/s cm2 the tested detectors showed low dead-time and satisfactory radiation hardness. Perspectives of applying thin CVD diamond detectors in monitoring of a slowed down radioactive beam (RIB) are discussed.
