摘要：

A beam of 7Be4+ ions having E = 20.7 MeV and intensity 1.5×104 s-1 has been produced via the 1H (10B, 7Be)4He reaction. The beam had an energy resolution of 1.0 MeV FWHM, 1 cm spot size, and 3° angular divergence. The effect of a z-moveable secondary stop on beam purity was investigated. A 7Be4+ ion beam of E = 15.2 MeV, intensity 5×103 s-1, and similar energy resolution and emittance characteristics was produced via 12C(3He,7Be)8Be reaction. The maximum feasible 7Be secondary beams from these two reactions are extrapolated to be 5×105 s-1, respectively. Elastic scattering data for 7Be from Au and C targets are presented as an example of the use of this radioactive beam in secondary scattering experiments. © 1990.
