✦ Synopsis

A batch mode process has been developed to produce a 76 Kr (T 1=2 ΒΌ 14:8 h) radioactive ion beam at the Lawrence Berkeley National Laboratory 88-in. Cyclotron. First, a 6 particle mA a beam is run for 17 h to produce approximately 10 14 76 Kr atoms via the reaction 74 Se(a, 2n) 76 Kr. Then, the krypton is separated from the target material and injected into the AECR-U ion source. Beam intensities as high as 3 Γ‚ 10 8 particles per second are observed with an integrated beam current of 6(2) Γ‚ 10 11 particles per 24-h batch cycle.

In the framework of the production of radioactive alkali ion beams by the isotope separation on-line (ISOL) method in SPIRAL I, a surface ionization source has been developed at GANIL to produce singly-charged ions of Li, Na and K. This new source has been designed to work in the hostile environment
