Abstract
A batch mode process has been developed to produce a 76Kr ( T 1 / 2 = 14.8 h) radioactive ion beam at the Lawrence Berkeley National Laboratory 88-in. Cyclotron. First, a 6 particle μA α beam is run for 17 h to produce approximately 1014 76Kr atoms via the reaction 74Se(α, 2n)76Kr. Then, the krypton is separated from the target material and injected into the AECR-U ion source. Beam intensities as high as 3×108 particles per second are observed with an integrated beam current of 6(2)×1011 particles per 24-h batch cycle.
