Abstract
A batch mode process has been developed to produce a 76Kr (T1/2 = 14.8 h) radioactive ion beam at the Lawrence Berkeley National Laboratory 88-in. Cyclotron. First, a 6 particle ?A ? beam is run for 17 h to produce approximately 101476Kr atoms via the reaction 74Se(?, 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. © 2004 Published by Elsevier B.V.
