Abstract
A prototype magnetic positron beam was built in order to study the fea sibility of using low energy (almost-equal-to 1-2 MeV) deuteron accele rators to produce moderate-intensity (almost-equal-to 10(7)-10(8) e+/s ) monoenergetic low energy positron beams. Graphite and diamond target s were bombarded with a few muA of deuterons at energies of 0.9, 1.3 a nd 1.8 MeV to produce the short lived N-13 beta+ emitter. The results show that the peak beta+ activity per 1 muA of deuteron irradiation is about 1 mCi. When combined with a standard positron moderator, this m ethod of producing low energy positrons is expected to be capable of y ielding a beam of up to 10(8) e+/s.
