摘要
There are many important applications for very intense positron beams (≥ I Ci of e+); however, the radioactive sources needed to produce these beams are not readily available. Two separate processes for fabricating inexpensive, intense positron sources from 22Na and 58Co have been investigated. Both procedures have been successfully tested with low levels (mCi) of activity.
