e Adelphi generator is approximately 18 in. in length and 10 in. in diam-
eter; it emits 1 × 10

n/s. Some customers are concerned with the high cost
of approximately $300,000; however, this cost is acceptable considering the
source strength one can get for it.
e Berkeley Lab neutron generators consist of RF-driven plasma ion
sources, extractors of various designs, acceleration electrodes, and titanium-
covered targets. Conventional generators are usually short-lived because the
target’s isotopes are quickly consumed. e target in the Berkeley Lab genera-
tors, however, is constantly replenished by ions from the plasm ...
