This paper describes the latest developments in neutron sources developed for fast neutron therapy. Two approaches have been taken using cyclotrons and D-T generators. For cyclotrons the proton on beryllium reaction is now preferred since smaller cyclotrons for a given neutron penetration can be used.

A ScD2 target film 5×10-5 m thick, tested in a UHV compatible 200 keV deuterium accelerator baked to 470°C, maintained a D-D neutron output rate of 1.0-1.2×1011 /s for 80 out of 140 hours of operation. This result demonstrates that a D-T neutron generator capable of a neutron output rate of 1×1013 /s and having a target lifetime suitable for cancer ...

Many research activities, instrumental analysis, studies of radiation damage, etc., require neutron sources. The main neutron sources present in Italy are described in three different sections: nuclear research reactors, accelerator driven, and metrology stations.

Review of Scientific Instruments, 1955
A pulsed neutron source is described which gives 106 neutrons in a burst which is 2×10−8 second wide. The plasma of an ion pump is used as the source of deuterium ions which are accelerated to 200 kv before striking a deuterium target, where the D(d,n)He3 reaction produces 2 to 3 Mev neutrons.

Publisher Summary This chapter discusses the neutron sources. All neutron sources are based on nuclear reactions that free neutrons bound in nuclei. These are categorized according to the mechanisms by which this is done: fission chain reactions, fusion reactions, e--bremsstrahlung-induced photoneutron and photofission reactions, charged-particle ...
