Thanks for making my point.

Accelerators are used to accelerate charged particles (ions)
which then interact with targets to produce neutrons. The
neutrons are _not_ accelerated because being neutral they cannot
be accelerated by electric or magnetic fields.

It should be noted that when using fusion propulsion systems for
deep space travel one uses reactions such as Deuterium-Helium 3
to produce very energetic charged particles and to minimize the
number of neutrons produced.
