technical field

The invention relates to the technical field of neutron generators, in particular to a neutron source with ion beam guiding function.

Background technique

A neutron source generally consists of an ion source, an accelerating electrode and a neutron target. The ion source ionizes deuterium gas or deuterium-tritium mixed gas into ions, which are extracted from the ion source extraction hole.
