Importance of a mirror based neutron source for the controlled fusion program

The importance of a neutron source for the controlled fusion program and the compatibility of mirror machines operating in a beam-target mode, with neutron source requirements is discussed. It is pointed out that the 2XIIB experiment has already established most of the feasibility characteristics of the neutron source. However, before a decision can be made to build a mirror machine source, additional experiments are needed to guarantee that the necessary improvement of plasma parameters can indeed be achieved.
