The Experimental Study on the Impact of the Target Film Thickness to the Properties of the Neutron Tube

Neutron tube is a kind accelerator neutron source, which has been applied extensively. It is mainly composed of an ion source system, an accelerator system, and a target system. The target system is one of the most important parameters of the neutron tube, and it impacts directly the yield, the lifetime, and the stability. The pure titanium film was evaporated on the ceramic target by using the evaporation technique. The impact of the thickness of the titanium film on the yield of the neutron tube was studied, and the yield of the neutron tube was on optimistic state if the thickness of titanium film was 2.2μm. The properties of training and stability of neutron tubes with different thick titanium film target were also present in this paper.
