| Abstract: | Working principle and structure and debugging process of a mobile accelerator are introduced. The mobile accelerator, compact and light-weighted, can produce beam currents with high stability and small spot, and it is used in experiment of fast neutron imaging in our academy for the first time. In application process, some parameters including the beam current stability parameter are measured. Successive neutron yield is measured using concomitance particle means. Elementary images are acquired to fit the accelerator and the digital imaging system together． |
