Design of proton beam optics for explosive detection system using accelerator

The system for detecting existence and position the explosive using accelerator is being developed. The gamma is produced by 1.75MeV proton through the Proton-Gamma reaction in 13C target, and the scattered gamma with 14N in explosive is detected by gamma detector. The system consists of accelerator, target, and detector. The required proton beam current is 10mA, which is determined by calculation. The large current proton beam can be accelerated in optical system, which is designed with simulation including space charge effect. The simple optical geometry is adapted for the optics design for the accelerator, and the details are reported in this paper
