Abstract

We have been developing a mine detection system coupled with a 1 MV compact tandem accelerator. This system will consist of a compact high current tandem accelerator, a target system, a detection system, a power generator system and a transportation system for mine field applications. The tandem accelerator is designed to accelerate protons with energies of 1.75 MeV up to a 10 mA beam current. We have developed a new mine detection method for a scattered 9.17 MeV gamma-ray produced from the ¹⁴N(γ,γ)¹⁴N photo-resonant reaction. The incident gamma-rays are produced by a 1.75 MeV proton beam bombarding at a ¹³C target. A new detection method is described which separates the scattered gamma-rays from the ¹³C target gamma-rays to within a 0.1% energy resolution using the Doppler effect from the nucleus recoil mechanism
