Description
Summary:A high-yield D–T neutron generator has been developed for neutron interrogation in homeland security applications such as cargo screening. The generator has been designed as a sealed tube with a performance goal of producing 5×1011n/s over a long lifetime. The key generator components developed are a radio-frequency (RF) driven ion source and a beam-loaded neutron production target that can handle a beam power of 10kW. The ion source can provide a 100mA D+/T+ beam current with a high fraction of atomic species and can be pulsed up to frequencies of several kilohertz for pulsed neutron generator operation. Testing in D–D operation has been started.
