Rotating Neutron Target System

A D-T neutron target system with a 30- to 40-hour half-life has been developed that yields 1 to 2 × 1012 neutrons per sec. This system uses a target that is rotating at 1100 rpm. The good success of this system indicates that this type of target system may be capable of being used at much higher beam power levels. Calculations indicate that a beam power of 100 kW and a beam density of 10 kW/cm2 can be handled with a front target temperature of less than 250°C.
