KIGAM has developed a nanosecond bunching system to obtain the reliable neutron capture cross section data. The pulsed beam is obtained by a set of deflector electrode and slit. Also the bunched beam is obtained through the three stage electrodes, to which double bunching principle applies. The specification of neutron bunching beam is designed to be that the repetition rate is 8 MHz, the width is about 2 ns, and duty factor is about 20 %.
