Electron Linear Accelerator

The electron linear accelerator (KURRI-LINAC) is used as various types of particle beam source, i.e. electrons, neutrons, and photons. The electron beam is generated by a thermionic gun and accelerated to a maximum energy of 46 MeV in two accelerator tubes by L-band (1.3 GHz) microwave. The pulse width is variable from 2 ns to 4 μs. A low energy beam below 10 MeV, an ultra-low current beam by field emission, and a single-bunched beam are also available. The research region covers a wide field of nuclear data acquisition with the neutron time-of-flight method and a lead slowing-down spectrometer, isotope production by the (γ,n) (γ,p) reaction, low-temperature electron irradiation, a photon activation analysis, and a spectroscopy with coherent THz radiation.
