Abstract: The proposed intense 14 MeV neutron source at IPR is accelerator based using the T(d,n) reaction. This facility will be indigenously built and used for the fusion Neutronics studies. Deuterium ions will be accelerated up to 300 keV in an electrostatic acceleration column delivering a maximum beam current of 20 mA. The beam will be made to impinge a water cooled, rotating tritium target. The expected neutron yield will be ~1012 neutron per second. This paper describes the preliminary design of the neutron generator and the MCNP model results of the shielding calculations. The calculation of dose rate has been carried out for the optimum thickness of concrete shield.
