The fast ignition scheme is recognized as a potentially promising approach to achieve the high-energy-gain target performance needed for commercial inertial confinement fusion. The hot spot heating process by an assumed deuteron beam is evaluated in order to estimate the contribution of the energy produced by the deuteron beam-target fusion to the heating process. So, deuteron beam was considered with Maxwellian energy distribution at temperature of 3MeV. Then, the deuteron energy loss and range, Includes Coulomb and nuclear elastic interactions, in the uniformly pre-compressed fuel, with density 300gcm-3, were calculated. By calculating the contribution of alpha particles produced by the athermal nuclear reactions and nuclear elastic scattering, power deposition of deuteron beams increased up 6% compared with the fast ignition by similar ion beams. This can lead to reduced energy delivered by the external beam.
