The final goal of plasma physics research today is to achieve controlled thermonuclear fusion for generation of power. One of the major problems for the achievement of this goal is to heat the plasma to a high temperature. Among other various techniques applied, the heating of plasma by relativistic electron beam is a significant one. Hence this generation of the experiments in REB - plasma interaction aim to understand the physics of interaction mechanism and transfer of energy from beam to plasma. Neutral beam diagnostics to measure density and ion temperature of the plasma are discussed. This discussion is divided into three parts: (1) Attenuation of monoenergetic neutral beam passing through the plasma is used to measure the density of the plasma; (2) Charge-exchanged high energy neutrals are energy analysed and their intensities measured to get the ion temperature of the plasma; (3) a multi energy neutral beam attenuation is measured to evaluate the ion temperature profiles of the plasma with better accuracy than that of charge exchange measurements. Some of the important design criteria are discussed, and some preliminary results are presented.
