Abstract: Tungsten is being proposed as a front runner choice for the plasma facing component material of next generation fusion reactor because of its superior thermo-physical and mechanical properties. It is essential to study the ion material interaction for its response to severe conditions of fusion reactor. In this work, an ingenious ion source namely plasma focus is used to study the effect of neon irradiation on tungsten under various experimental conditions. Exposed and reference tungsten samples were analyzed using optical microscope, scanning electron microscope, atomic force microscope. Surface analyses confirm the formation of micro-cracks, bubbles, blisters, holes etc. X-ray diffraction pattern confirms the development of compressive stress on the sample due to thermal load and formation of other phases or some expanded phases
