Need and Fabrication of Self-Supporting Thin Targets in Medium Mass Region

Self supporting very thin feasible targets of iron, vanadium, chromium of thickness 700 μg/cm2, 600 μg/cm2, 800 μg/cm2 respectively, have been fabricated by using different techniques thermal evaporation and rolling method at Tata Institute of Fundamental Research, Mumbai. Freshly prepared self-supporting target in the mass region A ~50-60 fulfill one of the strong need of neutron induced cross-section measurement by direct particle counting method and by surrogate method, which play a significant role in fusion reactor technology. Neutron induced reaction having high requirement in fusion reactor application have been studied with maximum energy of the outgoing particle and energy loss within the target by using TALYS-1.9 and SRIM code respectively. TALYS-1.9 and SRIM-2008 calculations optimize the thickness of the target in order to reduce the energy loss and self absorption of outgoing particle in the sample materials.
