MAKING OF n_TOF TARGET GEOMETRY,ENERGY DISTRIBUTION & NUTRON SPALLATION STUDY USING FLUKA

Abstract

This Thesis consists on making of n_TOF target geometry, energy distribution & Neutron spallation using FLUKA Monte Carlo simulation. The accuracy of the Monte carlo code falls on the accuracy of the probability distribution, it means the physical models implemented in FLUKA and the experimental data from ENDF(Evaluated Nuclear Data File, USA), JEFF (Europian data file), JENDL(Japan) etc. used for the multi-algorithm for transport of lowenergy neutron. in the FLUKA manual most work in the design and development has been the placed and improved of sound and modern physical models. Microscopic models are used when possible, consistency between reactions is ensured, conservation laws are enforced and the results are compared with experimental data.it is the advantage of this simulation that Where no experimental data are available, predefined library is provided by the code for expected data . As a result the predictions are obtained with a minimal set of free parameters for energy, targeted projectile combinations. In this thesis we have shown that how geometry is formed using fluka, because this is just a introduction of fluka and just demonstrate energy distribution & Neutron spallation. It gives us useful data for using the proton beam or for other beam for application in some medical or some other experimental use. for performing a experiment regarding a particle physics it cost much money that’s why it’s better to use real simulation like FLUKA for better understanding regarding the particle interaction.
