Beam dynamics studies and parametric characterization of a standing wave electron linac

Abstract

This paper presents the results of electron beam tracking simulations for a 30 MeV standing wave electron linac at Electron Beam Centre Kharghar, Navi Mumbai, India. For the pulsed mode operation of the present linac preferential operation parameters have been determined from the results of beam dynamics studies. This electron accelerator is a general purpose facility for generation of Bremsstrahlung X-rays and neutron scattering experiments. This electron accelerator-based experimental neutron facility will be used for measurement of neutron crosssection (n,γ), (n, xn) and (n, f) reactions at different energies for various materials and material irradiation studies.

Design of a side coupled standing wave accelerating tube for NSTRI e-Linac

“…The tracking code utilizes non-adaptive Runge-Kutta integration of 4 th order [13]. This code is one of the codes that is commonly used to validate newer codes [28][29][30].…”

“…By considering the effect of space charge, about 43% of particles can reach to the end of the tube. Analysis of the final energy of the beam against the initial phase (figure 17) shows that particles in the phase between −100 • and 30 • reache to 6 MeV and the capture efficiency of the tube is more than 36% that is desirable in comparison to other standing wave tubes [7,29,32].…”
