First in-beam experiment in K500 superconducting cyclotron at VECC

Abstract

Characterization of first beam from K500 cyclotron at VECC, Kolkata, was performed using the elastic scattering experiment with a ¹⁹⁷Au target. Two independent approaches have been used to calibrate the detector system to estimate beam energy and its energy spread. Apart from the beam characterization, the fragment emission mechanism, particularly the isospin equilibrium and isoscaling behaviour, has been studied using ¹⁴N, ¹⁶O and ²⁰Ne beams from the cyclotron. This article provides details of the beam characterization of the cyclotron and also an overview of the experiments conducted.
