Contribution

It introduces a novel electrostatic charge state analyzer and a custom bipolar power supply, both designed for MeV ion collision studies, with simulation and experimental validation.

Findings

Successful design and simulation of the CSA using SIMION

Effective testing with proton and carbon ion beams at 1.7 MV

Enhanced capability for charge state detection in high-energy collisions

Abstract

We have developed a post-collision projectile charge state analyzer (CSA) for detecting the charge state of the projectile ion following ion-atom/molecule collision. The design of the analyzer, based on electrostatic parallel plate deflector was simulated using SIMION ion optics package. We have also developed a 10 kV bipolar programmable power supply to bias the CSA electrodes. The CSA and the power supply, both, were tested in collision studies using MeV energy ion beam of proton and carbon ions at the 1.7 MV tandetron accelerator facility at IIT Kanpur.
