Abstract

In this research project, we investigate the Time of Flight (ToF) spectrum of ionic H2 fragments who are created in collisions between high-energy Sn ions and H2 molecules. CHEOPS, the experimental setup used to investigate such interactions is equipped with a ToF spectrometer to perform mass spectrometry on the ionic H2 fragments. Besides determining the detection efficiency for the ionic fragments, we aim to measure kinetic energies involved in the collision. To achieve this goal, a model of the experimental setup is constructed using SIMION. Particle trajectories are then simulated, and benchmarked to experimental data.Flight times of the ions are excellently reproduced. The transmission and detection efficiencies which differ significantly from simple analytical approximations are in fair agreement and in much better agreement than the analytical results
