The objective of this Master's thesis was to design and construct a velocity-map imaging spectrometer to measure the electron and ion momentum distribution of a molecular gas beam which is ionized by a pulsed laser beam. Velocity map imaging is technique to study the complete kinematics of a chemical reaction. 3D momentum distribution of ions are recorded on a 2D detector.The project involves designing and simulations. Simulations of electron and ion trajectories in an electric field has been made using a software SIMION and the dimensions of the spectrometer and electrodes has been designed with suitable voltage settings of the electrodes so as to focus the ionsonto the 2D detector. And based on this simulation, the entire velocity map imaging setup has been constructed. The method works for both electrons and ions.
