Abstract
Dense and uniformly distributed in volume ions due to uncompensated electrical charge can "explode", thus creating a directed beam of high-energy particles. The obtained energy during the Coulomb "explosion" can reach high values. It was determined that the energy values and time of the explosion depend on a number of particle system parameters such as charge, density, and dimensions. In this paper, the calculations of the "explosion" process using a dynamical approach for different configurations are presented: particle–particle, particles in cylindrical and spherical volumes. The "linearization" method is used for calculating the explosion time, particle velocity and energy. The correctness of the applied approach is shown in comparison with the traditional one. The calculations for the configurations are made using the necessary approximations. Numerical calculations are carried out for the case of the double size change.
