Dispersion of metal microdrops exposed to an electron beam with dynamical retention in an electrostatic trap

The process of obtaining nanoparticles of pure metals by melting down initial powder particles using the infrared emission and by charging them electrically in an electron beam with the subsequent splitting them to nanodrops is investigated numerically. The possibility of a substantial increase in the duration of the drop’s stay in the working zone due to the effect of an electrostatic trap is shown, which allows the requirements for the electron beam to be lowered, the range of initial conditions to be extended, and the stability of the process as a whole to be enhanced by implementing the cascade splitting of drops of all sizes in a single regime.
