About simulation magnetically shielded electron-optical systems forming convergent sheet electron beams

A method of synthesis is developed, equations are derived and results are obtained via this method for simulation of magnetically shielded electron-optical systems that form sheet electron beams with compression. Relation that allow determination of the parameter of the electron guns and deformation of cross-section sheet electron beams in the magnetic field are presented Electron-optical systems with linear compression ∼10 and current density ∼ 100 A/cm
²
of sheet electron beam are designed.
