Abstract: A magnetically confined sheet beam has been designed and tested for its uniform transmission. The beam is fully immersed in a uniform magnetic field of 50 Gauss which bends and focuses the beam throughout in a uniform laminar flow at 180o. A sheet beam of uniform cross section (0.35 cm × 12.5 cm) successfully has been tested; the width of the beam is many times the thickness. The gun is designed and simulated in CST software. The beam is uniform throughout with parameters; current density, emittance and perveance values; 1.04 A/cm2, 14 π-mm-mR and 5 μAV−3/2, respectively. The simulation and test results are in agreement. The first application is the evaporation of refractory metals for coating in the field of nanotechnology and also expected to be used in klystrons for advanced particle accelerators and colliders at higher acceleration potentials.
