A: 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 180 • . 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/cm 2 , 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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
