The quality of EBWelds, realized by a 90° deflected Electron Beam, depends on operator defined parameters of the welding equipment, like gun voltage and current, beam centering, focus current(s), bending magnet current, welding ...
We present the design, simulation and analysis of 400 kW sheet beam gun. The beam optics, beam envelop and the magnetic field of the gun is designed and then simulated in CST PS. 100% beam transmission is achieved at the target ...
Plasma-based ion implantation (PBII) method is a technique that allows uniform ion implantation to a sample by applying a negative voltage to the model to draw and accelerate ions in the ion sheath existing around the piece. ...
The Plasma-based ion implantation (PBII) method is capable of low-temperature and short-time sterilization. In this study, we investigated the sterilization effect of PBII treatment on Gram-positive and Gram-negative bacteria’s ...
