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 ...
We fabricated high performance cold cathode electron beam with carbon nanotube (CNT) emitters. High performance cold cathode electron emitters show more than 150 mA electron emission current and long-time operational stability. ...
In the paper is presented multicolumn e-beam lithography (MCL) system intended generally for production of templates.
The system was designed in two versions: with Schottky emitter and LaB6/CeB6 emitter.
System with Schottky ...
Cobalt, as one of the “critical” and “strategically important” metals, plays a key role in the contemporary development of the world’s industry. Cobalt has specialized applications where it is currently impossible ...
https://epluse.ceec.bg/wp-admin/poThe technology of cable insulation radiation modifying had a wide application in the industry. The use of such a technology provided the production of a wide range of cables, wires and heat ...
The management of the quality during electron beam welding directed to optimization of the process parameters is an important way to improve the use of the expensive equipment and to make the EBW process more efficient in consuming materials, time and energy.

Electron beam welding (EBW) presents significant advantages in terms of welding performance when compared to other welding processes due to its small spot size, low divergence, high power density and low heat input. It is ...
The quality of electron beam welds depends upon a number of parameters like accelerating voltage, beam current, focus settings, vacuum level, working distance and welding speed. Even if these parameters are tightly controlled, ...
Measurements of electron beam profiles always had an academic touch in the past. New standards and faster image processing make the beam characterization more and more a quality tool in production and allow transfer of beam ...
