Development of the New Electron Gun for Electron-Beam Welding With Help of WinSAM Program | |
|
||
| New WinSAM program for simulation of electron-optical systems and electron guns was created in BINP. This program is the further development of SAM code. The main advantage of WinSAM program is the new interface that greatly simplifies the usage of the program. The other main targets are enlargement of the scope of solved tasks, introduction different analytical fields, development of enhanced emission model, and speed up calculations. New 120 kV multi-electrode electron gun for electron-beam welding is developed with help of WinSAM program. The required beam current in welding mode is up to 30 mA, in diagnostic mode is 1 mA. Beam radius at welding point should be less than 0.3 mm. Proper electron-optical system of this gun was obtained during numerical simulations. The calculations take into account transversal beam temperature and space charge compensation in region after small aperture anode. Production of this electron gun is started. | ||
