Electron beam controlling means

The utility model discloses an electron beam controlling means, include: electron accelerator produces corresponding electron beam and draws forth through grid and titanium film, the electronic beam current of treating the detection is drawn forth to multiunit through -hole through setting up on the grid, through with each the through -hole matched with of group scanning border detection device in order whether to surpass the scanning border and detect drawing forth the electron beam in real time, through the scanning control system regulation scanning coil's with scanning border detection device communication connection parameter, and then the fast scanning border size of adjustment electron, it is big or small to adjust the line through the line control system who is connected with detection device, reaches the line and stably draws forth the effect in real time, reaches real time kinematic monitor effect simultaneously. The utility model provides an electron beam controlling means is through the on line me
