  • Apparatus for electron beam irradiation of objects
    Patent number: 4492873
    Abstract: An apparatus for electron beam irradiation of objects comprises an electron beam shaper 1 providing a ribbon-shaped beam 7 and a deflecting electromagnet 8 with a frame-type magnetic circuit 9 to direct the beam 7 onto an irradiated object 6 substantially at an angle of 90.degree.. The deflecting electromagnet 8 has two poles 10, 11 extending over the width of the irradiated object 6 and two windings 12, 13 embracing the poles 10, 11 and connected to a direct current source 14, the deflecting electromagnet 8 being arranged so that the trajectories of the electrons within the area from the shaper 1 to the deflecting electromagnet 8 are inclined to the frame of its magnetic circuit 9.

  • Electron beam current stabilizing device
    Patent number: 4398132
    Abstract: Disclosed is an electron beam current stabilizing device comprising a sensing element (12) responsive to the beam current deviation from the predetermined value, a saw-tooth voltage shaper (14) connected to a high-voltage transformer (2) of an acceleration voltage source and providing periodic saw-tooth voltage, smoothly sloping portions thereof being shaped starting from the moment when the voltage at the high-voltage transformer (2) crosses zero, an adder (13) whose one input is connected to the output of the sensing element (12), and the other input, to the output of the shaper (14), a threshold element (15) connected to the output of the adder (13), a differentiator (16) connected to the output of the threshold element (15) to shape the electric driving pulses when the smoothly sloping portions of the saw-tooth voltage cross at the output of the adder (13) the threshold level of the threshold element (15), a light source connected to the output of the differentiator (16) to convert the electric driving pu
