Abstract

PURPOSE: To relieve necessities to moving toleration area in Z direction of material surface by controlling to keep the focus of the electron beam in fixed relation with material surface to be applied and controlling the amplitude of the beam fixedly.
CONSTITUTION: Electron beam 1 is focussed on surface of material 4 through coil 3. Z direction driving mechanism 6 as well as inside x-y driving mechanism is disposed on a stand 5 mounting the material 4. Surface position of the material near beam applying point is detected by Z direction detector 7 such as laser interference meter to control the mechanism 6 and to control the position in Z direction due to make beam focus on the surface. Or, by the output of detector 7, current of the coil 3 is controlled at 8 to coincide the focus with surface of the material 4. At the same time, by the result of detection, a beam deflecting inclination plate 10a is controlled to fix the amplitude of beam on the surface of material 4. Thus, as the half-vertical angle can be enlarged, by applying high energy density, shortening of working time and improvement of stabilization of the apparatus is obtained.
