    • Electron beam is focussed in a focussing column in a high vacuum environment and emitted downward through upper, middle, and lower orifices. A second stage vacuum duct concentrically surrounds a lower portion of the beam focussing column and separates the upper and middle orifices. A first stage vacuum duct concentrically surrounds the second stage vacuum duct and separates the middle and lower orifices. An outer wall surrounding the second duct tapers downward to the lower orifice, allowing it to be positioned as closely as desired to a workpiece regardless of surface topography. The apparatus comprises an orifice housing having an internal cavity which receives the lower part of the beam focussing column, an inner wall which defines the outer boundary of the second duct, and a support spool borne against by the outer wall, which is fixed to the bottom of the orifice housing and fixes the other components relative to each other in the housing.
    • 电子束在高真空环境中聚焦在聚焦柱中,并向下通过上,中,下孔。 第二级真空管同心地围绕梁聚焦柱的下部并分离上孔和中孔。 第一级真空管道同心地围绕第二级真空管道并分离中部和下部孔口。 围绕第二管道的外壁向下逐渐变细到下部孔口,使得它可以根据需要尽可能地紧密地定位在工件上,而与表面形貌无关。 该装置包括具有内腔的孔口壳体,该内腔容纳梁聚焦柱的下部,限定第二管道的外边界的内壁和由外壁承受的支撑阀芯,该支承阀芯固定到 孔的底部并且在壳体中相对于彼此固定其它部件。
