    Abstract: A circular target having a copper backing and a front target face material of scandiumtritide is mounted with its face perpendicular to the axis of an elongated member which is pivoted through a center hole of an end plate of a cup-shaped member wherein the center hole coincides with the longitudinal axis of an axial ion beam. A screw member having an off-center hole is adapted to threadedly engage the interior threaded walls of the cup-shaped member and through which the elongated member also passes. The rotation of the screw causes the target to revolve around the longitudinal axis of the ion beam at a varying radius as measured from the ion beam, such varying radius being a function of the rotation of the screw member. This causes the ion beam to trace a spiral pattern upon the target face. In an alternative embodiment, the elongated member is also pivoted at a median point along its length but passes through an off-center hole in a disc which is captured but free to rotate within a ring screw adapted to threadedly engage the interior walls of the cupshaped member. This embodiment provides a concentric circle pattern on the face of the target in conjunction with the ion beam.

    Abstract translation: 具有铜背衬和钪二氧化铅的前目标面材料的圆形靶被安装成其表面垂直于细长构件的轴线，该细长构件的轴线通过杯形构件的端板的中心孔枢转，其中中心孔重合 轴向离子束的纵向轴线。 具有偏心孔的螺钉构件适于螺纹地接合杯形构件的内螺纹壁并且细长构件也通过该螺纹构件。 螺杆的旋转使得靶以离子束测量的变化的半径围绕离子束的纵向轴线旋转，这种变化的半径是螺杆构件的旋转的函数。 这导致离子束在目标面上追踪螺旋图案。 在替代实施例中，细长构件也沿着其长度在中间点处枢转，但是穿过盘中的偏心孔，其被捕获但在环形螺钉内自由旋转，该环形螺钉适于螺纹地接合杯的内壁 形成员 该实施例在离子束结合物体的表面提供同心圆图形。
