摘要： An angle measurement system for an ion beam includes a flag defining first and second features, wherein the second feature has a variable spacing from the first feature, a mechanism to translate the flag along a translation path so that the flag intercepts at least a portion of the ion beam, and a sensing device to detect the ion beam for different flag positions along the translation path and produce a sensor signal having a first signal component representative of the first feature and a second signal component representative of the second feature. The first and second signal components and corresponding positions of the flag are representative of an angle of the ion beam in a direction orthogonal to the translation path. The sensing device may be a two-dimensional array of beam current sensors. The system may provide measurements of horizontal and vertical beam angles while translating the flag in only one direction.
