Abstract

The design of the Main Injector beam position monitor (BPM) was driven by the desire to minimize its begun impedance and longitudinal space requirements. The resulting BPM consists of four striplines inset into a section of Main Injector beam pipe. The striplines are combined in pairs to form either a horizontal or a vertical BPM by switches located nearby in the tunnel. The BPM response is decidedly non-linear and furthermore shows sensitivity to the beam position on the orthogonal axis. This paper presents the method in which consecutive measurements in both planes are used to derive the actual (x,y) position in an online environment
