Abstract :
Many button type and strip line type beam position monitors are employed in the South Hall Ring (SHR) at MIT-Bates. It is desired to calibrate and routinely check the readouts of those monitors by simulating the beam. A wire setup was built to serve this purpose. It consists of a button type beam position monitor body with a wire running through it. To eliminate end-effects both ends are extended with 10 inch long uniform beam pipes. RF matching is carefully performed with ECCOSORB AN 75 microwave absorber forms. The wire is positioned 3 mm offset with respect to the X-pair buttons and symmetric with respect to the Y-pair buttons. Thus the same setup can be used to check both sensitivity and zero-offset
