Abstract :
The AmPS (Amsterdam Pulse Stretcher) is a 900-MeV electron storage and stretcher ring. Its construction started early 1991. A fast-response, high-resolution stripline-type beam position monitor has been developed for the ring. The monitor has a quasi-elliptic cross section. Its sensing strips have a length of lambda /4; the operating frequency is 2856 MHz. The mechanical construction, the matching of the output ports, and the online calibration system are described. The results of bench measurements as well as measurements with a 500-MeV beam are also presented.<>
