CEBAF's new RF separator structure test results

Prototypes of the RF separator for CEBAF have been made and successfully beam tested. The structure is a new design which has a high transverse shunt impedance together with a small transverse dimension compared to more conventional RF deflecting structures. Five RF separators will be used at CEBAF to allow beam from any one of the five recirculation passes to be delivered to any of the three experimental halls. We have already described the basic design of the structure and theoretical calculations. We have also reported some results from RF measurements and beam tests. In this paper we present more beam test results, our final design parameters, and test results of coupling two 1/2 wavelength cavities together.<
