For high-power operation of charged particle rf accelerators, the input coupler windows must withstand enormous stresses due to charging induced by the highenergy charged particle beam passing by and high rf power passing through. Simx most couplers use a single coupling aperture, harmfid asymmetrical rf kick on the beam at the coupler-cavity interface exists. If this problem is solved by dual cxmpIing, the size of the structure becomes a problem. The almve problems are considered common to

In superconducting structures, since the frequency of operation is usually around 1 GHz, compactness of the coupler is also a great concern for the cryostat design. Two new waveguide coupler designs that may solve the above-mentioned problems are discussed.
