MECHANICAL DESIGN CONSIDERATIONS OF A STANDING WAVE S-BAND ACCELERATOR WITH ON-AXIS COUPLERS

The need for high efficiency rf accelerating structures operating at room temperature has been fulfilled for certain applications by standing-wave coupled-cavity accelerators, the side-coupled struc1 ture operating in the n/2 mode being an example. 1-4 Considerable development work has been carried out on the design and fabrication of 0.8 GHz sidecoupled structures resulting in the establishment of assembly criteria and procedures.
