Abstract :
The results from experimental and three-dimensional computational studies of a radio-frequency structure for use in the CERN Linear Collider are presented. The structure would perform the function of converting beam energy from a UHF accelerated drive beam to 30-GHz radiation for powering the high gradient cavities of a second parallel beam, which would be accelerated to an energy of 1 TeV. Design considerations of this unusual component are discussed, along with the results of low-power radio-frequency tests on a scaled model which reveal the electrical characteristics of the structure. In addition, a comparison of the experimental findings with 3-D computations, performed with the MAFIA codes, is given, and good agreement is found. The results of tests with the structure excited by beams from the LEP (Large Electron-Positron Collider) preinjector linac are also presented. The transfer structure is found to satisfy many of the requirements needed for the role it would play in a two-beam accelerator
