AbstractMultipactor discharges in dielectric accelerating structures are a major limitation on the performance of this otherwise very promising technology for future high energy physics machines and other applications. We will experimentally study a new approach, using a proper external solenoid field, to completely suppress multipactor. This approach has been theoretically studied and verified in a 3-D numerical simulation. The overall objective for the proposed Phase I program is the evaluation, design, and fabrication of DLA test structures for the high power multipactor experiments to be performed. Three X-band dielectric test structures (consisting of materials with different electronic properties) will be built, instrumented, and cold tested preparatory to high power measurements in Phase II. Applications and benefits: Eliminating multipactor effects in dielectric accelerators will allow higher power and higher efficiency operation of these machines. This will represent a great leap forward for the applications of dielectric materials in various particle accelerators and high power rf generation applications.
