The LEP Superconducting RF System
The basic components and the layout of the LEP rf system for the year 2000 are presented. The superconducting system consisted of 288 four-cell cavities operating at 352 MHz powered by 36 klystrons providing on average of 0.6 MW of rf power. This system was complemented by 56 cavities of the original copper rf system. A total accelerating voltage of 3630 MV could be provided routinely allowing ...
متن کاملSuperconducting RF Cavities: Past, Present and Future
In the last two decades many laboratories around the world, notably Argonne (ANL), TJNAF (formerly CEBAF), CERN, DESY and KEK, undertook the development of the technology of superconducting (SC) accelerating cavities. The aim was either to increase the accelerator energy or to save electrical consumption or both. This technology has been used extensively in the operating machines showing good p...
متن کاملLarge-grain Superconducting Rf Cavities at Desy
The DESY R&D program on cavities fabricated from large-grain niobium explores the potential of this material for the production of approximately 1000 nine-cell cavities for the European XFEL. The program investigates both basic material properties, comparing large grain material to standard sheet niobium, and material availability, production, and preparation aspects. Several single-cell caviti...
متن کاملBasic Principles of RF Superconductivity and Superconducting Cavities
The basics of superconductivity are outlined with special emphasis on the features which are relevant for the application of superconductors in radio frequency cavities for particle acceleration. For a cylindrical resonator (“pill box cavity”) the electromagnetic field in the cavity and important parameters such as resonance frequency, quality factor and shunt impedance are calculated analytica...
متن کاملRf Control System for Isac Ii Superconducting Cavities
The first phase of the ISAC II project consists of the acceleration of radioactive ions by 20 superconducting DTL's with a total effective voltage of ~20MV. Each of these cavities will be powered at a frequency of 106.08 MHz to a maximum field gradient of 6 MV/m. With unloaded cavity Q's of ~10, the RF control system for these superconducting cavities is based on a self-excited feedback loop. T...
