Superconducting Nine-Cell Cavities for TESLA
The Tera Electronvolt Superconducting Linear Accelerator TESLA is the only linear electron-positron collider project based on superconductor technology for particle acceleration. In the first stage with 500 GeV center-of-mass energy an accelerating field of 23.4 MV/m is needed in the superconducting niobium cavities which are operated at a temperature of 2 K and a quality factor Q0 of 10 . This...
متن کاملImproved Surface Treatment of the Superconducting TESLA Cavities
The proposed linear electron-positron collider TESLA is based on 1.3 GHz superconducting niobium cavities for particle acceleration. For a center-of-mass energy of 500 GeV an accelerating field of 23.4 MV/m is required which is reliably achieved with a niobium surface preparation by chemical etching. An upgrade of the collider to 800 GeV requires an improved cavity preparation technique. In thi...
متن کاملTesla Superconducting Accelerating Structures
The application of the superconductivity phenomenon in accelerators originated with pioneer work in the late sixties at the High Energy Physics Laboratory (HEPL) at Stanford University [1]. Starting with the deposition of lead on copper and niobium on copper, by the end of 1968 the HEPL group had developed and tested the first bulk niobium superconducting accelerating cavity [2]. The result was...
متن کاملTrapped Modes in Tesla Cavities
In the TESLA linear collider scheme [1] the existence of trapped modes [2] within a TESLA cavity could be a severe problem to be overcome. Damping of trapped modes seems impossible due to their localization within the cavity, which prevents a coupling to the HOM dampers mounted to both ends of the beam pipes. As a consequence the energy of a trapped mode can achieve considerable values after se...
متن کاملSuperconducting cavities for accelerators
Superconducting cavities have been in operation in accelerators for 25 years. In the last decade many installations in storage rings and linacs have been completed. Meanwhile, nearly 1 km of active cavity length is in operation in accelerators. Large-scale applications of superconducting radiofrequency systems are planned for future e+e− linear colliders and proton linacs. Superconducting cavit...
