Progress Report on High - Gradient Rf Studies in Copper Accelerator Structures
نویسنده
چکیده
This paper is a progress report on studies carried out at the Stanford Linear Accelerator Center to understand the behavior of copperaccelerator structures under extreinely high RF fields. Such structures are being designed for future electron-positron linear colliders. Recent studies include field emission and breakdown experiments with an S-band slotted-disk structure, a single demountable S-band cavity and a short X-band structure which has not yet been tested. The demountable cavity was built specifically to examine the effects of copper quality, surfacesonditioning, gaseous exposures, and surface damage. R.esuits to date and recent theoretical conjectures are discussed. Introduction

HIGH - GRADIENT STUDIES ON 11 . 4 G # z COPPER ACCELERATOR STRUCTURES
This paper is a progress report on studies carried out at SLAC to assess the high-gradient behavior of 11.4 GHz copper accelerator structures for future linear colliders. The structures which have been examined in the last year are a 7-cavity standing wave (SW) section and a 30-cavity traveling-wave (TW) section. Both st&tures are of the constant-impedance uniform-aperture iype with a m phase s...
متن کاملRf Breakdown in X-band Waveguides∗
Next generation of linear accelerators will have multimegawatt rf systems. The RF system of the Next-Linear Collider (NLC) will have hundreds of waveguide components and high-gradient accelerating structures. Waveguide components should reliably handle up to 600 MW of a 400 ns, 11.424 GHz rf pulse [1]. RF breakdown at such high power could damage these components. For example, breakdown damage ...
متن کاملThe next Linear Collider Test Accelerator+
During the past several years, there has been tremendous progress on the development of the RF system and accelerating structures for a Next Linear Collider (NLC). Developments include high-power klystrons, RF pulse compression systems and damped/detuned accelerator structures to reduce wakefields. In order to integrate these separate development efforts into an actual X-band accelerator capabl...
متن کاملCLIC status and outlook
The Compact Linear Collider study (CLIC) is in the process of completing a Conceptual Design Report for a multi-TeV linear electron-positron collider. The CLIC-concept is based on high gradient normal-conducting accelerating structures. The RF power for the acceleration of the colliding beams is produced by a novel two beam acceleration scheme, where power is extracted from a high current drive...
متن کاملAn acoustic sensor system for localizing RF breakdown in warm copper accelerating structures
X-band accelerator structures meeting the Next Linear Collider (NLC) design requirements have been found to suffer damage due to Radio Frequency (RF) breakdown when processed to high gradients [F. Le Pimpec, et al., in: LINAC 2002, Korea, SLAC-PUB-9526, 2002 [1]]. Improved understanding of these breakdown events is desirable for the development of structure designs, fabrication procedures, and ...
