RF-Breakdown in High-Frequency Accelerators
نویسندگان
چکیده
RF breakdown in high-frequency accelerators appears to limit the maximum achievable gradient as well as the reliability of such devices. Experimental results from high power tests, obtained mostly in the framework of the NLC/GLC project at 11 GHz and from the CLIC study at 30 GHz, will be used to illustrate the important issues. The dependence of the breakdown phenomena on rf pulse length, operating frequency and fabrication material will be described. Since reliability is extremely important for large scale accelerators such as a linear collider, the measurements of breakdown rate as a function of the operating gradient will be highlighted. Invited talk, presented at the 2004 IEEE Power Modulator Conference (26 Power Modulator Symposium and 2004 High Voltage Workshop) San Francisco, CA, May 23-26, 2004 Work supported by Department of Energy contract DE–AC03–76SF00515 RF Breakdown in High Frequency Accelerators

Effect of RF Parameters on Breakdown Limits in High-Vacuum X-Band Structures
RF breakdown is one of the major factors determining performance of high power rf components and rf sources. RF breakdown limits working power and produces irreversible surface damage. The breakdown limit depends on the rf circuit, structure geometry, and rf frequency. It is also a function of the input power, pulse width, and surface electric and magnetic fields. In this paper we discuss multi...
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 کاملGradient Limitations for High-Frequency Accelerators
The main gradient limitation for high frequency accelerators is rf breakdown. While the physics of this gradient limitation still lacks a full theoretical understanding, a fairly complete empirical picture has emerged from the experimental work done in the past few years to characterize this phenomenon. Experimental results obtained mostly in the framework of the NLC/GLC project at 11 GHz and f...
متن کاملSummary Report of Working Group 3: Laser and High-Gradient Structure-Based Acceleration
Working Group (WG) 3 assessed current challenges in developing advanced accelerators based on RF and laser-driven electromagnetic (EM) structures and surveyed the state-of-the-art research and methods addressing these challenges. A critical challenge for EM structures is the gradient limitation imposed by RF breakdown, pulsed heating, dark current, quench, thermal breakdown and other factors, d...
متن کاملطراحی، ساخت و مقایسه دو ترکیب کننده توان با محفظه هممحور و استوانهای
Resonant structure is one of the proposed methods in combining power in RF systems of RF accelerators. In this structure, fabrication of RF power divider or combiner using coaxial and cylindrical cavity is important. In this study, two combiners, in the same frequency band, are designed and fabricated; and their results are compared. The experimental results confirmed the simulation results an...
