Velocity Bunching Experiments at Sparc
نویسنده
چکیده
During the last SPARC run a preliminary experimental study of the velocity bunching technique has been performed. Bunch length and projected emittance have been measured at the linac exit as a function of the injection phase in the first accelerating structure and for different solenoids field values. A maximum compression ratio up to a factor 13 has been observed. In particular a peak current of 120 A with 300 pC in a 2.3 ps FWHM long bunch with emittance lower than 2 mm-mrad has been measured with a compression factor 3. In this paper we describe the results achieved so far and a comparison with simulations is also reported.

Compression of an Electron-bunch by Means of Velocity Bunching at ARES
ARES is a planned linear accelerator for research and development in the field of production of ultra-short electron bunches. The goal of ARES is to produce low charge (0.2 50 pC), ultra-short (from few fs to sub-fs) bunches, with improved arrival time stability (less than 10 fs) for various applications, such as external injection for Laser Plasma Wake-Field acceleration. The ARES layout will ...

The SPARC project foresees the realization of a high brightness photo-injector to produce a 150200 MeV electron beam to drive 500 nm FEL experiments in various configurations, a Thomson backscattering source and a plasma accelerator experiment (these last two ones jointly with the project PLASMONX). The SPARC photoinjector is also the test facility for the recently approved VUV FEL project name...
متن کاملSimultaneous bunching and debunching of surface steps: Theory and relation to experiments.
We study a model of two-dimensional step flow where the velocity of a step depends predominantly on the width of the terrace remaining behind it. While the uniform step train is unstable towards step bunching, the bunches themselves are unstable and tend to debunch. This leads to patterns where slow moving fairly straight bunches coexist with fast, strongly bent single steps, in qualitative agr...
متن کاملبررسی و تحلیل عوامل مؤثر بر دینامیک باریکه الکترون در خوشهساز شتابدهنده خطی الکترون
In this paper, the importance of the buncher in linear electron accelerators is discussed and two types of bunchers, velocity-modulation and disk-loaded, are introduced. Higher bunching factor, larger initial phase range, and smaller final phase range are favorable in the disk-loaded buncher. Our investigations showed that the aforementioned situations can be met by appropriate changes in the ...
متن کاملMicrobunching instability in velocity bunching∗
Microbunching instability is one of the most challenging threats to FEL performances. The most effective ways to cure the microbunching instability include suppression of the density modulation sources and suppression of the amplification process. In this paper we study the microbunching instability in velocity bunching. Our simulations show that the initial current and energy modulations are s...
