Coherent Synchrotron Radiation and Stability of a Short Bunch in a Compact Storage Ring
نویسندگان
چکیده
It should be possible to observe coherent synchrotron radiation at millimeter wavelengths in a compact electron storage ring, provided that the bunch can be made su ciently short. On the other hand, for a short bunch the radiation reaction is so strong that it could cause a longitudinal instability if the current exceeded some threshold. This might cause bunch lengthening, and cut o or reduce the coherent radiation. Using wake elds from simple models of the vacuum chamber, we estimate the threshold current for a proposed upgrade of the Brookhaven small x-ray light source, SXLS Phase I.

Millimeter Wave Coherent Synchrotron Radiation in a Compact Electron Storage Ring
Installation of a 2856 MHz RF system into the XLS compact electron storage ring would allow the generation of millimeter wave coherent synchrotron radiation. Operating at 150 MeV, one could produce bunches containing on the order of 2x107 electrons with a bunch length σ L0 = 0.3 mm, resulting in coherent emission at wavelengths above 0.8 mm. The characteristics of the source and the emitted rad...

Strong evidence for self-excited emission of coherent synchrotron radiation in the microwave spectral region was observed at the Synchrotron Ultraviolet Radiation Facility (SURF III) electron storage ring at the NIST. The microwave emission between 25 and 35 mm was dominated by intense bursts of radiation. The intensity enhancement during these bursts was on the order of 10 000 to 50 000 over t...
متن کاملBursts of coherent synchrotron radiation in electron storage rings: a dynamical model.
Evidence of coherent synchrotron radiation has been reported recently at the electron storage rings of several light source facilities. The main features of the observations are (i) a radiation wavelength short compared to the nominal bunch length, and (ii) a coherent signal showing recurrent bursts of duration much shorter than the radiation damping time, but with spacing equal to a substantia...

متن کاملA Model for Producing Stable, Broadband Terahertz Coherent Synchrotron Radiation in Storage Rings*
We present a model for producing stable broadband coherent synchrotron radiation (CSR) in the terahertz frequency region in an electron storage ring. The model includes distortion of bunch shape from the synchrotron radiation (SR), enhancing higher frequency coherent emission and limits to stable emission due to a microbunching instability excited by the SR. We use this model to optimize the pe...
