Optical klystron FEL scheme for x-ray coherent harmonic generation at ISLF storage ring
The possibility of inserting an optical klystron on the storage ring of an Iranian Light Source Facility as a Synchrotron Radiation Free electron Laser for coherence harmonic generation in the soft x-ray spectrum has been studied. The study has been performed using the 3D FEL simulation code GENESIS 1.3 and in accordance with the available characteristic parameters of ISLF. Different potential ...
متن کاملStudy of Bunch Instabilities by the Nonlinear Vlasov-Fokker-Planck Equation
Instabilities of the bunch form in storage rings may be induced through the wake field arising from corrugations in the vacuum chamber, or from the wake and precursor fields due to coherent synchrotron radiation (CSR). For over forty years the linearized Vlasov equation has been applied to calculate the threshold in current for an instability, and the initial growth rate. Increasing interest in...
متن کاملA model describing stable coherent synchrotron radiation in storage rings.
We present a model describing high power 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), which enhances higher frequency coherent emission, and limits to stable emission due to an instability excited by the SR wakefield. It gives a quantitative e...
متن کاملCollective effects in a diffraction-limited storage ring.
This paper gives an overview of collective effects that are likely to appear and possibly limit the performance in a diffraction-limited storage ring (DLSR) that stores a high-intensity ultra-low-emittance beam. Beam instabilities and other intensity-dependent effects that may significantly impact the machine performance are covered. The latter include beam-induced machine heating, Touschek sca...
متن کاملLimitation of Beam Current in the Pls Storage Ring
We present investigations on beam instabilities that have been observed at 2.0 GeV and 2.5 GeV in the PLS storage ring. Stored beam currents of 2.0 GeV in the ring has been mainly limited by coupled-bunch instabilities. We have investigated dependences of the coupled-bunch instabilities on betatron tune, chromaticity and rf cavity temperatures at 2.0 GeV. 450 mA beam could be stored at 2.0 GeV....
