FEL and optical klystron gain for an electron beam with oscillatory energy distribution∗
If the energy spread of a beam is larger then the Pierce parameter, the FEL gain length increases dramatically and the FEL output gets suppressed. We show that if the energy distribution of such a beam is made oscillatory on a small scale, the gain length can be considerably decreased. Such an oscillatory energy distribution is generated by first modulating the beam energy with a laser via the ...
متن کاملOptical-klystron Configuration for a High-gain X-ray Free Electron Laser
The amplified spontaneous-emission (ASE) regime of a free electron laser (FEL) can be used to produce coherent soft X-ray radiation in a long undulator (5 5 L -< 10 m) [1-6] . In such a regime, the initial incoherent radiation, with an optical power proportional to the number of electrons, is amplified by the electron beam itself as it traverses the interaction region subject to the combined pe...
متن کاملInvestigation of the Effect of Electron Beam Different Doses on Optical Dissipation in Fiber Optic
Measurement of ionizing radiation in various fields, such as environmental safety, industrial detection processes, radiation protection and medical is very important. Radiation dosimetry plays an important role in determining the amount of energy absorbed and the effects of radiation. Recent optical fiber sensors have been shown to be radiation dosimeters. Our goal here is to investigate the ef...
متن کاملA Source of Coherent Soft X-ray Radiation Based on High-order Harmonic Generation and Free Electron Lasers∗
We examine a scheme for a Free Electron Laser (FEL) harmonic amplifier seeded by a 30-nm wavelength signal produced using a process of High-order Harmonic Generation (HHG). The seed is first amplified in an optical klystron from 100 kW to 30 MW using a 1 GeV electron beam and then is used for an energy modulation of electrons in the downstream undulator. Subsequently, a 100MW level of radiation...
متن کاملSimulation of Laser - Electron Beam Interaction in the Optical Klystron of a Free Electron Laser
The particle optics code GPT [1] has been applied to study the single pass electron beam interaction with an external laser field in the undulator system of a free electron laser. In particular, this code has been used to simulate the laser electron beam interaction in an optical klystron. Micro-bunching as a result of the interaction of the electron bunch with an electromagnetic pulse is prese...
