Laser seeding of the storage-ring microbunching instability for high-power coherent terahertz radiation.
We report the first observation of laser seeding of the storage-ring microbunching instability. Above a threshold bunch current, the interaction of the beam and its radiation results in a coherent instability, observed as a series of stochastic bursts of coherent synchrotron radiation (CSR) at terahertz frequencies initiated by fluctuations in the beam density. We have observed that this effect...
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...
متن کاملInvestigation of Microbunching-instability in Berlinpro
The Helmholtz Zentrum Berlin (HZB) is building an energy recovery linac (ERL) prototype, bERLinPro, to demonstrate the ERL principle at low emittance and high currents. As, maintaining the low emittance and energy spread is crucial for generation of high brightness synchrotron radiation, the deep understanding and control of effects degrading the emittance and energy spread are of major interes...
متن کاملBeam Instability and Microbunching due to Coherent Synchrotron Radiation
A relativistic electron beam moving in a circular orbit in free space can radiate coherently if the wavelength of the synchrotron radiation exceeds the length of the bunch. In accelerators coherent radiation of the bunch is usually suppressed by the screening effect of the conducting walls of the vacuum chamber [1, 2]. The screening effect is weak for short wavelengths, but if the wavelength is...
متن کاملTheory and Observations of Microbunching Instability in Electron Machines∗
For not very short bunches, the coherent synchrotron radiation (CSR) is usually suppressed by the shielding effect of the conducting walls of the vacuum chamber. However an initial density fluctuation in the beam with a characteristic length much shorter than the bunch length can radiate coherently. If the radiationreaction force drives growth of the initial fluctuation, one can expect an insta...
