Short period high field undulators are required for compact Free Electron Lasers. Permanent magnet based hybrid undulators, well understood from a technological point of view, are still very competing when temperature is decreased, enabling both the coercivity and the remanence to be enhanced. At SOLEIL, the used PrFeB magnets enable to avoid the spin transition reorientation phenomenon...

REGAE is a small electron linear accelerator at DESY. In order to inject short and low charged electron bunches in to laser-driven plasma wakefield permanent magnetic solenoids for the final focus down to 10^-6 m were designed, assembled and field measurements were done.
Due to a shortage of space close to the operation area an in-vacuum solution has been chosen. Furthermore a two-ring...

An Coherent-electron Cooling (CeC) based on the FEL and micro-bunching instability had been proposed few years ago. Being a very flexible version of stochastic cooling, the CeC approach promises significant increase in the bandwidth and, therefore, significant shortening of cooling time in high-energy hadron colliders.In principle, it also can be considered as a possible final-stage cooling...

The next few years will see next-generation high-power laser facilities (such as the Extreme Light Infrastructure) become operational, for which it is important to understand how interaction with intense laser pulses affects the bulk properties of a relativistic electron beam. As we move to higher laser intensities, we expect both radiation reaction and quantum effects to play a significant...
