The performance of future linear colliders will depend critically on beam-based alignment and feedback systems. In ILC and CLIC it is planned to perform dispersion-free steering in the main linacs. To this end the beams are accelerated with different

The linac coherent light source (LCLS) is a self-amplified spontaneous emission (SASE) free-electron laser (FEL) operating at fundamental photon energies from 0.5 to 10 keV. Characterization of the higher harmonics present in the FEL beam is importan

The scaling of the two important figures of merit, the transformer ratio T and the longitudinal electric field E_{z}, with the peak drive-bunch current I_{p}, in a nonlinear plasma wakefield accelerator is presented for the first time. The longitudin

Multi-GeV trapped electron bunches in a plasma wakefield accelerator (PWFA) are observed with normalized transverse emittance divided by peak current, ϵ_{N,x}/I_{t}, below the level of 0.2 μm/kA. A theoretical model of the trapped electron emittanc

The concept of using short plasma sections several meters in length to double the energy of a linear collider just before the collision point is proposed and modeled. In this scenario the beams from each side of a linear collider are split into pairs

In a recent Brief Comment, the results of an experiment to measure the refraction of a particle beam were reported [P. Muggli et al., Nature 411, 43 (2001)]. The refraction takes place at a passive interface between a plasma and a gas. Here the full

Magnetic skyrmions are topological spin textures that exhibit classical or quantum quasiparticle behavior. A substantial amount of research has occurred in this field, both because of their unique electromagnetic properties and potential application

The development of new modes at x-ray free electron lasers has inspired novel methods for studying fluctuations at different energies and timescales. For closely spaced x-ray pulses that can be varied on ultrafast time scales, we have constructed a p

We present design and characteristics of a population inversion X-ray laser oscillator (XLO) at LCLS. We report on first experiments and future plans towards XLO demonstration. We also discuss necessary upgrades to LCLS for optimized XLO performance.
