Runaway electron energy measurement using hard x-ray spectroscopy in "Damavand" tokamak.

Set of experiments has been developed to study existing runaway electrons in "Damavand" tokamak plasma upon characteristics of hard x-ray emissions produced by collision of the runaway electrons with the plasma particles and limiters. As a first step, spatial distribution of hard x-ray emissions on the equatorial plane of the torus was considered. Obtained spectra of hard x-ray emissions for di...

Suprathermal electron studies in the TCV tokamak: design of a tomographic hard-x-ray spectrometer.

Electron cyclotron resonance heating and electron cyclotron current drive, disruptive events, and sawtooth activity are all known to produce suprathermal electrons in fusion devices, motivating increasingly detailed studies of the generation and dynamics of this suprathermal population. Measurements have been performed in the past years in the tokamak a configuration variable (TCV) tokamak usin...

Attosecond Hard X-Ray Scattering Spectroscopy

Synopsis We formulate an analytic, semi-relativistic theory of laser-assisted attosecond Compton scattering by a weakly bound electron. We (i) present the evidence of the feasibility of measuring the ground-state electron momentum density in the attosecond regime and (ii) investigate the attosecond Compton streak camera and spectral phase interferometry proposing two new methods of measuring th...

Energy-dispersive X-ray emission spectroscopy using an X-ray free-electron laser in a shot-by-shot mode.

The ultrabright femtosecond X-ray pulses provided by X-ray free-electron lasers open capabilities for studying the structure and dynamics of a wide variety of systems beyond what is possible with synchrotron sources. Recently, this "probe-before-destroy" approach has been demonstrated for atomic structure determination by serial X-ray diffraction of microcrystals. There has been the question wh...

Criteria for Runaway Electron Generation in Tokamak Disruptions

Experimental observations show that there is a magnetic field threshold for runaway electron generation in tokamak disruptions. A possible explanation for these observations is that the runaway beam excites whistler waves that scatter the electrons in velocity space and prevents the beam from growing. The growth rates of the most unstable whistler waves are inversely proportional to the magneti...
