Radiation of Runaway Electrons in Tokamaks

  • Department: Department of Physics
  • Annotation:
    Electrons, as relatively light particles, are easy to manipulate. Even a weak electric or magnetic field will cause them to move. In plasma, electrons are in the so-called ohmic mode under normal situations. Acceleration by an electric field is compensated by electron collisions with the surrounding plasma. At high velocities, the effective cross section of the interaction of the electron with the environment decreases and it may happen that the collision processes can no longer compensate for the acceleration by the electric field. The electron enters a passing mode, where it is accelerated by an electric field so that it acquires a relativistic velocity and considerable energy, which can exceed the rest energy at rest several times over. In this paper we deal with the radiation of passing electrons and the threshold energy at which the radiation reaction of this radiation takes over the role of the braking force caused by collisions.

Runaway electron experiments at COMPASS in support of the EUROfusion ITER physics research

    The role of the COMPASS tokamak in research of generation, confinement and losses of runaway electron (RE) population is presented. Recently, two major groups of experiments aimed at improved understanding and control of the REs have been pursued. First, the effects of the massive gas injection (\sim 10^21$ Ar/Ne particles) and impurity seeding (\sim 10^18$ particles) were studied systematically. The observed phenomena include generation of the post-disruption RE beam and current conversion from plasma to RE. Zero loop voltage control was implemented in order to study the decay in simplified conditions. A distinctive drop of background plasma temperature and electron density was observed following an additional deuterium injection into the RE beam. With the loop voltage control the parametric dependence of the current decay rate d I /d t can be studied systematically and possibly extrapolated to larger facilities. Second, recent results of experiments focused on the role of the magnetic field in physics of RE were analysed. In this contribution, special attention is given to the observed effects of the resonant magnetic perturbation on the RE population. The benefits of the RE experiments on COMPASS was reinforced by diagnostic enhancements (fast cameras, Cherenkov detector, vertical ECE etc) and modelling efforts (in particular, coupling of the METIS and LUKE codes).

First Measurement of X-rays Generated by Runaway Electrons in Tokamaks Using a TimePix3 Device with 1 mm thick Silicon Sensor

  • Annotation:
    An application study of modern pixel semiconductor detectors for characterization of runaway electron events in tokamaks is presented. Characterization techniques utilizing both spectroscopic measurements and monitoring of the intensity of secondary X-rays produced by the runaway electrons were used. Energy spectra of X-rays and time evolutions of their intensity on two tokamaks (Golem and Compass) were measured under different conditions and compared with results of standard runaway diagnostics. The energy spectra measured on both tokamaks have similar exponential shapes but with a significant variation in numbers of events per shot. The time evolutions of the X-ray intensity during several discharges on the tokamak Golem were measured using both the Timepix3 device and scintillation detectors (NaI:Tl and YAP:Ce). On a microsecond time scales, the signal time evolution measured by the TimePix3 device shows patterns in a form of unexpected or periodic-like increases of the intensity. We have also observed significant differences in number of events of the detected X-rays generated by the runaway electrons flying frontward and backward with respect to a limiter of the tokamak Golem. This fact declares that the runaway electrons have relativistic velocities. The experiments on the tokamak Compass provide similar results. Measurements in the immediate vicinity of tokamak Compass were impossible to perform because of a rapid change of the tokamak magnetic field. Measurements performed in the distance of at least 0.5 m from a diagnostic port of the tokamak Compass gave millions of correctly measured events per shot and an unknown number of events affected by pileups. The correctly measured events were used for construction of energy spectra and the time evolutions of the X-ray intensity.

Notes on the relativistic movement of runaway electrons in parallel electric and magnetic fields

  • DOI: 10.1063/1.4962687
  • Link: https://doi.org/10.1063/1.4962687
  • Department: Department of Physics
  • Annotation:
    Runaway electrons are a potential threat in many plasma devices. At high velocities, the plasma acceleration is not further offset by collisions in the plasma, as in the ohmic regime. The particles obtain relativistic velocity and considerable energy. A typical configuration includes parallel electric and magnetic fields, in which there are no drifts, and the movement of the charged particles is a combination of gyration motion with the acceleration in an electric field. It follows from the Lorentz equation of motion that the transverse velocity component (perpendicular to the fields) will be interconnected with the longitudinal component via the Lorentz factor. The increasing longitudinal velocity will therefore ultimately reduce the magnitude of the transverse velocity component, thereby decreasing the gyrofrequency. The corresponding change in Larmor radius will be offset by the increase in the particle mass and the Larmor radius of gyration therefore remains unchanged. We derive analytical relations for the temporal and spatial dependences of frequency, and longitudinal and transverse components of the velocity.

    Cosmic microwave background exists all around us. It is the light from the end of the Big Bang, which carries valuable information about the early universe and the environment, through which it passed. Most of the information about distant objects we obtain through electromagnetic radiation of various wavelengths. In the microwave band today's specialized probes watch not only the coldest corners of the universe, but also the light of ancient times, which started its journey in the period when electron shells of the atoms formed in the universe.

Runaway electrons behaviour

  • Department: Department of Physics
  • Annotation:
    Runaway electron behaviour have been investigated both analytically and numerically. The electron energy growth equation was derived, and critical energies calculated analytically. In numerical simulations, the initial Maxwell distribution was deformed in a typical manner. The runaway electrons were accelerated in the presence of longitudinal magnetic field (parallel to the electric one), which in non-relativistic case does not influence the motion of the electrons along the electric field lines. Our simulations show, that this is not true in the relativistic case.

Analysis of the Instability Growth Rate During the Jet - Background Interaction in the Magnetic Field

  • DOI: 10.1088/1674-4527/13/6/008
  • Link: https://doi.org/10.1088/1674-4527/13/6/008
  • Department: Department of Physics
  • Annotation:
    The two-stream instability is the common instability, which is responsible for many observed phenomena in nature, especially the interaction of the jets of various origin with the background plasma (e.g. extragalactic jet penetrating into the cosmic background). The dispersion relation without magnetic field is described by the well-known Buneman relation, but in 2011 Bohata, Bren, and Kulhanek derived the relation for the two-stream instability without the cold limit and with the general orientation of magnetic field. The maximum value of the imaginary part of the individual dispersion branches is very interesting from the physical point of view. It represents the instability growth rate which is responsible for the turbulence mode onset and subsequent reconnection on the ion radius scale accompanied by strong plasma thermalization. The paper presented here is focused on the instability growth rate dependence on various input parameters, such as magnitude and direction of magnetic field, sound velocity, plasma frequency of the jet and direction of the wave vector during the jet -- background interaction. The results are presented in well-arranged plots and can be used for lookup of the plasma parameters close to which the strong energy transfer and thermalization between the jet and the background plasma occurs.
