Research Abstract

This research project has been carried out to study relativistic runaway electron beams and high-current relativistic plasmas created in tokamak devices. Major results are shown below.
1. Diagnostics of Runaway Electron Beams based on Laser Inverse Compton Scattering (LCS)
(1) Basic properties of energy spectrum of LCS photons, photon number, and scattering directions for plasma parameters of relativistic runaway electron beams in JT-60U tokamak have been evaluated.
(2) Basic properties of background radiations, e.g. relativistic bremsstralung radiation, relativistic synchrotron radiation, inverse Compton scattering, have been evaluated.
(3) A YAG laser, a laser transmission fiber cable, a vacuum window, a detector, and data acquisitions have been installed in JT-60U tokamak.
2. Study of High-Current Relativistic Plasmas
(1) Disruption generated runaway plasmas observed in JT-60U tokamak have been investigated. It has been shown that runaway electrons can be exhausted by impurity pellet injection. It has been suggested that the temporal behavior of runaway electron current can be explained by the balance of avalanche generation of runaway electrons and their decay with synchrotron radiation.
(2) It has been shown that current quench disruption is avoided by the combination of electron cyclotron wave heating and generation of runaway electrons.
