- Title: Does synchrotron emission really limit the runaway energy ? AND What should we expect at 8 tesla?
- Abstract: Using RE synchrotron spectra from Alcator C-Mod, we are trying to determine whether or not the radiated power from RE synchrotron emission is actually limiting the maximum energy of the RE distribution, as suggested by some theories. As shown in Alex Tinguely's presentation, we fit the observed SR spectra to the spectra calculated from both a mono-energetic distribution and a continuum distribution. So far, we are not able to distinguish between the two different types of distributions based just on the spectral fits, at least not for B = 5.4 T that we've run so far. But we are also studying the evolution of the spectra during a discharge, and comparing spectra from different discharges, to determine if this can shed more light on this issue. These additional observations may support the conjecture that synchrotron emission is limiting the maximum RE energy. We continue to work with the theory community to better understand this validity of this assertion.

17) Lehnen Michael (ITER Organization, France) attends the REM meeting.
- Title: Research needs for runaway avoidance and mitigation in ITER
- Abstract: Runaway electrons remain the major challenge for ITER disruption mitigation. Two layers of defense are presently foreseen to prevent runaway impact on the first wall: avoidance and mitigation. Avoidance is part of the thermal and electro-magnetic load mitigation. Although confidence is gained from JET experiments and from initial modelling that a disruption mitigation scheme can be found that avoids runaway formation, further extensive R&D is required to extrapolate to ITER. The present runaway mitigation concept is based on energy dissipation through high-Z injection. This scheme is not yet confirmed for ITER. Experiments and modelling efforts have clearly increased in the past years to tackle this issue. Nevertheless, further R&D will be needed to address the fuelling efficiency of the injection into a runaway beam and to confirm the impurity densities required for sufficiently fast energy dissipation, taking into account equilibrium evolution and MHD stability.

18) Liu Chang (Princeton University, USA) attends the REM meeting.
- Title: Cherenkov radiation of runaway electrons
- Abstract: Runaway electrons are very important area of current research in tokamak disruptions. In this talk we present our recent theoretical study of the Cherenkov radiation from runaway electrons in plasmas. The radiation loss of Cherenkov radiation gives a correction to the Coulomb logarithm in the collisional drag force. In magnetized plasmas, Cherenkov radiation will be enhanced by the B field. In addition, Transit Time Magnetic Pumping (TTMP) from the emitted waves can cause parallel momentum loss of runaway electrons. These effects will change the runaway electron avalanche threshold and the growth rate.
