4. INVESTIGATING PRIMARY RUNAWAY ELECTRON GENERATION MECHANISMS WITH TEST PARTICLES IN NON-LINEAR MHD DISRUPTION SIMULATIONS

Mr Cristian Sommariva (CEA-Cadaracher/IRFM)

6/8/17, 9:15 AM

Oral

During a tokamak disruption, a large electric field is formed which can lead to the generation of a runaway electron (RE) beam. In large machines, runaway beams are sufficiently intense and energetic to represent a serious threat for operations. Therefore, the comprehension of the physics of RE and of their mitigation is of fundamental importance for future operations. Up to now, most RE...

21. Runaway electrons and JT-60SA

Mr Konsta Sarkimaki (Aalto University)

6/8/17, 9:55 AM

Oral

5. Improved fluid models of runaway generation and decay

Mr Ola Embréus (Chalmers University of Technology)

6/8/17, 10:50 AM

Oral

Full kinetic modeling of runaway dynamics is remarkably expensive computationally due to the range in scales involved, requiring simultaneous resolution of both the near-isotropic thermal electron population in the eV energy scale, as well as the strongly anisotropic runaways in the tens-of-MeV range. Because of this, a fluid description of runaway dynamics is highly desirable, where runaway...

22. Overview of 2016 TCV experiments

Joan Decker

6/8/17, 11:30 AM

19. Overview of ITER Hard X-Ray Monitor

Mr Santosh Pandya (Institute for Plasma Research)

6/8/17, 1:30 PM

Oral

There are very few methods that have the capability to provide energy-resolved measurements of Runaway Electrons. Hard X-Ray Monitor (HXRM) allows an estimation of the maximum runaway electron energy and the energy distribution function inferred from energy-resolved measurements. Implementation of HXRM system has been relatively easy on other worldwide Tokamaks. However, at ITER this will be...

20. Summary of 5th REM 2017

Jan Mlynář

6/8/17, 2:00 PM

Oral

In this concluding summary presentation the main results from the meeting will be collected. This should allow the participants to remind and put into context some of the highlights of the REM 2017. Contributors to the REM are welcome to propose one slide and a few concluding remarks into this presentation and, in particular, to think over suitable conclusions, comments and questions for the...
