Alfvén eigenmode studies on JET

Valentin Aslanyan


Experiments to probe AEs with a resonant magnetic field have been undertaken on JET for 20 years. An upgrade to the AE active diagnostic (AEAD) antennas has recently been completed with the aim of measuring the modes' damping rates in upcoming DT experiments. The frequency range of the diagnostic has been extended downwards allowing detection of Beta (Acoustic) AEs and Geodesic Acoustic Modes, whose understanding is increasingly seen as important to future machines.

Taming the plasma-material interface in plasma-burning nuclear fusion reactors

Jean Paul Allain

University of Illinois at Urbana-Champaign

This talk will focus on outlining both the challenges and promises of PMI research in nuclear fusion today and the prospects for possible solutions for future plasma-burning fusion reactors.  The talk will in part summarize the recent DOE Fusion Energy Sciences Workshop on Plasma-Material Interactions and also highlight some of the recent work in Prof. Allain’s RSSEL group at UIUC.

The impact of divertor conditions on SOL density profile at the JET tokamak

Bruce Lipschultz

York University

The low temperature boundary layer plasma (Scrape-Off-Layer or SOL) between the hot core and the surrounding vessel determines the level of power loading and erosion and implantation of material surfaces, and thus the viability of tokamak-based fusion as an energy source. This study using the JET tokamak explores several mechanisms affecting the formation of flattened density profiles, the so-called density shoulders, in the low-field side (LFS) SOL.
