Further upgrades of the ASDEX Upgrade ICRF system [PDF]

EPJ Web of Conferences
The original plans were to operate the tokamak ASDEX Upgrade (AUG) for ten years. The flexibility of the experiment lead to the fact, that AUG is now operating for over three decades.

Novel concept suppressing plasma heat pulses in a tokamak by fast divertor sweeping

Scientific Reports, 2022
One of the remaining challenges in magnetic thermonuclear fusion is survival of the heat shield protecting the tokamak reactor vessel against excessive plasma heat fluxes.

Laminar shocks in high power laser plasma interactions [PDF]

, 2013
We propose a theory to describe laminar ion sound structures in a collisionless plasma. Reflection of a small fraction of the upstream ions converts the well known ion acoustic soliton into a structure with a steep potential gradient upstream and with ...

ECRH scenarios with selective heating of trapped/passing electrons in the W7-X Stellarator

EPJ Web of Conferences, 2015
Using specific features of the magnetic equilibrium in the W7-X stellarator, the ECRH scenarios with combined X2 and X3 modes are discussed. The RF beams for operation with X2 and X3 modes need to be launched from low- and, via the remote steering ...

Tracing solar wind plasma entry into the magnetosphere using ion-to-electron temperature ratio [PDF]

, 2009
When the solar wind Mach number is low, typically such as in magnetic clouds, the physics of the bow shock leads to a downstream ion-to-electron temperature ratio that can be notably lower than usual.
