COMPASS Upgrade is a new medium size, high magnetic field tokamak (R= 0.9 m, B t= 5 T,
I p= 2 MA) currently under design in the Czech Republic. It will provide unique capabilities …

Abstract Theory-based scaling laws of the near and far scrape-off layer (SOL) widths are
analytically derived for L-mode diverted tokamak discharges by using a two-fluid model. The …

In magnetic confinement thermonuclear fusion the exhaust of heat and particles from the
core remains a major challenge. Heat and particles leaving the core are transported via …

The role of the COMPASS tokamak in research of generation, confinement and losses of
runaway electron (RE) population is presented. Recently, two major groups of experiments …

The first Indian tokamak, ADITYA, operated for over two decades with a circular poloidal
limiter, has been upgraded to a tokamak named ADITYA Upgrade (ADITYA-U) to attain …

COMPASS-U, a high magnetic field tokamak with hot walls, will be designed and built at IPP
Prague. Unique features of this new device bring noticeable constraints and requirements …

The reduction of the incident heat flux onto the divertor will be a necessity for the future
thermonuclear reactors. Impurity seeding is recognized as an efficient way to achieve the …

Abstract The COMPASS-U tokamak (R= 0.894 m, a= 0.27 m, B t= 5 T, I p= 2 MA) is a new
medium-size device with fully metallic plasma facing components, currently under …

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 …
