چکیده
Abstract The Tokamak à Configuration Variable (TCV) tokamak is in the midst of an upgrade to further its capability investigate conventional and alternative divertor configurations. To that end, modular removable gas baffles have been installed decrease coupling between plasma core. primarily seek suppress transit recycling neutrals closed flux surfaces. A first experimental campaign with has shown baffled remains compatible a wide range configurations including snowflake super- X divertors. Plasma density ramp experiments reveal increase neutral pressure by up factor ×5 compared unbaffled thereby qualitatively confirm simulations SOLPS-ITER code were used guide baffle design. Together new upgraded diagnostics, TCV now validate models for ITER next step devices particular emphasis on geometric variations.

ELM induced divertor heat loads on TCV
Results are presented for heat loads at the TCV outer divertor target during ELMing H-mode using a fast IR camera. Benefitting from a recent surface cleaning of the entire first wall graphite armour, a comparison of the transient thermal response of freshly cleaned and untreated tile surfaces (coated with thick codeposited layers) has been performed. The latter routinely exhibit temperature tra...

The achievement of large volumetric power losses (dissipation) in the Alcator C-Mod divertor region is demonstrated in two operational modes: radiative divertor and detached divertor. During radiative divertor operation, the fraction of SOL power lost by radiation is P R/PSOL0.8 with single null plasmas, n e < 2x10 20 m-3 and I < 1 MA. These plasmas sometimes have very high recycling, with nedi...

متن کاملResiduated Skew Lattice with a Operation
In this paper, we define hedge operation on a residuated skew lattice and investigate some its properties. We get relationships between some special sets as dense, nilpotent, idempotent, regular elements sets and their hedges. By examples, we show that hedge of a dense element is not a dense and hedge of a regular element is not a regular. Also hedge of a nilpotent element is a nilpotent and h...
