Psep/PLH control in deuterium and deuterium-tritium JET plasmas

The high confinement mode (H-mode) is a promising route to achieve high performance tokamak operations, as the ones foreseen in ITER and beyond. However, accessing a stable H-mode phase requires that the power across the plasma separatrix, Psep, exceeds a ...

Sawtooth crash in tokamak as a sequence of multi-region relaxed MHD equilibria

Joaquim Loizu Cisquella

This study examines the sawtooth crash phenomenon in tokamak plasmas by modeling it as a sequence of multi-region relaxed magnetohydrodynamic (MRxMHD) equilibria. Using the stepped-pressure equilibrium code, we constructed a series of equilibria representi ...

Experiments and SOLEDGE3X modeling of dissipative divertor and X-point Radiator regimes in WEST

Holger Reimerdes

X-Point Radiator (XPR) regimes have been obtained in WEST tokamak experiments with nitrogen seeding during the experimental campaigns of 2023 and 2024. These experiments showed the formation of a stable toroidal radiating ring near the X-point, similar to ...

Analysis techniques for blob properties from gas puff imaging data

Christian Gabriel Theiler, Curdin Tobias Wüthrich, Guillaume Raphäel Hervé Van Parys, Nicola Offeddu

Filamentary structures, also known as blobs, are a prominent feature of turbulence and transport at the edge of magnetically confined plasmas. They cause cross-field particle and energy transport and are, therefore, of interest in tokamak physics and, more ...

Enhanced performance in fusion plasmas through turbulence suppression by megaelectronvolt ions

Samuele Mazzi

Alpha particles with energies on the order of megaelectronvolts will be the main source of plasma heating in future magnetic confinement fusion reactors. Instead of heating fuel ions, most of the energy of alpha particles is transferred to electrons in the ...

Periodogram-Based Detection of Unknown Frequencies in Time-Resolved Scanning Transmission X-ray Microscopy

Joe Martin Bailey

Pump-probe time-resolved imaging is a powerful technique that enables the investigation of dynamical processes. Signal-to-noise and sampling rate restrictions normally require that cycles of an excitation are repeated many times with the final signal recon ...

Divertor closure effects on the TCV boundary plasma

Basil Duval, Holger Reimerdes, Benoît Labit, Sri Harsha Kasi Raj, Christian Gabriel Theiler, Umar Sheikh, Lorenzo Martinelli, Claudia Colandrea

The Tokamak a Configuration Variable (TCV) has recently been equipped with gas baffles to increase its divertor closure for a broad range of divertor magnetic geometries. First experimental results reported in Reimerdes et al. (2021) demonstrated compatibi ...

Selection of the silicon sensor thickness for the Phase-2 upgrade of the CMS Outer Tracker

Simone Scarfì

During the operation of the CMS experiment at the High-Luminosity LHC the silicon sensors of the Phase-2 Outer Tracker will be exposed to radiation levels that could potentially deteriorate their performance. Previous studies had determined that planar flo ...
