Advanced operation modes relying on core plasma turbulence stabilization in tokamak fusion devices
AAPPS Bulletin, 2023 Recent progress of advanced operation modes in tokamaks is addressed focusing upon internal transport barrier (ITB) discharges. These ITB discharges are being considered as one of candidate operation modes in fusion reactors.

Hadroproduction of neutral Kstar-mesons up to LHC energies [PDF]
, 2018 We consider the experimental data on neutral Kstar-meson production on nucleon and nuclear targets. The Quark-Gluon String Model quantitatively describes the inclusive density in the midrapidity region, as well as the initial energy and A dependences of ...

Shutdown Dose Rate Analysis for the long-pulse D-D Operation Phase in KSTAR
EPJ Web of Conferences, 2017 KSTAR is a medium size fully superconducting tokamak. The deuterium-deuterium (D-D) reaction in the KSTAR tokamak generates neutrons with a peak yield of 3.5x1016 per second through a pulse operation of 100 seconds.

Interpretation of suprathermal emission at deuteron cyclotron harmonics from deuterium plasmas heated by neutral beam injection in the KSTAR tokamak [PDF]
, 2019 Intense bursts of suprathermal radiation, with spectral peaks at frequencies corresponding to the deuteron cyclotron frequency in the outer midplane edge region, are often detected from deuterium plasmas in the KSTAR tokamak ...

Inter-ELM heat loads on tungsten leading edge in the KSTAR divertor
Nuclear Materials and Energy, 2017 A series of leading edge heat load experiments are performed in KSTAR to study power balance and to support a divertor shaping decision on ITER. Tungsten blocks with leading edges of various heights were fabricated, adjusted and mounted to central ...

Sub-microsecond temporal evolution of edge density during edge localized modes in KSTAR tokamak plasmas inferred from ion cyclotron emission [PDF]
, 2019 During edge localised mode (ELM) crashes in KSTAR deuterium plasmas, bursts of spectrally structured ion cyclotron emission (ICE) are detected. Usually the ICE spectrum chirps downwards during an ELM crash, on sub-microsecond timescales.
