This review is devoted to tokamak plasmas with a cross sectional shape featuring negative
triangularity, which appear to hold great promise as a candidate reactor configuration owing …

Tokamaks have demonstrated excellent plasma confinement capability because of their
symmetry but has an intrinsic drawback because of their pulsed inductive operation. Efforts …

Plasma discharges with a negative triangularity (δ=-0.4) shape have been created in the DIII-
D tokamak with a significant normalized beta (β N= 2.7) and confinement characteristic of …

Infinite toroidal mode number (n=∞) ballooning mode analysis of negative triangularity
discharges on DIII–D shows that the access to 2 nd stability becomes strongly restricted …

Diverted discharges at negative triangularity on the DIII-D tokamak sustain normalized
confinement and pressure levels typical of standard H-mode scenarios (H 98y2≃ 1, β N≃ 3) …

Plasmas with a negative triangularity shape have been created on the DIII-D tokamak that,
despite maintaining standard L-mode edge radial profiles, reach volume averaged pressure …

The favorable confinement properties of negative-triangularity (NT) tokamak configurations
were discovered in the TCV tokamak in the late 1990s and were documented over the two …

The paper discusses edge stability, beta limits and power handling issues for negative
triangularity tokamaks. The edge magnetohydrodynamic stability is the most crucial item for …

The effects of plasma shaping, in particular triangularity (δ), on temperature fluctuations in
the tokamak à configuration variable have been studied using the correlation electron …

Global gradient driven gyrokinetic simulations performed with the Gyrokinetic
Electromagnetic Numerical Experiment (GENE) code are used to investigate Tokamak à …
