Geodesic acoustic modes (GAMs) are ubiquitous oscillatory flow phenomena observed in
toroidal magnetic confinement fusion plasmas, such as tokamaks and stellarators. They are …

As a low-Z material, lithium is widely tested and used in tokamak devices for particle
recycling and impurity control to improve plasma performance. Lithium application as …

Tungsten (W) is one of the most promising plasma-facing materials for future fusion devices.
Although its melting point is the highest among all metals, it still has great risk of melting …

Since the first plasma realized in 2020, a series of key systems on HL-3 (known as HL-2M
before) tokamak have been equipped/upgraded, including in-vessel components (the first …

Geodesic acoustic modes, Alfvén eigenmodes, stationary and oscillating components of the
electric field, and their relations to plasma confinement have been studied. Theoretical …

The article begins with a brief review of the achievements of Russian tokamaks in the active
period of their development from 1962 to 1973, under the leadership of academician LA …

Local fluctuations of electrostatic potential, poloidal electric field, magnetic potential and
electron density are simultaneously measured in the T-10 tokamak by a heavy ion beam …

The PLM plasma device was constructed for high heat flux tests of fusion plasma-facing
materials and in-vessel components of a fusion reactor. The ITER-grade tungsten samples …

The paper is focused on the new systematic measurements of the 3D spatial distributions of
the amplitudes, the radial correlation lengths and the long-range correlations along the …

Gradual or abrupt transitions from a coherent mode to quasi-coherent mode (QCM, a type of
trapped electron mode turbulence) are observed in the core region of low-density plasmas …
