Measurements of the Plasma Current Density and Q-Profiles in IR-T1 Tokamak

Magnetic field simulations of the GOLEM tokamak via the NICE code

“…The profiles show dependencies on poloidal magnetic flux 𝜓 normalized on the poloidal magnetic flux at the last closed magnetic surface, i.e., plasma boundary 𝜓 edge . As GOLEM is a large aspect ratio (𝑅 0 /𝑎 0 ≈ 4.7), circular plasma cross-section tokamak, we were able to approximate the toroidal current density profile 𝑗 𝜙 (𝑟) as [15,23]…”

Approximate Methods for the Calculation of Plasma Internal Inductance for Circular Cross Section Tokamak

“…The internal inductance of the plasma per unit length normalized to 0 4π  is obtained from the conservation of zeroth order magnetic energy [3,4] as:…”

“…The second approximate value for the internal inductance can be easily obtained from the well-known Bennett current density profile [3,4], as:…”

“…In this work we present measurement of Plasma internal inductance (l i ) [3][4][5], which is essential in Tokamak plasma research. Much more plasma parameters such as the plasma current density profile, magnetohydrodynamics instability, and plasma energy confinement time can be determined by using this parameter.…”

“…In this paper we present theoretical calculation of Plasma internal inductance (l i ) for HT-7 Tokamak [1,2], (see Table 1). The Plasma internal inductance (l i ) is also studied for Tokamaks [3][4][5] by theoretical and experimental approach.…”
