Effect of magnetic barrier on the plasma parameters in a Trimix-M galatea

The parameters of plasma trapped in a Trimix-M galatea with increased values of the magnetic barrier and the energy of a hydrogen plasma bunch injected in the trap have been determined. For a barrier magnetic field of B _b ～ 0.1 T, the plasma confinement time in the trap is τ_p ≈ 300 μs (which agrees with estimates obtained using formulas describing the classical transfer), the maximum electron density is n _e ～ 5 × 10¹³ cm^?3, and the electron and ion temperatures are T _e ≈ 20 eV and T _i ～ 2T _e, respectively. The energy of trapped plasma is ～110 J, and the ratio of the gaskinetic to magnetic pressure in the plasma is β₀ ～ 0.2.
