Plasma Physics
s (Energy Confinement Time τ_E)
High-confinement operating regime in tokamaks characterized by a steep edge pressure barrier (pedestal) and doubled energy confinement time.
Energy Confinement Time τ_E(H-mode) ≈ 2 × τ_E(L-mode)
Hall Effect Thruster
Plasma Physics
N or mN (Thrust) & s (Specific Impulse ~1500–3000 s)
A electric space propulsion plasma engine that accelerates ions across an electrostatic potential drop using trapped electrons in an annular magnetic field.
F_thrust = ṁ v_exhaust, v_ex = √(2 e V_acc / m_ion)
