Plasma Physics
K (Gas Temperature ~300 K)
A non-thermal plasma discharge generated at ambient atmospheric pressure where heavy ions remain near room temperature while free electrons reach high temperatures.
T_gas ≈ 300 K (Room Temp), T_electron ~ 10,000–50,000 K
Coulomb Logarithm
Plasma Physics
Dimensionless Parameter (ln Λ)
The natural logarithm of the ratio of maximum to minimum impact parameters in small-angle Coulomb collision integrals.
ln Λ = ln(r_max / r_min) = ln(λ_D / b_min) ≈ 10–20
Cyclotron & Synchrotron Emission
Plasma Physics
W (Radiated Power)
Electromagnetic radiation emitted by charged particles undergoing gyromotion acceleration around magnetic field lines in a plasma.
P_rad = (2 e⁴ B² v_⊥²) / (3 m_e² c³) (Non-relativistic Cyclotron)
