Detailed Description

Class used to implement Bremsstrahlung radiative cooling de/dt ~ -n^2 T^0.5 Specifically see Goldston & Rutherford (1995) Sec.

11.5 Eq. 11.57 This can be formulated as de/dt = -C Zeff Zbar^2 ni_tot^2 Te^1/2 where C = 2 pi^2 qe^6 / (sqrt(3)(4 pi eps0)^3 me^3/2 c^3 hbar * QE * n0 tau / sqrt(T0_J)) QE = Quantum effect correction = 0.75 hbar = reduced Planck constant = h / (2pi) Zeff = (sum_i Zi^2 ni) / (sum_i Zi ni) where i refers to all ion species Zbar = ne / ni_tot where i refers to all ion species and ni_tot = sum_i ni where i refers to all ion species ne = sum_i Zi ni by quasineutrality Te = Ti = T
