bapsflib.plasma.core.cs(kTe, m_i, Z, gamma=1.0, **kwargs)

ion sound speed (cm/s)

\[C_{s} = \sqrt{frac{\gamma Z k T_{e}}{m_{i}}}\]

Note

\(\gamma=1\) for the case of \(T_{i}\ll T_{e}\) (DEFAULT)

Parameters:

• kTe (float) – electron temperature (in eV)

• m_i (float) – ion mass (in g)

• Z (int) – charge number

• gamma (float) – adiabatic index
