slactrac.PWFA.Plasma¶

class slactrac.PWFA.Plasma(n_p=None, n_p_cgs=None, species=<MagicMock name='mock.hydrogen' id='140000940722552'>)[source]¶

A class for relating plasma density to plasma frequency $\omega_p$ and ion focusing force.

Input plasma density either n_p in SI units, or n_p_cgs in CGS units.

Parameters:

Parameters:	n_p : float Plasma density in SI units. n_p_cgs : float Plasma density in CGS units. species : periodictable.core.Element The species of gas used (see `periodictable.core.Element`).

n_p : float

Plasma density in SI units.

n_p_cgs : float

Plasma density in CGS units.

species : periodictable.core.Element

The species of gas used (see periodictable.core.Element).

Attributes

`E_rest`	Rest energy of the plasma ion.
`m`	Mass of the ion in AMU.
`n_p`	Plasma density in SI units.
`n_p_cgs`	Plasma density in CGS units
`species`	Species used in plasma.
`w_p`	Plasma frequency $\omega_p$ for given plasma density

Methods

`beta_matched`(E)
`k_ion`(E)	Geometric focusing force due to ion column for given plasma density as a function of E
