4.1. PWFA¶

class scisalt.PWFA.Match(plasma, E, emit_n)[source]¶

Given a plasma of type Plasma and a beam of energy E in GeV and normalized emittance emit_n in SI units, calculates match parameters

beta(E)[source]¶: $\beta$ function of matched beam

emit_n¶: Emittance of beam

gamma¶: Relativistic $\gamma$ of beam

sigma¶: Spot size of matched beam

class scisalt.PWFA.Plasma(n_p=None, n_p_cgs=None)[source]¶

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

Input either:

Plasma density n_p in SI units
Plasma density n_p_cgs in CGS units

k_ion(E)[source]¶: Geometric focusing force due to ion column for given plasma density as a function of E

n_p¶: Plasma density in SI units

n_p_cgs¶: Plasma density in CGS units

w_p¶: Plasma frequency $\omega_p$ for given plasma density
