PWFA

The PWFA module makes scientific calculations for plasma wakefield acceleration (PWFA) much simpler. It is used in various simulations. It is currently not unit tested.

Beam Classes

RoundBeam(nb0, s_r[, E, dE])	Creates a beam with circularly-symmetric properties.
EllipseBeam(nb0[, E, dE, sx, sxp, sxxp, ...])	Creates an ellipsoidal beam.

Ion Classes

Ions1D(species, N_e, sig_x, sig_y, sig_xi[, ...])	A class to facilitate calculating ion motion in PWFA ion columns due to planar, infinitely-long gaussian beams.
Ions2D(species, N_e, sig_r, sig_xi[, ...])	A class to facilitate calculating ion motion in PWFA ion columns due to cylindrical, infinitely-long gaussian beams.

Matching Classes

Match(plasma, E, emit_n)	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
MatchPlasma(E, emit_n, sigma)	Given a beam of energy E in GeV with normalized emittance

Plasma Class

Plasma([n_p, n_p_cgs, species])

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