LCODE (K.V.Lotov, 1995-2002)
-
2-dimensional geometry (plane or axisymmetric) - all further
formulae are for axisymmetric case, for definiteness.
-
Originally developed for studies of
plasma wakefield acceleration, with all proper simplifying assumptions
explicitly used:
-
Simulation window moves with the light
velocity
-
Accompanying reference frame used
-
No information can propagate in simulation
window in forward direction
-
Quasi-static
approximation (the beam changes slowly):
-
plasma response computed as for "rigid"
beam
-
long time step for beam particles
-
Beam is modelled by macro-particles
(fully relativistic)
-
Plasma is modelled by macro-particles
(fully relativistic)
-
Fields are calculated from full
Maxwell equations
-
Fluid description of the plasma
is possible (faster)
-
Capture of plasma particles to the
wave can be included
