Member Typedef Documentation

PType

using impactx::ChrAcc::PType = ImpactXParticleContainer::ParticleType

Constructor & Destructor Documentation

ChrAcc()

impactx::ChrAcc::ChrAcc ( amrex::ParticleReal const  ds, amrex::ParticleReal const  ez, amrex::ParticleReal const  bz, int const  nslice  )

inline

Acceleration in a uniform field Ez, with a uniform solenoidal field Bz.

The Hamiltonian is expanded through second order in the transverse variables (x,px,y,py), with the exact pt dependence retained.

Parameters

ds	Segment length in m.
ez	electric field strength in m^(-1) = (charge * electric field Ez in V/m) / (m*c^2)
bz	magnetic field strength in m^(-1) = (charge * magnetic field Bz in T) / (m*c)
nslice	number of slices used for the application of space charge

Member Function Documentation

operator()() [1/2]

AMREX_GPU_HOST_DEVICE AMREX_FORCE_INLINE void impactx::ChrAcc::operator() ( PType &AMREX_RESTRICT  p, amrex::ParticleReal &AMREX_RESTRICT  px, amrex::ParticleReal &AMREX_RESTRICT  py, amrex::ParticleReal &AMREX_RESTRICT  pt, RefPart const &  refpart  ) const

inline

This is a chracc functor, so that a variable of this type can be used like a chracc function.

Parameters

p	Particle AoS data for positions and cpu/id
px	particle momentum in x
py	particle momentum in y
pt	particle momentum in t
refpart	reference particle

operator()() [2/2]

AMREX_GPU_HOST_DEVICE AMREX_FORCE_INLINE void impactx::ChrAcc::operator() ( RefPart &AMREX_RESTRICT  refpart ) const

inline

This pushes the reference particle.

Parameters

[in,out]

refpart

reference particle
