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
dsSegment length in m.
ezelectric field strength in m^(-1) = (charge * electric field Ez in V/m) / (m*c^2)
bzmagnetic field strength in m^(-1) = (charge * magnetic field Bz in T) / (m*c)
nslicenumber 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
pParticle AoS data for positions and cpu/id
pxparticle momentum in x
pyparticle momentum in y
ptparticle momentum in t
refpartreference 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]refpartreference particle
