Constructor & Destructor Documentation

◆ CFbend()

impactx::CFbend::CFbend ( amrex::ParticleReal const  ds,
amrex::ParticleReal const  rc,
amrex::ParticleReal const  k,
int const  nslice 
)
inline

An combined-function bend, consisting of an ideal sector bend with an upright quadrupole focusing component.

Parameters
dsSegment length in m.
rcRadius of curvature in m.
kQuadrupole strength in m^(-2) (MADX convention) = (gradient in T/m) / (rigidity in T-m) k > 0 horizontal focusing k < 0 horizontal defocusing
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::CFbend::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 cfbend functor, so that a variable of this type can be used like a cfbend 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::CFbend::operator() ( RefPart &AMREX_RESTRICT  refpart) const
inline

This pushes the reference particle.

Parameters
[in,out]refpartreference particle
