std::optional< std::string > name = std::nullopt )
inline

A thin collimator element that applies a transverse aperture boundary. Particles outside the boundary are considered lost.

Parameters
shapeaperture shape
actionspecify action of domain (transmit/absorb)
aperture_xhorizontal half-aperture (m)
aperture_yvertical half-aperture (m)
repeat_xhorizontal period for repeated masking, optional (m)
repeat_yvertical period for repeated masking, optional (m)
shift_odd_xfor hexagonal/triangular mask patterns: horizontal shift of every 2nd (odd) vertical period by repeat_x / 2. Use alignment offsets dx,dy to move whole mask as needed.
dxhorizontal translation error in m
dyvertical translation error in m
rotation_degreerotation error in the transverse plane [degrees]
namea user defined and not necessarily unique name of the element

static

◆ compute_constants()

void impactx::elements::Aperture::compute_constants ( RefPart const & refpart)
inline

Compute and cache the constants for the push.

In particular, used to pre-compute and cache variables that are independent of the individually tracked particle.

Parameters
refpartreference particle (unused)

◆ operator()()

template<typename T_Real = amrex::ParticleReal, typename T_IdCpu = uint64_t>
AMREX_GPU_HOST_DEVICE AMREX_FORCE_INLINE void impactx::elements::Aperture::operator() ( T_Real &AMREX_RESTRICT x,
T_Real &AMREX_RESTRICT y,
T_Real &AMREX_RESTRICT t,
T_Real &AMREX_RESTRICT px,
T_Real &AMREX_RESTRICT py,
T_Real &AMREX_RESTRICT pt,
T_IdCpu &AMREX_RESTRICT idcpu,
RefPart const &AMREX_RESTRICT refpart ) const
inline

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

Parameters
xparticle position in x
yparticle position in y
tparticle position in t (unused)
pxparticle momentum in x
pyparticle momentum in y
ptparticle momentum in t (unused)
idcpuparticle global index
refpartreference particle (unused)

◆ transport_map()

AMREX_GPU_HOST AMREX_FORCE_INLINE Map6x6 impactx::elements::Aperture::transport_map ( RefPart const &AMREX_RESTRICT refpart) const
inline

This function returns the linear transport map.

Parameters
[in]refpartreference particle
Returns
6x6 transport matrix
