rotation_degree	rotation error in the transverse plane [degrees]
name	a user defined and not necessarily unique name of the element

Member Function Documentation

◆ compute_constants()

void impactx::elements::ShortRF::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

refpart reference particle

◆ operator()() [1/2]

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

inline

This pushes the reference particle.

Parameters

[in,out] refpart reference particle

◆ operator()() [2/2]

template<typename T_Real = amrex::ParticleReal, typename T_IdCpu = uint64_t>

AMREX_GPU_HOST_DEVICE AMREX_FORCE_INLINE void impactx::elements::ShortRF::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 a shortrf functor, so that a variable of this type can be used like a shortrf function.

The

See also: compute_constants method must be called before pushing particles through this operator.

Parameters

x	particle position in x
y	particle position in y
t	particle position in t
px	particle momentum in x
py	particle momentum in y
pt	particle momentum in t
idcpu	particle global index (unused)
refpart	reference particle (unused)

◆ transport_map()

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

inline

This function returns the linear transport map.

Parameters

[in] refpart reference particle

Returns: 6x6 transport matrix
