Detailed Description

Quadrupole lense data structure.

This is a flat structure so magnetic field has only X and Y components

◆ getBx()

double getBx ( double  x,
double  y 
) const
inline

Calculates the X component of the magnetic field vector at the specified space point from a quadrupole lense.

Parameters
xThe X component of the space point in Cartesian coordinates (x,y) in [cm]
yThe Y component of the space point in Cartesian coordinates (x,y) in [cm]
Returns
The X component of magnetic field vector at the given space point in [T].

Definition at line 71 of file BFieldComponentQuad.h.

◆ getBy()

double getBy ( double  x,
double  y 
) const
inline

Calculates the Y component of the magnetic field vector at the specified space point from a quadrupole lense.

Parameters
xThe X component of the space point in Cartesian coordinates (x,y) in [cm]
yThe Y component of the space point in Cartesian coordinates (x,y) in [cm]
Returns
The Y component of magnetic field vector at the given space point in [T].
