Detailed Description

Quadrupole lense data structure.

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

Member Function Documentation

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

x	The X component of the space point in Cartesian coordinates (x,y) in [cm]
y	The 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

x	The X component of the space point in Cartesian coordinates (x,y) in [cm]
y	The 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].

Definition at line 80 of file BFieldComponentQuad.h.

operator+=()

ParamPoint3& operator+= ( const ParamPoint3 &  t )

inline

Parameters

t	the lense structure to add

Returns

reference to resulting lense structure
