public RotatedCompositeProbe(RotatedCompositeField field)

Method Details

field

public void field(int sector,
 float xtilt,
 float ytilt,
 float ztilt,
 float[] result)

Obtain the magnetic field at a given location expressed in Cartesian coordinates of the tilted sector system. The field is returned as a Cartesian vector in kiloGauss.

Specified by:

field in interface IField

Overrides:

field in class CompositeProbe

Parameters:

sector - the sector [1..6]

xtilt - the tilted x coordinate in cm

ytilt - the tilted y coordinate in cm

ztilt - the tilted z coordinate in cm

result - the result is a float array holding the retrieved field in kiloGauss. The 0,1 and 2 indices correspond to x, y, and z components.

field

public void field(float xs,
 float ys,
 float zs,
 float[] result)

Obtain the magnetic field at a given location expressed in Cartesian coordinates. The field is returned as a Cartesian vector in kiloGauss. THIS ASSUMES COORDINATES ARE IN A SECTOR 1 SECTOR SYSTEM

Specified by:

field in interface IField

Overrides:

field in class CompositeProbe

Parameters:

xs - the x coordinate in cm in sector 1 sector system

ys - the y coordinate in cm in sector 1 sector system

zs - the z coordinate in cm in sector 1 sector system

result - the result is a float array holding the retrieved field in kiloGauss. The 0,1 and 2 indices correspond to x, y, and z components.

gradient

public void gradient(float xs,
 float ys,
 float zs,
 float[] result)

Obtain an approximation for the magnetic field gradient at a given location expressed in Cartesian coordinates. The field is returned as a Cartesian vector in kiloGauss/cm.

Specified by:

gradient in interface IField

Overrides:

gradient in class CompositeProbe

Parameters:

x - the x coordinate in cm

y - the y coordinate in cm

z - the z coordinate in cm

result - a float array holding the retrieved field in kiloGauss. The 0,1 and 2 indices correspond to x, y, and z components.
