CompositeProbe

public CompositeProbe(CompositeField field)

Create a composite probe from a composite field.

Parameters:

field - the composite field

Method Details

field

public void field(int sector,
 float x,
 float y,
 float z,
 float[] result)

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

Specified by:

field in interface IField

Overrides:

field in class FieldProbe

Parameters:

sector - the sector [1..6]

x - the x sector coordinate in cm

y - the y sector coordinate in cm

z - the z sector 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 x,
 float y,
 float z,
 float[] result)

Description copied from interface: IField

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

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.

isZeroField

public boolean isZeroField()

Checks whether the field has been set to always return zero.

Specified by:

isZeroField in interface IField

Overrides:

isZeroField in class FieldProbe

Returns:

true if the field is set to return zero.

gradient

public void gradient(float x,
 float y,
 float z,
 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 FieldProbe

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.

hasTorus

public boolean hasTorus()

Check whether we have a torus field

Returns:

true if we have a torus

hasSolenoid

public boolean hasSolenoid()

Check whether we have a solenoid field

Returns:

true if we have a solenoid
