Method Detail

doPropagation

public void doPropagation(IProbe probe,
                          IElement elem)
                   throws ModelException

Propagates the probe through the element.

Specified by:

doPropagation in class Tracker

Parameters:

probe - probe to propagate

elem - element acting on probe

Throws:

ModelException - invalid probe type or error in advancing probe

See Also:

Tracker.advanceProbe(gov.sns.xal.model.IProbe, gov.sns.xal.model.IElement, double), Tracker.validProbe(gov.sns.xal.model.IProbe)

compStepCount

protected int compStepCount(IElement elem)

Returns the number of subsections to break the specified element in to for propagation. Currently returns the ceiling of the element length divided by the space charge interval. This should be re-evaluated when the ensemble algorithm is fleshed out.

Parameters:

elem - Element currently acting on probe

Returns:

ceiling of element length divided by space charge interval

advanceState

protected void advanceState(IProbe probe,
                            IElement elem,
                            double dblLen)
                     throws ModelException
