All Implemented Interfaces:

TrackingObserver

public class TLPhaseSpaceObserver
extends PhaseSpaceObserver

A phase space observer which extends the PhaseSpaceObserver class. This class is used to register the phase space coordinates of particles in a beam hitting this observer. It is used by the TLBeamTracker class. The phase space coordinates are written to a file when the tracking is finished. This is done by @TLBeamTracker} class.

Constructor Details

TLPhaseSpaceObserver

public TLPhaseSpaceObserver(double longiPos,
 double radius,
 ReferenceOrbit orbit,
 double nominalMomentum,
 boolean backward)

Constructor for a phase space observer in a transfer line.

Parameters:

longiPos - Longitudinal position from the beginning of the line [m].

radius - Radius of the disk. Should be big enough to cover the aperture.

orbit - The reference orbit

nominalMomentum - The nominal momentum [GeV/c]

Method Details

observe

Specified by:

observe in interface TrackingObserver

Overrides:

observe in class PhaseSpaceObserver

Parameters:

p - Particle to observe

finish

public void finish(Particle p)

Description copied from interface: TrackingObserver

Finishes the tracking of the given particle.

Specified by:

finish in interface TrackingObserver

Overrides:

finish in class PhaseSpaceObserver

Parameters:

p - the particle to stop tracking

writeToFile

public void writeToFile(String file)

Write the phase space coordinates of the particle in a beam hitting this observer to a file.

Parameters:

file - The file to write to.

getMap

public Map<Particle,PhaseSpaceCoordinates> getMap()
