Constructor Details

Clas12FastMC

public Clas12FastMC(double torusScale,
 double solenoidScale)

constructor initialized part Monte-Carlo module module. arguments given are field strengths for torus and solenoid magnets. The scale value -1.0 is for in-bending configuration and +1.0 for out-bending.

Parameters:

torusScale - scale of the torus field relative to nominal

solenoidScale - scale of the solenoid field relative to nominal

Method Details

setSmearing

public void setSmearing(boolean isSmeared)

addResolutionFunc

public void addResolutionFunc(int pid,
 IParticleResolution res)

addDetector

public void addDetector(String name,
 Detector detector)

adds a detector to fast MC check list. with given cuts for each detector.

Parameters:

name -

detector - CLAS12 detector defined in geometry package

addFilter

public void addFilter(int charge,
 String[] d,
 int[] res)

add a detector filter for accepting particles, the filter will be applied only to particles with specified charge, and the arrays indicate the detector names and minimum number of hits for given detector. for example: addFilter(-1,new String[]{"DC","EC"},new int[]{36,9}); will require for negative particle to have minimum of 36 hits in DC and minimum of 9 hits in EC to be accepted. Many filters can be added to the fast MC module, and they work as OR. Particles can be detected in different detectors with different hit numbers, and as long as one filter works for particle with given charge, the particle will be accepted.

Parameters:

charge -

d -

res -

setDebugMode

public void setDebugMode(int mode)

set debug mode to control printout of the fast MC.

Parameters:

mode -

checkParticle

public boolean checkParticle(Particle part)

Swims particle through magnetic field and checks if all detector requirements are passed. returns false if any detector cut required is not satisfied.

Parameters:

part -

Returns:

getEvent

public PhysicsEvent getEvent(PhysicsEvent event)

getDetectorResponses

public Map<String,Integer> getDetectorResponses(Particle part)

showDetectorResponses

public void showDetectorResponses(Particle part)

show

public void show()
