Detailed Description

A Particle.

class describing a particle. It contains the properties of a particle, classes that can calculate the momentum of the particle. Therefore it also contains the spectrometer through which the particle flys and a class that can correct the values from the detectorhit. To find out which of the provided detectorhits are a particle hit of this particle it owns a comparator class.

User definable Parameters:

AcqirisDetectors/%detectorname%/Particles/%particlename%/{Charge}
The charge of the particle in atomic units. Default is 1.

AcqirisDetectors/%detectorname%/%particlename%/{Mass}
The Mass of the particle in atomic mass units. When one wants to define a electron the charge has to be -1 and the Mass 1. Default is 1.

AcqirisDetectors/%detectorname%/Particles/%particlename%/{Spectrometer}
The Spectrometer that the Particles fly through. See cass::ACQIRIS::Spectrometer

AcqirisDetectors/%detectorname%/Particles/%particlename%/{Corrections}
The corrections that one has to do to the raw values of a hit in order to convert the hit values to momentum. See cass::ACQIRIS::HitCorrector

AcqirisDetectors/%detectorname%/Particles/%particlename%/{ConditionType}
The type of condition that we use to identify a particle hit from a detectorhit. Default is 0. Possible choises are:

0: condition on time of flight: See cass::ACQIRIS::TofCond
1: condition on a radius with choseable center of the position: See cass::ACQIRIS::RadCond
2: condition on a rectangle of the position: See cass::ACQIRIS::RectCond
3: combination of condition 0 and 1: See cass::ACQIRIS::TofCond and cass::ACQIRIS::RadCond
4: combination of condition 0 and 2: See cass::ACQIRIS::TofCond and cass::ACQIRIS::RadCond

inline

constructor

set the _listIsCreated flag to false

Definition at line 77 of file particle.h.

Member Function Documentation

void Particle::associate ( DelaylineDetector * detector )

tell which are the detector hits to search through

after telling us which detectohit list to go through to search for particle hits, this resets the _listIsCreated flag and clears the _particlehits container.

Parameters

detector pointer to the detector containing this particle

Definition at line 323 of file particle.cpp.

References detector.

double cass::ACQIRIS::Particle::charge_au ( ) const

inline

particleHits_t & Particle::hits ( )

retrieve the particle hits

goes through the detectorhits and checks whether the hit is a particle of our type. Then calculates the momenta in kartesian and polarcoordinates and puts the new hit into the list. Then returns the list. When the former is already done once, just return the list.

Returns: the list of particle hits

Definition at line 296 of file particle.cpp.

void Particle::loadSettings ( CASSSettings & s )

load the settings from .ini file

First load the spectrometers settings, then the hitcorrector settings. Then load our properties. Then create the comaprison object that the user has chosen and load its settings. After that depending on the spectrometer type load the momentum calculation objects. The mass is always converted from atomic mass units to atomic units. Only if the mass is 1 and the charge is -1 (this is true for an electron) the conversion will be omited.

Parameters

s	the CASSSettings object to read the info from
