Detailed Description

a REMI type spectrometer

class describes a remi type spectroemter that has one or more separeted regions. In the spectrometer a magenetic field can be present. In this case it is important to know in which direction the magnetic field is pointing and how strong it is. The latter can be measured by the cyclotron period of the electrons and the former by the rotation direction of the electrons.

User definable Parameters:

AcqirisDetectors/%detectorname%/Particles/%particlename%/Spectrometer/{BFieldIsOn}
Flag to tell whether a magnetic field is present in the spectrometer. Default is false

AcqirisDetectors/%detectorname%/Particles/%particlename%/Spectrometer/{RotationClockwise}
Flag to tell in which direction the magentic field is pointing This can be told by telling in which way the electrons rotate. If they rotate clockwise this should be true. Default is true.

AcqirisDetectors/%detectorname%/Particles/%particlename%/Spectrometer/{CyclotronPeriode}
The time it takes for an electron to make a complete rotation in the magnetic field in ns. Default is 10

AcqirisDetectors/%detectorname%/Particles/%particlename%/Spectrometer/{Regions}
The groupname of the regions of a spectrometer. See cass::ACQIRIS::SpectrometerRegion

AcqirisDetectors/%detectorname%/Particles/%particlename%/Spectrometer/Regions/{Size}
The number of spectrometer regions available. Default is 0.

load the settings from .ini file

load all spectrometer regions from file before loading our own members. We need to convert the cyclotron period that is given by the user in electron periods to the period that this particle has. Therefore we need to multiply the period by the ratio of mass to charge of the particle.
