Detailed Description

Class representing a station of the StsSystem.

Author: V.Friese v.fri.nosp@m.ese@.nosp@m.gsi.d.nosp@m.e

Version: 1.0

The StsStation class represents one level in the STS element hierarchy. It holds station-wide parameters like z position, sensor thickness, and material budget for use in reconstruction tasks.

◆ AddLadder()

void CbmStsStation::AddLadder ( CbmStsElement * ladder )

Add a ladder to the station

◆ CheckSensorProperties()

void CbmStsStation::CheckSensorProperties ( )

private

Check properties of sensors (position, thickness) The z position of the station is determined as the mean of the minimum and maximum z positions of all sensors within the station. The active thickness of the first sensor is defined as thickness of the entire station. A warning is given out if there are different thicknesses among the sensors in the stations.

◆ GetRadLength()

Double_t CbmStsStation::GetRadLength ( ) const

inline

Radiation length of the main material of the station (silicon) @value Radiation length of silicon [cm]

Required from L1/KF. The value for silicon is hard-coded here, since it is not likely that the material will change.

◆ GetSensorD()

Double_t CbmStsStation::GetSensorD ( ) const

inline

Sensor thickness @value Thickness (extension in z) of first sensor [cm]

This return the thickness of the first sensor in the station. Needed by L1/KF. Note that in general, sensors of different thicknesses can be in the station. In this case, a warning message is issued when the station properties are initialised.

◆ GetSensorPitch()

Double_t CbmStsStation::GetSensorPitch ( Int_t iSide ) const

Get sensor strip pitch

Parameters

iSide Sensor side (0 = front, 1 = back) @value Strip pitch [cm]

This return the strip pitch of the first sensor in the station. Valid only for sensors of type DSSD. Needed by L1/KF. Note that in general, sensors of different pitches can be in the station.

Returns -1 if there are no sensors in the station or the first sensor is not of type DSSD.

◆ GetSensorRotation()

Double_t CbmStsStation::GetSensorRotation ( ) const

inline

Sensor rotation @value Rotation of first sensor in station in global C.S. [rad]

This return the rotation angle in the x-y plane of the first sensor in the station w.r.t. the global C.S. Needed by L1/KF. Note that in general, the rotation angle will be different for each sensor. In particular, half of them are upside down.

◆ GetSensorStereoAngle()

Double_t CbmStsStation::GetSensorStereoAngle ( Int_t iSide ) const

Get sensor stereo angle

Parameters

iSide Sensor side (0 = front, 1 = back) @value Stereo angle [degrees]

This return the strip stereo angle of the first sensor in the station. Valid only for sensors of type DSSD. Needed by L1/KF. Note that in general, sensors of different stereo angles can be in the station.
