Version

1.0

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

Constructor & Destructor Documentation

BmnSsdStation() [1/2]

BmnSsdStation::BmnSsdStation

(

)

Default constructor

Definition at line 25 of file BmnSsdStation.cxx.

BmnSsdStation() [2/2]

BmnSsdStation::BmnSsdStation	(	const char *	name,
		const char *	title,
		TGeoPhysicalNode *	node = NULL
	)

Standard constructor

Parameters

name	Station name
title	Station type
node	Pointer to corresponding TGeoPhysicalNode

Member Function Documentation

AddLadder()

void BmnSsdStation::AddLadder

(

BmnSsdElement *

ladder

)

Add a ladder to the station

Definition at line 64 of file BmnSsdStation.cxx.

References BmnSsdElement::GetLevel(), and kSsdLadder.

GetRadLength()

Double_t BmnSsdStation::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.

Definition at line 60 of file BmnSsdStation.h.

GetSensorD()

Double_t BmnSsdStation::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.

Definition at line 72 of file BmnSsdStation.h.

GetSensorPitch()

Double_t BmnSsdStation::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.

GetSensorRotation()

Double_t BmnSsdStation::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.

Definition at line 97 of file BmnSsdStation.h.

GetSensorStereoAngle()

Double_t BmnSsdStation::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.

Definition at line 168 of file BmnSsdStation.cxx.

GetXmax()

Double_t BmnSsdStation::GetXmax ( ) const

inline

Definition at line 115 of file BmnSsdStation.h.

GetXmin()

Double_t BmnSsdStation::GetXmin ( ) const

inline

Minimal and maximal x and y coordinates

Definition at line 114 of file BmnSsdStation.h.

GetYmax()

Double_t BmnSsdStation::GetYmax ( ) const

inline

Definition at line 117 of file BmnSsdStation.h.

GetYmin()

Double_t BmnSsdStation::GetYmin ( ) const

inline

Definition at line 116 of file BmnSsdStation.h.

GetZ()

Double_t BmnSsdStation::GetZ ( ) const

inline

Station z position in global c.s. @value z Position of station in global C.S. [cm]

Calculated from the sensor positions (mean between min z and max z)

Definition at line 125 of file BmnSsdStation.h.

Init()

void BmnSsdStation::Init

(

)

Initialise the station parameters.
