Detailed Description

Class for constructing the geometry of the CBM target.

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

Since: 08.10.2013

The target of CBM can be created either on the fly, by specifying the target material (element), its thickness, its diameter and the density of the material. In this case, a single volume of shape TUBE will be positioned at the target position, as daughter of the node already present there. If no position is specified by the method SetPosition, the target is placed at the origin of the global coordinate system.

In case a geometry file is specified, the geometry will be constructed from this file in the same manner as for all other modules.

Constructor & Destructor Documentation

◆ CbmTarget() [1/4]

CbmTarget::CbmTarget ( )

Default constructor.

Definition at line 18 of file CbmTarget.cxx.

◆ CbmTarget() [2/4]

CbmTarget::CbmTarget ( const char * fileName )

Constructor with file name.

Parameters

fileName Name of geometry file

This constructor will force the target geometry to be constructed from a geometry file (ROOT format only).

Definition at line 34 of file CbmTarget.cxx.

◆ CbmTarget() [3/4]

CbmTarget::CbmTarget	(	const char *	element,
		Double_t	thickness,
		Double_t	diameter,
		Double_t	density = `-1.`

Constructor with target properties.

Parameters

element	Element name of target material (Full name or element symbol, e.g. "Gold", "Au");
thickness	Thickness in z [cm]
diameter	Diameter [cm]
density	Density [g/cm^3]. If negative (default), density under standard conditions will be taken, if available.

By using this constructor, the target geometry will be constructed as a tube with material and parameters specified as arguments.

Constructor with target properties.

Parameters

z	Atomic charge of target material element
thickness	Thickness in z [cm]
diameter	Diameter [cm]
density	Density [g/cm^3]. If negative, density under standard conditions will be taken.
