Detailed Description

Geometry properties of a vertex detector needed for reconstruction code.

The vertex is assumed to consist of a number of layers. Each layer consists of a number of rectangular ladders that are uniformly distributed in a circle around the IP.
The sensitive volumes can be placed relative to the (insensitive) ladders.

See also:

addLayer .

The shell is described by outer and inner radius and it's half length in z.

The gap is assumed to be symetrical around z==0 and goes through all layers and ladders.

virtual void gear::VXDParametersImpl::addLayer (  int  nLadders, double  phi0, double  ladderDistance, double  ladderOffset, double  ladderThickness, double  ladderLength, double  ladderWidth, double  ladderRadLength, double  sensitiveDistance, double  sensitiveOffset, double  sensitiveThickness, double  sensitiveLength, double  sensitiveWidth, double  sensitiveRadLength )  [inline, virtual]

adding a Layer to the vertex one layer consiste of a number of ladders and sensitive areas (nLadders) that are each equidistant to IP. They are cubic with dimensions length (z), width (perpendicular to connection IP-spacepoint) and thickness (extension to connection IP-spacepoint). Parameters: nLadders  the number of ladders and sensitive areas inside the layer phi0  the starting angle for straight connection to the spacepoint Distance  the length (mm) of the straigth line between IP and spacepoint to ladder (ladderDistance) or sensitive Area (sensitiveDistance) Offset  the offset of ladder (ladderOffset) or sensitive area (sensitiveOffset) in clockwise direction in mm between spacepoint and middle of ladder/sensitive Thickness  the thickness in mm of the ladder (ladderThickness) or the sensitive area (sensitiveThickness) Length  the length (z-direction) in mm of the ladder (ladderLength) or the sensitive area (sensitiveLength) Width  the width of the ladder (ladderWidth) or the sensitive area (sensitiveWidth) in mm in clockwise direction RadLenght  the radiation lenght of the ladder (ladderRadLength) or the sensitive area (sensitiveRadLength) in mm
