Detailed Description

This detector builder is responsible for constructing sensitive and inactive Sti volumes describing the material of the SST detector. The corresponding SST detector geometry is described in AgML files in StarVMC/Geometry/

Constructor & Destructor Documentation

StiSstDetectorBuilder::StiSstDetectorBuilder ( bool  active,
bool  buildIdealGeom = true 

Builds an object to direct the construction of Sti detectors/volumes.

activeSet to true when accounting for hits in active volumes or false otherwise
buildIdealGeomSet to true (default) to ignore volume position transformation stored in the survey DB tables

Member Function Documentation

void StiSstDetectorBuilder::buildDetectors ( StMaker source)

Creates all Sti volumes of the SST detector.

Reimplemented from StiDetectorBuilder.

void StiSstDetectorBuilder::buildInactiveVolumes ( )

Creates a crude model of the SST detector. The geometry is modeled with tubes segmented in z and r. The dimensions and other physical properties of the tube volumes are determined manually by looking at distribution of the material in the ROOT TGeo geometry.

We use the following dimensions and material properties:

SFMO_CENTER_IN: 22.2 < r < 23.5 cm -34.25 < z < 34.25 cm Z = 7.38471 A = 14.7875 Dens = 0.1777280 X0 = 28128.1 SFMO_CENTER_MID: 23.5 < r < 25.8 cm -34.25 < z < 34.25 cm Z = 7.29364 A = 14.5971 Dens = 0.0147153 X0 = 30146.9 SFMO_CENTER_OUT: 25.8 < r < 27.0 cm -34.25 < z < 34.25 cm Z = 7.27831 A = 14.5655 Dens = 0.0372666 X0 = 29681.4

SFMO_LEFT_IN: 22.2 < r < 23.5 cm -51.50 < z < -34.25 cm Z = 7.90551 A = 15.8598 Dens = 0.5131150 X0 = 21711.5 SFMO_LEFT_MID: 23.5 < r < 25.0 cm -49.50 < z < -34.25 cm Z = 7.67447 A = 15.3544 Dens = 0.3013760 X0 = 23510.2 SFMO_LEFT_OUT: 25.0 < r < 26.5 cm -49.50 < z < -34.25 cm Z = 7.52669 A = 15.0602 Dens = 0.2235500 X0 = 25904.3

SFMO_RIGHT_IN: 22.2 < r < 23.5 cm 34.25 < z < 51.50 cm Z = 7.92641 A = 15.9019 Dens = 0.5298270 X0 = 21402.6 SFMO_RIGHT_MID: 23.5 < r < 25.0 cm 34.25 < z < 49.50 cm Z = 7.66531 A = 15.3361 Dens = 0.2953080 X0 = 23582.3 SFMO_RIGHT_OUT: 25.0 < r < 26.5 cm 34.25 < z < 49.50 cm Z = 7.53069 A = 15.0682 Dens = 0.2273420 X0 = 25831.5

The inner radius of the central tube is increased by 0.85 cm to avoid overlap with sensitive layers, and the density of that volume is scaled accordingly.

std::string StiSstDetectorBuilder::formTGeoPath ( int  ladder,
int  sensor 

Returns a TGeo path to the sensor in the given ladder.

Returns a full path to the SST sensor placed in a predifined location in the detector's ROOT geometry. An empty string is returned if the sensor not found in the geometry hierarchy (via gGeoManager).

void StiSstDetectorBuilder::useVMCGeometry ( )

Builds active Sti volumes by creating Sti shapes corresponding to the sensors of the SST detector. The created Sti detectors are positioned using either the ideal (ROOT's TGeo gGeoManager) or missaligned geometry from the STAR database via object of the StSstDbMaker class.

Reimplemented from StiDetectorBuilder.
