Detailed Description

Construct the exposed part of the CAPTAIN detector. This builds exposed parts of the TPC that are in the argon gas. The exposed volume is returned as a cylinder filled with liquid argon.

Member Function Documentation

double CaptImmersedBuilder::GetHeight

(

)

Get the height of the exposed region. This is calculated.

Definition at line 62 of file CaptImmersedBuilder.cc.

                                      {
    CaptDriftRegionBuilder& drift = Get<CaptDriftRegionBuilder>("Drift");
    double height = drift.GetHeight();
    return height;
}

G4ThreeVector CaptImmersedBuilder::GetOffset ( )

inline

Return the offset of the intended origin of the volume relative to the center of the logical volume. To get the origin at the right location (say originPosition), the logical volume should be positioned at originPosition-GetOffset(). The offset is defined by the bottom of the wire plane assembly (a decision will be made in the future as to whether this is the bottom of the grid, or the bottom of the V plane. This means that the wires for the V plane are at a (very) small positive z coordinate.

Definition at line 32 of file CaptImmersedBuilder.hh.

{return fOffset;}

G4LogicalVolume * CaptImmersedBuilder::GetPiece ( void  )

virtual

Construct and return a G4 volume for the object. This is a pure virtual function, which means it must be implemented by the inheriting classes. This returns an unplaced logical volume which faces along the Z axis.

All the space above the drift region.

Implements EDepSim::Builder.
