class Acts::CylinderVolumeBounds : public Acts::VolumeBounds

[0] and [1] at positive \( \phi \)

Bounds for a cylindrical Volume, the orientedSurfaces(..) method creates a vector of up to 6 surfaces:

case A) 3 Surfaces (full cylindrical tube): BoundarySurfaceFace [index]:

  • negativeFaceXY [0] : Acts::DiscSurface with \( r_{inner}=0 \), parallel to \( xy \) plane at negative \( z\)

  • positiveFaceXY [1] : Acts::DiscSurface with \( r_{inner}=0 \), parallel to \( xy \) plane at positive \( z\)

  • cylinderCover [2] : Acts::CylinderSurface confining the Acts::Volume

case B) 4 Surfaces (tube with inner and outer radius): BoundarySurfaceFace [index]:

  • negativeFaceXY [0] : Acts::DiscSurface with \( r_{inner}>0 \), parallel to \( xy \) plane at negative \( z\)

  • positiveFaceXY [1] : Acts::DiscSurface with \( r_{inner}>0 \), parallel to \( xy \) plane at positive \( z\)

  • tubeOuterCover [2] : Acts::CylinderSurface with \( r = r_{outer} \)

  • tubeInnerCover [3] : Acts::CylinderSurface with \( r = r_{inner} \)

case C) 6 Surfaces (sectoral tube with inner and outer radius): BoundarySurfaceFace [index]:

  • negativeFaceXY [0] : Acts::DiscSurface with \( r_{inner}>0\) and \( \phi < \pi \), parallel to \( xy \) plane at negative \(z\)

  • positiveFaceXY [1] : Acts::DiscSurface with \( r_{inner}>0 \) and \( \phi < \pi \), parallel to \( xy \) plane at positive \(z\)

  • tubeSectorOuterCover [2] : Acts::CylinderSurface with \( r = r_{outer}\)

  • tubeSectorInnerCover [3] : Acts::CylinderSurface with \( r = r_{inner} \)

  • tubeSectorNegativePhi [4] : Rectangular Acts::PlaneSurface attached to [0] and [1] at negative \( \phi \)

    • tubeSectorNegativePhi [5] :
