Detailed Description

Factory for the Target (proton target and shielding) geometry.

Implements the 2026 BDF target design, extracted from CATIA model ST1A07710_01_AB.02 and simplified to axisymmetric shapes:

• Vacuum box containing shielding and target assembly
• Copper proximity, top, and bottom shielding
• Iron shielding pedestal
• Helium container (HeVolume) holding:
  • 33 solid tungsten disks (no cladding); the last disk (rear block) has a larger radius
  • steel core (the two clamp halves modelled as one axisymmetric polycone) with serpentine He cooling grooves subtracted
  • steel jacket tube with front and rear flanges; the gap between core and jacket is a He annulus
  • upstream beam window (dished membrane simplified to a flat disc preserving the 8 mm of steel on the beam axis) with its nose ring, and the bore rings of the upstream cover plate
  • domed rear endcap (8 mm shell, dome approximated as a polycone)
• Upstream cover plate (rectangular, asymmetric about the beam axis), the part outside the He container

All target z coordinates are measured from the front face of the first disk, which is the SHiP global origin.
