Detailed Description

Factory for the DecayVolume subsystem (decay region + SBT).

Builds an air container holding the Surround Background Tagger — a steel H-beam supporting structure and LAB scintillator sensor cells forming a 50 m rectangular frustum — wrapped around a central helium decay volume. The SBT geometry is driven by sbt.toml (parsed into an SBTConfig).

The helium is not an independent volume: it is derived from where the SBT material actually is (see SBTEnvelope.h), so that it can neither overlap the structure and sensors nor leave an unphysical margin behind.

Z: 32.92 to 83.32 m -> centre 58.12 m; placement handled by SHiPGeometry.

Build the DecayVolume geometry; returns the air container.

◆ config()

inline

The config the last build() actually used.

Tests must reason about this, not a default-constructed SBTConfig: the geometry comes from sbt.toml, and a test that checks a clearance against the C++ default is validating a config it did not build.
