Detailed Description

Every dimension the SBT geometry is parameterised by (mm).

A literal aggregate, so a perturbed copy is itself a constant expression:

constexpr SBTParams taller = [] { SBTParams p = kSBT;
                                  p.hbeamHeight = 400.0; return p; }();

That is what lets test_decayvolume exercise configurations other than the shipped one — which is the only way to test that the helium derivation is right in general, rather than right at today's numbers — without any of the derivation becoming runtime state.
