Detailed Description

A class that constructs tunnel segments around a beamline.

It uses a beam line instance - the flat beam line and creates a new beam line of tunnel segments that can then be placed.

Decide whether this is a good point to break the tunnel based on various cumulative parameters.

◆ BuildTunnelSections()

BDSBeamline * BDSTunnelBuilder::BuildTunnelSections ( const BDSBeamline * flatBeamLine ) const

Main function of class - use tunnel factories and builds sections of tunnel around the flat beamline (of accelerator components). Tunnel segments are placed in order in a new beamline instance, which is returned.
