SIS-100. Beam pipe geometry created with create_bpipe_geometry_v16c_1e.C pipe v16c_1e - is a pipe for the STS up to the interface to RICH at z = 1700 mm with a (blue) flange at the downstream end of the STS box The beam pipe is composed of carbon with a fixed wall thickness of 0.5 or 1.0 mm. It is placed directly into the cave as mother volume. The beam pipe consists of few sections up to the RICH section (1700-3700mm), which is part of the RICH geometry. Each section has a PCON shape (including windows). The STS section is composed of cylinder D(z=220-410mm)=34mm and cone (z=410-1183mm). All sections of the beam pipe with conical shape have half opening angle 2.5deg.
