SIS-100. Beam pipe geometry created with create_bpipe_geometry_v14k.C pipe_v14k = pipe_v14e + fixed sizes of vacuum chamber for mvd_v14a The beam pipe is composed of aluminium with a thickness proportional to the diameter (D(z)mm/60). It is placed directly into the cave as mother volume. The beam pipe consists of few sections (including RICH/MUCH section). Each section has a PCON shape (including windows). There are two windows: first one @ 220mm with R600mm and 0.7mm thickness, second one of iron @ 6000mm with R600mm and 0.2mm thickness. The STS section is composed of cylinder D(z=220-500mm)=36mm and cone (z=500-1700mm). All sections of the beam pipe with conical shape have half opening angle 2.5deg. The PSD section of the beam pipe is missing because it is planned that it will be part of PSD geometry.
