0007 DIRC consists of 12 (default) identical modules making a barrel.
0008 Each DIRC module consists of:
0009 ________
0010 [ | \
0011 [ | \
0012 [MCP|Prism|Lens|--------bars+glue-----|mirror]
0013
0014 Main constants to control DIRC global geometry:
0015 - DIRC_length
0016 - DIRC_offset
0017 - DIRC_rmin
0018 - DIRC_rmax
0019 - DIRCBox_count (12 full dirc, 1 - a single module)
0020
0021 When DIRC_length is set, it affects bars length (all other lengths are fixed)
0022 The width of each DIRC module is derived from DIRCPrism_width
