+// Detector consists of 3 sub-detectors FMD1, FMD2, and FMD3, each of

+//
+// This contains the coarse version of the FMD - that is, the
+// simulation produces no hits in the FMD volumes.
//
- // Create the geometry of Forward Multiplicity Detector version 0
- //
- //Detector consists of 6 volumes:
- // 1st covered pseudorapidity interval from 3.3 to 2.0
- // and placed on 65cm in Z-direction;
- // 2nd - from 2.0 to 1.6 and Z=85 cm;
- // 3d - the same pseudorapidity interval as the 1st
- // but on the other side from the interaction point z=-65cm;
- // 4th - simmetricaly with the 2nd :
- // pseudorapidity from 2.0 to 1.6, Z=-85cm
- // 5th - from 3.6 to 4.7, Z=-270cm
- // 6th - from 4.5 to 5.5 , Z=-630cm.
- // Each part has 400mkm Si (sensetive area, detector itself),
- // 0.75cm of plastic simulated electronics material,
- // Al support ring 2cm thickness and 1cm width placed on
- // the outer radius of each Si disk;
