<!-- TBH4 geometry driver file. B. Heltsley, Feb 27, 2007
This file should not need modification for production simulation.
The tunable numbers that must be passed around are in the
files ebcon.xml and tbrot.xml. Other tunables that
are only needed for the beam line definition appear below
(for example, positions of hodoscopes and trigger counters).
The two numbers theta and phi specifying the angle
of the beam into the supermodule are at the top of tbrot.xml.
To vary that angle, modify that file.
The hierarchy is as follows:
OCMS is a big box and the world volume
CMSSE is the same size as OCMS and its child.
TBH4BeamLine is a long tube with the beam line inside CMSSE.
CALO is a phi-slice of a polycone to hold ECAL.
ECAL is a phi-slice of a polycone to hold EBAR.
EBAR is a phi slice of a polycone to hold ESPM.
In this way the normal CMS hierarchy is preserved.
To maintain compatibility with normal CMS simulation,
eregalgo.xml in this directory defines a logical
volume ECAL which is the same size as OCMS
and is its child. This is because the barrel must
be a child of eregalgo:ECAL.
The beam line TBH4BeamLine is a narrow and long tube holding
the sections of vacuum, windows, trigger counters,
and hodoscope. This is a child of ECAL.
The barrel itself is narrowed into a phi section
to allow entry of the beam into the detector.
It is a child of eregalgo:ECAL. A single supermodule
is placed inside this barrel.
The normal ebalgo.xml and ebrot.xml files from EcalCommonData are used
in conjunction with the test beam files. It receives
some modifications from the constants defined in
these files.
