 The volumes:
    TRD1-3     (Air)   --- The TRD mother volumes for one sector.
                           To be placed into the spaceframe.

    UAFI(/M/O) (Al)    --- The aluminum frame of the inner(/middle/outer) chambers (readout)
    UCFI(/M/O) (C)     --- The carbon frame of the inner(/middle/outer) chambers
                           (driftchamber + radiator)
    UAII(/M/O) (Air)   --- The inner part of the readout of the inner(/middle/outer) chambers
    UFII(/M/O) (Air)   --- The inner part of the chamner and radiator of the
                           inner(/middle/outer) chambers

 The material layers in one chamber:
    UL01       (G10)   --- The gas seal of the radiator
    UL02       (CO2)   --- The gas in the radiator
    UL03       (PE)    --- The foil stack
    UL04       (Mylar) --- Entrance window to the driftvolume and HV-cathode
    UL05       (Xe)    --- The driftvolume
    UL06       (Xe)    --- The amplification region

    UL07       (Cu)    --- The pad plane
    UL08       (G10)   --- The Nomex honeycomb support structure
    UL09       (Cu)    --- FEE and signal lines
    UL10       (PE)    --- The cooling devices
    UL11       (Water) --- The cooling water
