 theXChannelBoundaries positions are the x low limits for each channel (EM section)
 theZLUMChannelBoundaries are the z low limits for each channel (LUM section)
 theZHadChannelBoundaries are the z low limits for each HAD channel at y = 0 position
 this coordinates are given with respect to the center of the enclosing volume (ZDC)
 as defiened in the geometry: X0,Z0,Y0
 tiltangle is the angle of the HAD section
 YLUM is the Y position of LUM 
 dYPlate  is half height (DY/2) of the HAD and LUM sections
 dYLum is the half height (DY/2) of the LUM section
 dXPlate is the half width (DX/2) of all sections	
 all dimmensions are in mm and rads
