Detector Geometry

The geometry of the MEG detector is designed by Mechanical Desktop (MDT). The common information on the geometry can be owned jointly with the CAD files among the collaborators.

• MEG CAD files (ver.1.0)
  This version describes only simple information on the detector geometry. However, it can provide the boundary condition for a basic design of each detector component. Note that the detector geometry is still being optimized and the geometry described in this version is not a final one.
  The CAD files included in this version are as follows.

  Detector	File name	Contents
  Magnet	magnet.awg, magnet.xls	coils, outermost vessels
  LXe calorimeter	calorimeter.awg, calorimeter.xls	LXe, inner vessel, outer vessel
  Drift chamber	chamber.awg, chamber.xls	outline
  Timing counter	tof.awg, tof.xls	outline
  Assembly	assembly.awg, assembly.xls	-

  Excel file (*.xls) is optional. It describes the same parameters on the geometry as used in the corresponding CAD file (*.awg). If the table of the global variables on the MDT is linked to the Excel file, versions with different sets of the parameter values are easily handled by using the Excel file.
  The file, assembly.awg is made by putting together all the CAD files considering the detector arrangement. If necessary, the information of each detector component can be exported to the external CAD file which will be equivalent to the CAD file originally provided for each detector component. Modification to the exported CAD file will be reflected in the assembly.awg. The detector picture drawn by using assembly.awg is shown here. PS file of the picture (17MB!) is also available.
