This is an approximation of the LDC01Sc detector in Mokka. The compact description of this detector in xml format can be found at http://www.lcsim.org/detectors/ldc01app.zip . What follows is a plain text description of the file compact.xml found in this zip file.
The tracking region is defined to be a cylinder with radius 158. cm and z extent +/- 229.95 cm.
Beampipe:
--------
The beampipe consists of cylinders and cones of Be and Fe. The inner radius of the central Be beampipe is 1 cm. A beam vacuum is defined inside the beampipe.
Luminosity Monitor:
