CLIC01_ILD

This is an overview over what is in the simulation. Some parameters can be found in this table: Clic01Numbers

Note: Typos do happen, if something looks wrong it could very well be wrong.

Sub Detectors

Vertex Detector

The geometry of the vertex detector and the forward tracking disks is being studied by WG3.

The barrels are composed of 50 micron thick sensitive silicon, with the following inner radii and |z| extents: The silicon is placed inside the given radius. Outside the silicon a 134 micron thick support and electronics layer is placed. The ILD Vertex Detector consists of three double layers, each layer is made out of several ladders.

Note that in the current simulation the HCal endcap is also made with tungsten absorbers. This will probably be changed to iron/steel absorbers.

Computing Details

Most of this is obsolete with the newer Mokka versions

  • 4 Tesla Solenoid Field, corresponding to the ILD (down from 5 Tesla for CILD00)
  • The HCal Radiator(absorber) Material is now TungstenDens24, (same as for the CLID_01_SiD), with 1cm Thickness and 77 layers
  • NB: The increase in layers needs a small change in the Mokka sourcecode: in source/Geometry/Tesla/include/SD.hh "#define MAX_LAYERS 64" has to be set to something larger than 76
  • To use other materials than iron or WMod as the absorber, changes have to be made to source/Geometry/LDC/src/SHcalSc02.cc after "// Set up the Radiator Material to be used"
  else if(Hcal_radiator_material == "TungstenDens24")
    RadiatorMaterial =  CGAGeometryManager::GetMaterial("TungstenDens24");
The Material also has to be present in the Database.
