PXD consists of 2 layers of silicon pixel-type ladders which are arranged in so-called wind-mill structure and consist of 2 sensors. The sensors may either contain constant pixel size (CPS option) or variable pixel size (VPS option) along Z axis. In R-Phi direction the size is fixed and set up to 50 um (pixels are arranged in so-called bricked type structure). As the ladders (forming 2nd layer) can not be produced from one Si wafer, they are split up and mechanically fixed together by a Si support structure in the middle (400 um thick).

  • active part consists of Si ladders, resp. 2 Si pixel-type sensors (50 um thick)
  • passive part consists of Si support rims (450 um thick), Si support bridge (2nd layer, 400 um thick) and 12 Si switcher/1 ladder (300 um thick)
