Pixel Vertex Detector (inside beam vacuum):

• 31 tracking stations distributed over 128 cm (± 64 cm)

• Each tracking station has 2 pixel planes arranged in ìviewsî (y,x)

• Each plane has over 500,000 pixels in a 10 x 10 cm area (square beam hole)

• Each pixel is 50 x 400 m in size (pulse height measurement for each pixel)
