Difference: EndcapLayout (5 vs. 6)

Pixel Endcaps in the LoI (Cartigny) Layout
Line: 7 to 7

The closest match to the requested dimensions are illustrated in the drawings above. These disks use 'quad' modules (modules built on 4 FEI4 chips in a 2x2 grid placement) and 'hex' modules (built on 6 chips in a 2x3 grid). Disks 1-4 would have the 'QHH' geometry shown in the leftmost picture ('QHH' for Quad-Hex-Hex as the innermost ring is made of quad modules and the middle and outer rings are made of hex modules). Disk 5 is QQH and Disk 6 is QH. This results in the dimensions shown in the table below:

z (mm) Rinner (active) (mm) Router (active) (mm)
822 150.1 315.0
960 150.1 315.0
1140 150.1 315.0
1360 150.1 315.0
1600 170.6 315.0
1890 212.4 315.0
Module Dimensions assumed: (to add)
Dimensions assumed:
  • 0.45mm gap between adjacent FEI4s in a module
  • sensor dead edge 0.2mm radially
  • a hex module is 61.3mm long radially
  • a quad module is 40.85mm long radially
  • >0.2mm gap required between adjacent modules on a disk, to isolate HV
