Silicon Detectors
The MPI will procure appr. 3000 Silicon detectors for the forward SCT.
Detector types ordered:
| Detector type | pre-series | series | for |
| W12 | 30 | 600 | Freiburg, NIKHEF |
| W21 | 15 | 775 | MPI |
| W22 | 15 | 975 | MPI |
| W31 | 15 | 290 | Australia |
| W32 | 15 | 290 | Australia |
| total | 90 | 2930 | |
All detectors have been delivered.
Drawings of detector dimensions and positions of fidutial marks are

More information on detector design, prototyping and tests can be found in
the
HLL ATLAS page.
The detectors are produced by CiS
in Erfurt, Germany.
W21, W22, W31, W32 detectors will be produced on standard silicon, W12
detectors on oxygenated silicon in order to improve radiation hardness.
Detector currents measured at CiS and MPI (at 150V and 350V, normalized to 20 deg.). The acceptance criteria are indicated by arrows.
