Detector Engineering Drawings

Engineering drawings for all detectors are available as postscript files as listed below. (typically 450kbytes each).

20 December 2000: Following recently agreed design changes, these drawings have been modified as follows:

- All detector drawings: Version number is 003.

- All detectors: 4 edge pads (top-left, top-right, bottom-left, bottom-right) have been removed.

- Wedge detectors: edge pads running along the top and bottom have been removed.

- W12 is re-dimensioned such that its inner radius is increased by 13mm (to allow pixel detector insertion).

- The Alignment and ID marks are unchanged (version 002)

Available drawings:

In A4 size:

• Forward wedge 12
• Forward wedge 21
• Forward wedge 22
• Forward wedge 31
• Forward wedge 32
• Alignment and ID marks
• Barrel detector

In A3 size:

• Forward wedge 12
• Forward wedge 21
• Forward wedge 22
• Forward wedge 31
• Forward wedge 32
• Alignment and ID marks
• Barrel detector

To Version 001: (between 3rd. August and 5 November 1999):

17 Aug.99: W12 ac probe pad size increased to 80x50 micron.

28 Oct.99: Fid.Mark B metal width re-dimensioned to 30 micron (was 15).

4 Nov.99: Fid.Mark C spacing error (was 25) corrected to 50 micron.

8 Nov.1999: All drawings were updated to: Version 002, 5 Nov. 1999

Fiducial mark A: centre to cross-hair gap increased to 20 micron. In addition to modifying the drawing `Alignment and ID marks' the wedge detector custom stereo marks were re-dimensioned on drawings W21,W22,W31,W32. W12 was not directly affected.

10 Nov.99:

Barrel detector: the stereo centre mark was re-drawn, in line with changes to mark A.

Alignment and ID marks: mark B now fully dimensioned.
