  1. G.Bashindzhagyan Moscow State University June 2002 Si/W CALORIMETER CONCEPT 1. The Mechanical Structure. Possible types of module Stainless steel plate ~1 m The Module Elektronics …….. Si/W layers ~1 m Internal structure (not in scale). Stainless steel plate ~10 mm Tungsten plates 1.4 - 4.2 mm Spacers glued to W • Spacers. • ~500 mm long; • material: steel(?), titanium (?). ~0.3 mm ~3 mm 50 mm 50 mm ~0.2 mm 2.5 mm

  2. G.Bashindzhagyan Moscow State University June 2002 Si/W CALORIMETER CONCEPT 2. Detector Board. • Top View. • Length: ~50 cm; • Width: 5/6/10 cm; • Pixel size: 1-2 cm2. Detector Board G10 (?) 0.2 mm 0.1 mm 0.1 mm Pixeled Si detectors Cross section (not in scale). Gold strip-lines on the kapton cable Kapton cable Elastic foam band ~2.5 mm Detector Board Silicon detectors

  3. G.Bashindzhagyan Moscow State University June 2002 Si/W CALORIMETER CONCEPT Compare to regular wire bonding: • three contacts; • a protection is required. • The strip-line bonding: • only one contact; • no additional thickness. 3. Kapton Cable • Kapton thickness ~20 µm; • Gold strip-line thickness ~10 µm; • Gold strip-lines width ~100 µm; - The Detector Board (G10 ?); - Kapton layer; - Gold strip-line on the kapton; - Silicon sensors; - Elastic foam band. Top View. ~ 2 mm 5 (6;10) cm Gold strip-lines The holes in the kapton Kapton cable Detector Board iside the Module. Cross section.

  4. G.Bashindzhagyan Moscow State University June 2002 Si/W CALORIMETER CONCEPT 4. Silicon Detector. First option: One detector 1010cm2 size. Second Option: Four detectors 55cm2 size. A coast per 1 cm2 can be essentially less for the second option. ~10 cm ~10 cm 6” Si-Wafer Possible types of Si-detectors: Strip detector (type 1). Pixel detector. Detector size: 55 cm2; Pixel size: 1.251.25 cm2; Pixel area: 1.251.25=1.56 cm2; Number of pixels: 16. Detector size: 55 cm2; Strip width: 0.31cm; Strip area: 50.31=1.56 cm2; Number of strips: 16. Strips of both detectors connected to one strip-line on the kapton cable forming one 10cm long strip. Each detector size: 55 cm2; Area of two connected strips: 1.55 cm2; Number of strips: 32. Strip detector (type 2). Detector #1 Detector #2
