On this photograph the silicon strip detectors (dark squares) can be seen
mounted on a pc board. Of the 256 strips/detector, only the central 32
channels are read out. Kapton cables (gold color) are wirebonded at the
silicon, and wirebonded at the other end to a small daughter board, which sits
on the large mother board. The large grey ribbons on the back of the mother
board connect to the Heap Manager board (not visible). A cover box, consisting
of 6mm foam with Al foil on both sides, is removed in this picture. It mounts
to the bottom plate with the white edge. A heavier, metal box fits over the
foam one, and rests on the heavy metal bottom plate. These boxes are
electrically isolated shields.
The volume in which the silicon sits can be temperature-controlled (see the
plexi cylinders). The temperature of the volume in which the electronics sit
can controlled independent of the silicon temperature.
