Abstract:

The fast and slow control of the Central Silicon Tracker in H1 is performed by means of an ASIC decoder chip having four digital input lines. These control signals as well as the analog hit signals are transmitted to and from the detector through 34 m of optical fibers, which are composed of three connectable multifiber cables.
