✦ Synopsis

A new inner detector called Layer 0 has been added to the existing silicon detector for the DZero colliding beams experiment [V. M. Abazoz et al., Nucl. Instr. and Meth. A 565 (2006) 463]. This detector has an all carbon fiber support structure that employs thin copper clad Kapton sheets embedded in the surface of the carbon fiber structure to improve the grounding of the structure and a readout system that fully isolates the local detector ground from the rest of the detector. Initial measurements show efficiencies greater than 90% and 0.3 ADC count (240 e) common mode contribution to the signal noise. The total detector capacitance is 24 pF so this corresponds to 2 mV of common mode voltage.
