The innermost layer (L00) of the Run IIa silicon detector of CDF
was planned to be replaced for the high luminosity Tevatron upgrade of Run
IIb. This new silicon layer (L0) is designed to be a radiation tolerant
replacement for the otherwise very similar L00 from Run IIa. The data are
read out via long, fine-pitch, low-mass cables allowing the hybrids with the
chips to sit at higher z (approximately 70 cm), outside of the tracking
volume. The design and first results from the prototyping phase are
presented. Special focus is placed on the amount and the structure of
induced noise as well as signal to noise values.
