Description

The CDF Run-II silicon microstrip detector has witnessed 12 fb-1 of proton-antiproton collisions over the last 10 years. It has shown remarkable performance, with 90% of its channels functional, 80% error-free, and only one of its eight layers near the operational limits for full depletion. The measured bias currents, depletion voltage and signal-to-noise ratio of these sensors provide unique information about the behavior of sensors irradiated slowly over a long period of time. Charge collection measurements from irradiated, double-sided sensors reveal a doubly-peaked electric field inside the sensors that is weaker in the center and stronger at the edges.
