Query: Track Extrapolation and Distribution for the CDF-II Trigger System   The CDF-II experiment is a multipurpose detector designed to study a wide
range of processes observed in the high energy proton-antiproton collisions
produced by the Fermilab Tevatron. With event rates greater than 1MHz, the
CDF-II trigger system is crucial for selecting interesting events for
subsequent analysis. This document provides an overview of the Track
Extrapolation System (XTRP), a component of the CDF-II trigger system. The XTRP
is a fully digital system that is utilized in the track-based selection of high
momentum lepton and heavy flavor signatures. The design of the XTRP system
includes five different custom boards utilizing discrete and FPGA technology
residing in a single VME crate. We describe the design, construction,
commissioning and operation of this system.
