Far Forward Tracking for the ILC

Mission statement: This document is an attempt to answer several important questions regarding tracking in the very forward region of a future ILC detector. It is a "working document"; the current status of several ongoing Monte Carlo simulation studies is reviewed. The document will be updated regularly, and should reach its definitive shape - a complete review of the tracking requirements for the very forward region - by the end of 2007.

The discussion is organized in a series of articles. After some introductory remarks, in two articles the reader is reminded of some aspects of the physics requirements of the ILC experiments, the layout of the detector concepts and some of the candidate detector technologies. Finally, the software tools used in this study are briefly presented.

Some of the assumptions in the Technology section require a better foundation. A more detailed analysis of the applicability of the various technologies is provided in this page . As the discussion is still at a very premature stage, this page is locked with a password.

The experimental environment of a linear e+ e- is very clean compared to today's hadron colliders. Nevertheless, machine-induced backgrounds cannot be ignored. In this section, the hit densities in the forward tracker due to beamstrahlung pair background is discussed.

In the articles below the tracking performance in the forward region is discussed in detail. In each article a separate aspect is discussed in detail.

This final article summarizes and merges the findings of the individual studies.
