A Forward Proton Detector at DØ

Gilvan A. Alves

DØ Collaboration

March 17, 1998

Abstract:

The addition of a Forward Proton Detector (FPD) as a new sub-detector of the DØ detector for Run II is discussed. This document describes the physics motivation for the FPD as well as its location and performance.
