Abstract
A transition radiation detector that has been added to the NA31 CP violation experiment at CERN to improve the electron-pion separation is described. The detector consists of four radiators each followed by a proportional wire chamber. The wire chamber gas (Xe/CH/sub 4//He) has the same density as the CO/sub 2/ in the radiators to minimize the hydrostatic pressure difference. The gas gain of the chambers is stabilized online by monitoring with radioactive sources. A technique for electron-pion separation is discussed, and results obtained with test beams are given.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
