Abstract
A transition radiation detector to identify electrons at 90% efficienc y with a rejection factor against pions of 10(3) on an area of 2.85 x 2.85 m(2) has been constructed for the NOMAD experiment. Each of its 9 modules includes a 315 plastic foil radiator and a detector plane of 176 vertical straw tubes filled with a xenon-methane gas mixture. Deta ils of the design, construction and operation of the detector are give n. (C) 1998 Elsevier Science B.V. All rights reserved.
