Abstract :
Summary form only given. Measurements have been made on 4-mm-diameter gas proportional straw tubes with lengths up to 1 m, operating with a gas mixture tailored for both efficient X-ray detection and high-rate operation. Using a new high-bandwidth shaping amplifier, which has an impulse response of about 3.5 ns full width at half maximum (FWHM), a clear picture of signal reflections from the end of anode wire has been obtained. Electronic noise levels resulting from the various modes of anode wire termination, and the lowest signal levels that can be used to satisfy high-rate operation and efficient particle or transition radiation photon detection have been determined.<>
