Abstract
A TMGe detector designed for high-energy tomography has been successfully tested on a 100-Hz pulsed X-ray beam produced by a 8-MeV linear accelerator. A dynamic range of five decades has been measured, corresponding to 25-cm lead attenuation, with a maximum dose rate of 0.43 rad/s. The ratio between the electronic pulse current and the ionic interpulse current, mostly dependent on the duty cycle, was improved by means of electronics integrating during the pulse and just before. TMGe has been demonstrated to be an interesting detecting medium for fan-beam tomography, where a large number of very homogeneous, high-dynamic-range cells is required.<>
