摘要：

A new class of X-ray imaging gaseous detectors was developed, based on photon conversion in a thin film and the detection of the emitted secondary electrons with a low-pressure avalanche wire chamber. Their main features are parallax-free imaging with a submillimeter spatial resolution over a broad range of X-ray energies, a nanosecond response and a counting rate capability above 1 MHz/mm(2). The imaging characteristics of a large area secondary electron emission (SEE) detector equipped with CsI, Ag and Ta photoconvertors, in the photon energy range of 6-60 keV are summarized. In localization capability this detector can successfully compete with commercial image intensifier systems and medical film-screen combinations.
