We describe the basic structure and the making process of radiation-sensitive image-converter-tubes ; these tubes are self-sensitive for 10 kev to 10 Mev photons or cold and thermal neutrons. In most general use, these tubes have an affective field aperture of 22 or 30 cm but it is also possible to make smaller (15cm) or larger (40cm) tubes. Data and application characteristics of these tubes are given. The conversion factor (the output image luminance corresponding to a given input radiation) is high enough to allow the real-time acquisition of the image, like with a T.V. camera or a high speed camera for example. Typical conversion factor are 100 cd.m-2.mR-1.s for X-rays and 3.10-10 Cd.s.n-1 for neutrons. The spatial resolution is 2.5 to 5 1p.mm-1 depending of the kind of the tube ; density steps of 2 % are detected. Applications of these tubes are illustrated by examples in medicine (cine-angiography and televised-surgery) as well as in ballistics.
