Paper Abstract

The use of high energy particles to do imaging was proposed first in 1946 by R. WILSON but it is only during the last decade that various ways were considered and tried. They relied mostly on the following mechanisms : variations of the particle range due to variations in density objects using various beams (alphas and neons in BERKELEY, protons in LOS ALAMOS, variations of the proton beam intensity distribution near the edge of materials created by the Multiple Coulomb Scattering effect (HARWELL). These two methods are based on the electromagnetic interaction and measures at one time, one projection. To obtain tomographic information like in the X-ray scanner, one has to repeat the measurements under a considerable number of angles. In 1975, a third method, the nuclear scattering radiography (N.S.R.) was introduced at C.E.R.N. : it relies to strong nuclear interaction and measures directly the density inside elementary volumes, without any relative motion of the beam and the object.
