The "father" of microanalysis: Raymond Castaing, creator of a generation of scientific instruments, still in worldwide operation
Abstract
This manuscript emphasizes the leading role of Raymond Castaing in the conception, realization, and use of three major families of scientific instruments for local analysis of matter. Starting from his early studies with his research director, André Guinier, on the visualization of the GP zones in metal alloys, Raymond Castaing has introduced different stages of innovation for the identification of the elements present in the smallest volume of material. These were successively the X-ray electron probe, the secondary ion mass spectrometry with his student Georges Slodzian, the electron energy-loss filtering with his student Lucien Henry. Besides his Ph.D. dissertation, a reference text on any aspect of electron beam induced X-ray microanalysis, Raymond Castaing has continuously published, over a period of three decades, his research in the successive issues of the Comptes rendus de l'Académie des sciences
