Institut de Science Nucleaire, Grenoble
"For their critical leadership in conceiving and developing the electron cyclotron resonance (ECR) ion source and advanced ECR source, which have opened a new era in heavy ion studies of nuclear phenomena."
R. Geller was born in 1927. He received his undergraduate degree from the Conservatoires des Arts et Mitiers, Paris and his Doctorat en Sciences, under Prof. F. Perrin from Sorbonne University, Paris (1954). He was hired in 1948 by F. Joliot Curie at Commisariat ` l'Energie Atomique (CEA) and remained with CEA except for 1961-1962, when he worked as a research Associate at Stanford University, where he developed the first "Bumpy Torus Plasma".
Back in France he built several plasma devices based on electron cyclotron resonance (ECR) and he also taught a graduate course of controlled fusion.
Throughout the 1970's and 1980's he elaborated with his grenoble group the prototypes of ECR Ion Sources (ECRIS) for highly charge gaseous and metallic ions, and advocated theor utilization for new accelerator projects as well as for the existing cyclotrons, linacs and synchotrons... until their adoption for nuclear and particle physics and for hadrontherapy. After retirement from CEA (1992), he joined the Institut des Sciences Nucliaires, Grenoble, where he successfully developed a new ECR method called 1+ -> n+ which is a charge booster of radioactive ions of very short life times for ISOL-based systems. He also promotes a new high capacity ECR ion accumulator for pulsed machines. He has over 200 scientific publications including his book " ECR Ion Sources and ECR Plasmas " which provides a primer on these phenomena and their scaling laws.
In 1983 he received the " Prix Gegner of the Acadimie des Sciences Paris " and in 1987 the " Prix du CEA ".
