Power positron beams for High Energy Density physics
In this talk I will discuss the modern theoretical developments and review today situation in power positron beams research, including physical and technical aspects of generation and absorption of the positron beams with GeV particle energy and about (0.01–0.1) A beam current, positive “charge pumping” process, with emphasis on suggestions for some HED (High Energy Density) physics applications: (1) macroparticle accelerator, (2) proton and heavy ion intermediate energy accelerator and (3) soft(about few MeV energy range) gaser. I will also describe the physics and conceptual design of the machines (1)–(3).
Prospects for a gamma‐ray laser
Lasers generating wavelengths shorter than one angstrom unit would have many important applications. Ever since the discovery of the Mossbauer effect it has been realized that we would be able to stimulate nuclear transitions suitable for lasers in this range if we could prepare the population inversion on which lasers depend, and it has also long been known that some nuclear isomers are producible in a state of population inversion. Why then do we not yet have any operating gamma‐ray lasers?
A 70‐Mev Synchrotron
A synchrotron for the production of 70‐Mev x‐rays has been built and tested. The general mode of operation, and various features of its design and construction, are discussed. Some preliminary information on the characteristics of the electron and x‐ray beams is included. This work has been supported by the Office of Naval Research.
