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).
Power positron beams as a new branch of beaming research
Some of the most desirable problems in modern physics are impossible to solve at the current stage of technical and technological development. So, the main role today should belong to theoretical research aimed at new, innovative approaches and solutions. Theory must answer the question on whether such problems have a potential solution, and if so, what experimental directions need to be developed first, and to what extent.
A slowly rotating coil system for AC field measurements of Fermilab Booster correctors
A method for measurement of rapidly changing magnetic fields has been developed and applied to the testing of new room temperature corrector packages designed for the Fermilab Booster Synchrotron. The method is based on fast digitization of a slowly rotating tangential coil probe, with analysis combining the measured coil voltages across a set of successive magnet current cycles. This paper presents results on the field quality measured for the normal and skew dipole, quadrupole, and sextupole elements in several of these corrector packages.
