FRONTIER ACCELERATOR TECHNOLOGIES

摘要

Although accelerator technology is more than a halfrncentury old, the application of new technologies isrnenabling continuing advances in performance andrncapabilities. These new capabilities as applied arerndriving advances in accelerator physics, condensedrnmatter physics, nuclear and atomic physics, molecularrnphysics, and even biological and medical research. Thernfield is as vital and growing today as it has ever been.rnExamples include ultra high gradient acceleration byrnlasers and wakefields for compact systems, advances inrnsuperconducting rf technology (single crystal niobiumrnand approaching theoretical gradient limits in high purityrnniobium) driven by the desires of the Next LinearrnCollider, high average current and high brightness inrnEnergy Recovering Linacs, two approaches to 4thrngeneration light sources, electron – ion colliders based onrnthe use of high collision frequencies and crab-crossing,rnspallation neutron generation, Muon factories andrnradioactive ion beams. Supporting technologies havernmade significant advances, too. RF generation by IOTsrnand solid state is growing in efficiency and powerrncapability. Photo injectors are producing high brightness,rnhigh average current and highly polarized beams at highrnreliability. This talk will present a survey of the mostrnadvanced accelerator programs and highlight some of thernexciting possibilities for the future..
