※ 引述《iskandar (東京銘粿御滿幸最中)》之銘言： : http://www.researchgate.net/profile/Hai_En_Tsai/publications : Hai-En Tsai : University of Texas at Austin · Department of Physics : Article: Compact tunable Compton x-ray source from laser-plasma : accelerator and plasma mirror : ABSTRACT: We present results of the first tunable Compton back- : scattering (CBS) x-ray source that is based on the easily : aligned combination of a laser-plasma accelerator (LPA) and a : plasma mirror (PM). The LPA is driven in the blowout regime by : 30 TW, 30 fs laser pulses, and produces high-quality, tunable, : quasi-monoenergetic electron beams. A thin plastic film near : the gas jet exit efficiently retro-reflects the LPA driving : pulse with relativistic intensity into oncoming electrons to : produce 2×107 CBS x-ray photons per shot with 10-20 mrad : angular divergence and 50 % (FWHM) energy spread without : detectable bremsstrahlung background. The x-ray central energy : is tuned from 75 KeV to 200 KeV by tuning the LPA e-beam central : energy. Particle-in-cell simulations of the LPA, the drive : pulse/PM interaction and CBS agree well with measurements. : arXiv. 11/2014; arXiv:1411.2134v2. : ====== : 有朝一日蔡海恩接到瑞典皇家學會的電話通知 : 濁水溪公社的人就要團結起來幹你娘農友看不懂英文啦 http://ndltd.ncl.edu.tw/cgi-bin/gs32/gsweb.cgi/ccd=ANYIVs/searchresult_mobile_ bj http://ndltd.ncl.edu.tw/cgi-bin/gs32/gsweb.cgi/ccd=ZjSzVt/record?r1=1&h1=0 -- ※ 發信站: 批踢踢實業坊(ptt.cc), 來自: 61.230.207.200 ※ 文章網址: http://www.ptt.cc/bbs/LTK/M.1416889925.A.060.html
