※ 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 뜠Department 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 2휱07 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其實以前古早時代的背死郭佩宜也在兩千年出頭回來台灣成為人類學家惹似乎較鮮為人知因為她玩時還在肛門欲時期前 http://www.ioe.sinica.edu.tw/Content/Researcher/content.aspx?&SiteID=530167135 246736660&MenuID=530167136406372131&Fid=0&MSID=530210534050522147 http://guavanthropology.tw/article/1491 加入濁水溪讓你思路變清晰做研究寫論文當農友有求必應 -- ※ 發信站: 批踢踢實業坊(ptt.cc), 來自: 223.137.228.158 ※ 文章網址: http://www.ptt.cc/bbs/LTK/M.1418644079.A.E0B.html ※ 編輯: ppc2t2 (223.137.228.158), 12/15/2014 19:50:41
