Abstract:	摘要： Using quadrupole scan measurements we show laser-wakefield accelerated electrons to have a normalized transverse emittance of 0.21−0.02+0.01πmmmrad at 245 MeV. We demonstrate a multishot and a single-shot method, the mean emittance values for both methods agree well. A simple model of the beam dynamics in the plasma density downramp at the accelerator exit matches the source size and divergence values inferred from the measurement. In the energy range of 245 to 300 MeV the normalized emittance remains constant. 出版者： College Park: American Physical Society (APS) 出版日期： 2012-11-05 出處： Physical Review Special Topics - Accelerators and Beams, 2012-11, Vol.15 (11), p.111302, Article 111302 資源來源： American Physical Society Journals 版權： 2012.
