摘要： A unique facility for laser plasma physics and advanced accelerator research has recently been built at Tsinghua University. This system is based on a Tsinghua Thomson scattering X-ray source （TTX）, which combines an ultrafast TW laser with a synchronized 45 MeV high brightness linac. In our recent laser wakefield acceleration experiments, we have obtained 10-40 MeV high quality monoenergetic electron beams by running the laser at 5 TW peak power. Under certain conditions a very low relative energy spread of a few percent can be achieved. Absolute charge calibration for three different scintillating screens has also been performed using the linac system. 其他題名： Chinese Physica C 出版日期： 2015 出處： Chinese physics C, 2015, Vol.39 (1), p.70-76 資源來源： Institute of Physics Journals 識別號： ISSN: 1674-1137 識別號： EISSN: 0254-3052 識別號： DOI: 10.1088/1674-1137/39/1/017001
