小能量0.35μm激光-X射线转换研究
Study of X-Ray Conversion from Disk Targets Irradiated by 0.35 μm Laser at Low Energies
摘要
以小能量0.35μm激光(<100 J)辐照盘靶(Φ600μm×4μm),用软X射线平响应探测器测量X射线角分布(dE/dΩ)和X射线转换效率(ηx)。dE/dΩ=a+bcosθ,与角无关。ηx随激光入射角增加而下降。按金盘、多层膜(0.11μm)金盘和CH膜(0.4μm)金盘顺序,ηx依次下降。
Abstract
Abstract We have measured the X-ray angular distribution (dE/dΩ) and X-ray conversion (ηx) from a disk targets (Φ600μm×4μm) irradiated by 0.35 μm laser (<100 J) with soft X-ray flat-response detector.dE/dΩ=a+bcosθis independent ofangles.ηxdecreaseds with the increasing laser incident angles with respect to the target normal.ηxalso decreaseds when Au disk is replaced by multilayer film (0.11μm)+Au disk or CHfilm (0.4μm)+Au disk.
