【摘要】 报道辐射加热金等离子体Ｘ光发射时间特性。实验在星光Ｉ上进行，采用激光波长０．３５μｍ，能量（４０～６０）Ｊ，脉宽（６００～７００）ｐｓ的高斯型脉冲。实验采用双盘靶（Ａｕ－Ａｕ），两台软Ｘ射线能谱仪（ＳＸＲＥＳ）分别监测初、次级盘发射Ｘ光时间过程，两台谱仪采取时间关联记录。给出辐射加热金再发射Ｘ光时间特性，并分析、估算了膨胀等离子体空间发射Ｘ光的特性。更多还原

【Abstract】 Experimental study on the soft X ray reemission properties from gold material heated by X ray radiation produced by laser plasma is reported. Gaussian pulse of the Xingguang facility with wavelength 0.35 μm, energy (40￣60) J, pulse width (600￣700) ps is used. Primary and secondary emission of X ray are measured respectively with two soft X ray energy spectrometers (SXRES). Primary and secondary signalswere detected by time correlated record. X ray reemission properties from secondary disk (Au) heated by radiation of primary disk are given. The experimental results were analysed and discussed.更多还原
