AbstractHigh power pulse xenon lamp is the core unit of inertial confinement fusion (ICF),whose luminous efficacy affects the output efficiency of ICF directly. The lamp transmittance is an important factor for the degradation of luminous efficacy. When high power pulse xenon lamp runs different shots, the transmittance of composite quartz tube will degrade. In this study, the middle of the composite quartz tubes was selected when the lamps run 0 shot, 88 shots, 2000 shots, 3000 shots, 5000 shots and 8000 shots, and the spectral transmittances of these samples were tested and compared. The transmittance has no longer a significant degradation when the xenon lamp runs 88 ~ 8000 shots. In order to find the reason for the degradation of the transmittance, the composite quartz tubes (middle tubes and the tubes closed to the cathode portion) of the xenon lamp that runs 0 shot and 2000 shot are selected, and then they are tested by the transmittance,X ray diffraction, fluorescence and component analysis. The testing results show that there is no crystal precipitation in composite quartz tube when the xenon lamp is running, so the degradation of the transmittance is not caused by the crystal precipitation; the valence change of cerium ion from cerium doped layer may be one reason for the degradation of the transmittance, the other reason is many impurities on the lamp tube from electrode.

Other Abstract大功率脉冲氙灯是惯性约束聚变(ICF)装置的核心器件,它的光效直接影响ICF的输出效率,氙灯灯管的透过率是氙灯光效下降的重要原因。在大功率脉冲氙灯运行不同发次后,复合石英灯管透过率会下降。实验选取了脉冲氙灯放电0发次、88发次、2000发次、3000发次、5000发次、8000发次后的复合石英管中部,对这些样品进行光谱透过率测试并加以对比,发现灯管的透过率在88发次到8000发次就趋于稳定,不再明显下降。为找到复合石英灯管透过率下降的原因,特选取放电试验0发次和2000发次的复合石英灯管(灯管中部和靠近阴
