【摘要】 采用OMA-2系统,测定了脉宽为3微秒的脉冲氙灯在2200～8800(?)波段的光谱分布和光谱效率。 研究了不同放电电压、不同充气压力对脉冲灯光谱输出的影响。结果表明,随放电电压和充氙压力的增加,脉冲氙灯的紫外光谱效率从13％增加到17％左右,紫外总辐射能量也显著提高。更多还原

【Abstract】 By using OMA-2 system (Optical Multichannel Analyzer), the spectral distribution and UV spectral effeeiency in 2200 to 8800 A region of a flash-lamp with a pulse width (FWHM) of about 3 /LIS have been measured. Only four pulses are required for making each measurement.The influence of variation of discharge voltage and the gas pressure of the flash-lamp on its spectral distribution has been investigated. The UV spectral efficiency is increased from 13% to 17% with the increasing of discharge voltage and gas pressure. The total UV emission energy also increases appreciably.更多还原
