【摘要】 利用机械泵和涡轮分子泵为核心组成的发光屏动态测试系统,只需40 min左右就可获得1×10-4Pa的真空度。由于电子枪采用了LaB6阴极,可暴露于大气;并且利用光纤传输光信号,连接到单色仪,信号经处理后送到微机完成光谱的自动测试。最后给出了YAG投影管用荧光粉的测试光谱。更多还原

【Abstract】 A novel automatic testing system has been successfully developed for the purposes of in-situ evaluating and monitoring the phosphor coating of the luminance screen. The main features of the system include the adoption of mechanical and molecular pumps to ensure fast pumping, usage of oxidation resistant LaB6 cathode in electron gun and data transmission optical fiber, which transmits the signals to a host PC computer for automatic data analysis. The typical spectra of the phosphor of the yttrium aluminum garnet (YAG)projection tube are given.更多还原
