一种测量金属原子束密度通量及空间分布的新方法

为测量激光原子法同位素分离中密度通量 ,采用两端镀有铜电极的玻璃基片作测量探头 ,通过检测蒸镀在玻璃基片上两电极间金属薄膜电阻的变化来测量密度通量。探头输出信号经由多路 A/ D数据采集卡处理后送入微型电子计算机 ,经计算处理可实时给出密度通量的空间分布。实验结果表明 ,该方法费用低、精度高

New method for the measurement of vaporized metal atomic flux distribution

A new method is presented to measure the atomic flux for atomic vapor laser isotope separation. The detector was made of glass slabs with copper electrodes coated on their ends. The atomic flux was measured by monitoring the resistance change between the coated films. The output signal from the detector was then digitized and monitored in real time. Several detectors in beam cross section with a multi-channel A/D converter, were used to measure the atomic flux distribution in a real time. The experimental results show the method has advantages in both cost and accurate.
