摘要
描述穆斯堡尔谱仪系统原理、结构、驱动机制 ,对探测器的选择与 14.4 ke V能量窗口的甄别、放射源匀加速运动、驱动波形与同步问题进行了分析 ,指出谱仪使用和调整时应注意的问题 ,并就其对穆斯堡尔谱精确测量的影响进行了探讨 .
A description of the Mssbauer system principle, structure, driving mechanism is presented, and the detector selection, the discrimination of 14.4keV γ-ray energy-window, the uniform accelerated motion of radioactive source, driving waveform and synchronization are analyzed. The problems in using and adjusting the Mssbauer spectrograph system are proposed, and their influence on the accurate measurement of ME spectrum is discussed.
