穆斯堡尔谱仪主要由振动子和驱动电路两大部分组成。驱动线路用来驱动振动子和控制谱仪的工作,振动子的驱动线圈和拾波线圈安放在磁钢系统的磁隙中,用弹簧片支撑。当参考信号为三角波时,振动子就按等加速度方式运动,其频率为7.03Hz。它是由115.2kHz石英晶体振荡器经两块7级二进制分频产生,在振动子上装有穆斯堡尔放射源~(57)Co,谱仪工作时,放射源~(57)Co放出的γ射线受到了振子振动速度的调制,在振子振动的周期内,不同时刻的速度值随时间线性增加。
Mossbauer spectrometer mainly by the vibrator and drive circuit composed of two parts. The driving circuit is used to drive the vibrator and control the spectrometer. The driving coil and the pickup coil of the vibrator are placed in the magnetic gap of the magnet system and supported by the spring plate. When the reference signal is a triangular wave, the vibrator moves at an equal acceleration and its frequency is 7.03Hz. It is produced by two 7-stage binary frequency demultiplexing by a quartz crystal oscillator of 115.2 kHz with a Mossbauer radioactive source ~ (57) Co on the vibrator. When the spectrometer is in operation, the radioactive source ~ (57) Co emits The γ-ray is modulated by the vibration speed of the vibrator. During the vibration of the vibrator, the velocity values increase linearly with time at different times.
