随着穆斯鲍尔谱学研究和应用工作的发展,要求谱仪具有高质量、多功能的特性,我们研制成的绝对定标等速驱动谱仪是在等加速谱仪的基础上,扩大了“等速驱动”和“激光测速”两个功能。在提高谱仪的性能,尤其是线性指标方面也取得了一些经验。 等速谱仪与等加速谱仪相比,有其突出的优点:它可以把驱动速度调节在所需要的范围内作较高精度的测量,例如在共振峰位处监测计数率随温度的变化,以很高的精度测量相变点。在穆斯鲍尔双共振、极化效应和无反冲因子测量等方面,它也是必不可少的手段。
With the development of Mussel Bauer spectroscopy research and application, it is required that the spectrometer has the characteristics of high quality and multi-function. The absolute calibration isokinetic spectrometer we developed is based on the equal acceleration spectrometer A “speed drive” and “laser speed” two functions. Some experience has also been gained in improving the performance of the spectrometer, especially the linear index. Isokinetic spectroscopy and isochronous spectroscopy compared to its outstanding advantages: it can drive the speed adjustment in the required range for more accurate measurements, such as the resonant peak in the monitoring of the count rate with temperature changes , Measure the phase change point with high precision. It is also an indispensable tool in Muspass birefringence, polarization effects and non-recoil factor measurements.
