MS—10质谱计控制器的改造

Modified C0ntroIIer of MS—10 Mass Spectrometer

摘要: A.E.I.MS—10质谱计控制器是一台电子管电路仪器。本工作采用集成电路代替加以改造,使新控制器获得了良好的稳定性。放大器的测量范围从10mV—10V扩大到10mV—100V,测量误差为±0.5％以内,适用于K—Ar和~(40)Ar—~(39)Ar定年。

Abstract: The controller of A. E. I. MS—10 mass spectrometer is an instrument using electronic tube circuit. It has been modified with an integrated circuit by the authors. The new controller has a good stability. Measurement range of the ampilifier is enlarged from 10mV—10V to 10mV—100V. The measurement error is within ±0.5％. It is table for K—At and ~(40)Ar/~(35)SAr age dating.
