Technological Innovation on the Stable Magnetism of VG354 Mass Spectrometer and Its Significance
This paper describes the method and way for the stable magnetism of VG354 mass spectrometer. Hall probe is fixed by technological innovation so that the magnetism can be stabilized . Sr and Nd isotopic ratio are mormalized to 86Sr/88Sr=0.1194 and 146Nd/144Nd =0.7219. The 87Sr/86Sr (NBS987)=0.710228±10(n=24).The 146Nd/144Nd (La Jolla) =0.511860±6(n=9).
