Abstract

PURPOSE:To enhance the sensitivity of a mass spectrometer by restricting both the angle of each part and the ratio of the dimension of each part of the spectrometer within a given range. CONSTITUTION:Concentric double toroidal electrodes A and B deflect an ionic beam at an approximately right angle. An ionic beam discharged from these electrodes A and B is further deflected by a deflection magnetic field at an approximately right angle. The angle of each part, and the ratio of the dimension of each part of a mass spectrometer are restricted within the following ranges. 0.9<=re/rm<=1.2, 0.8<=RE1/re<=2.0, 0.5<=RE2/re1.2, 32 deg.<=Ep1<=36 deg., -10 deg.<= Ep2<=-8 deg., 0.9rm<=le' <=1.2rm, 0.4re/Re 0.6. Ionic beams to and from the deflection magnetic field are both oblique to the field.
