Abstract
A new type of mass spectrograph with large mass dispersion has been constructed. The distinguishing feature of this apparatus is that the mass dispersing action of a r-l magnetic field is utilized. The instrument has a r-1 magnetic field of 198.1° sector type (22 cm mean radius) as the dispersing field, a toroidal electric field of 118.7° sector type (30 cm mean radius) and a 30° uniform magnetic field (120 cm mean radius) as the focusing fields. The principle, the design and important parts of the apparatus are described. The dispersion on the photographic plate was estimated to be 14 cm for 1% mass difference and the maximum resolving power of about 500,000 was obtained.
