Abstract
A long lens beta-ray spectrometer with a pure “triangular” field is here investigated theoretically. A point source as well as a disk source is considered. It is shown that the effect of the source width on the resolution is much smaller with this field than with a uniform field. The spherical aberration is rather large, but the maximum luminosity at a given resolution is larger than with a uniform field. The results are in agreement with experiments.
