Abstract
The resolving power of a long magnetic lens using a field that rises linearly from a zero value at the source and becomes constant at a distance z0 has been calculated as a function of z0 for two emission angles 26.5° and 31°. For z0 smaller than the radius of the spectrometer the resolving power remains nearly equal to that of a uniform field lens and then deteriorates quickly for values of z0 greater than the radius of the spectrometer. The first‐order spherical aberrations as well as the location of the ring focus and the detector are given graphically as functions of z0.Keywords
