| Zusammenfassung: | The properties corresponding to the addition of a convergent toroidal magnetic lens between the source and the solenoidal field of an electron-guide are calculated and experimentally tested on a non-optimized present system. The conditions necessary to fully exploit this original association are deduced from this first implementation. It is possible to obtain an improved efficiency on a large energy range, together with a large β
+ rejection and an increase of the solid angle freed for a complementary γ-detection. |
