ResumoA triple-focussing electron spectrum selector (TESS) is design. It is a non-dispersive (achromatic) magnet with intermediate double focussing. Electrons with a definite momentum range Δp/pπ50% are selected by proper slits at the intermediate double focussing plane, and are focussed triply (radial, axial and momentum coordinates) at a small cooled Si detector, where the energy is analyzed. It is used for studying conversion electrons following nuclear reactions. The background is extremely small. It can be used for measurements of angular distributions and transition times.
