Abstract

We demonstrate a time-of-flight electron energy analyzer that operates at an 80 MHz repetition rate. The analyzer yields an energy resolution of 40 meV for 3 eV electrons. The energy resolution limit is dominated by the detector time (or temporal) resolution. With a currently available detector with a temporal resolution of 100 ps, we predict an energy resolution of less than 1 meV for 200 meV electrons. This makes high repetition rate time-of-flight energy analyzers a promising low-technology alternative to current state-of-the-art techniques.
