Since the resolution of a detector is limited by the statistics of the number of produced free charge carriers, a detector with a small minimal ionization energy per free charge is most favorable. The thousand times smaller gap of a superconductor (order of meV) compared to a semiconductor detector (Δeff(Si) = 2.94 eV, Δeff(Ge) = 3.6 eV)1 offers the possibility for particle detectors with an improved energy resolution2, 3, 4.
