The thermal conductivity of the layered s-wave superconductor NbSe 2 was measured down to Tc/100 throughout the vortex state. With increasing field, we identify two regimes: one with localized states at fields very near Hc1 and one with highly delocalized quasiparticle excitations at higher fields. The two associated length scales are most naturally explained as multi-band superconductivity, with distinct small and large superconducting gaps on different sheets of the Fermi surface.
