Double tunnel junctions Sn--I--Sn--I--Sn are investigated. An inhomogeneous state of the Sn film, which arises due to the appearance of a second energy gap in addition to the primary one, is obtained in the regime of a narrow quasiparticle source (the voltage on the injector V/sub g/approx. =2..delta../e). The size of the gaps, which are related to the nonuniform state, decreases in a weak magnetic field. This result is explained by the decay of the constant component of the oscillatory Josephson current and by the replacement of the Josephson tunneling current at V/sub g/ = 2..delta../e by a quasiparticle current, which increases the density of nonequilibrium quasiparticles.
