  The determination of scalar leptons and gauginos masses is an important part
of the program of spectroscopic studies of Supersymmetry at a high energy
linear collider. In this talk we present results of a study of pair produced
Scalar Electrons, Scalar Muons and Scalar Neutrinos searches in a
Supersymmetric scenario at 3 TeV at CLIC. We present the performances on the
lepton energy resolution and report the expected accuracies on the production
cross sections and on the scalar leptons and gauginos masses.
