  The determination of the smuon mass at the CLIC multi-TeV e+e- linear
collider has been studied for two CMSSM benchmarks. Results are given for both
the analysis of the muon energy spectrum and the threshold scan method. The
effects of detector resolution, beam-beam interactions and accelerator- induced
backgrounds are discussed. The energy spectrum technique is also applied to the
\~t -> t ~g process to determine the scalar top mass, in scenarios with the
gluino lighter than the squarks.
