SUSY Parameters from Charginos
  The chargino pair production processes at $e^+e^-$ collisions are explored to reconstruct the fundamental SUSY parameters: the SU(2) gaugino parameter $M_2$, the higgsino mass parameter $\mu$ and $\tan\beta$. Both CP-conserving and CP-violating SUSY sectors are discussed.
