• Analytic expression for the longitudinal adiabatic invariant is derived for generalmagnetic configuration. The orbit loss is evaluated to determine the outermost loss-free surface. Geometrical factor of the neoclassical transport coefficients in 1 / vregime in helical torus is calculated by using the longitudinal adiabatic invariant. Thedependence of the particle confinement upon the geometrical parameter is in-vestigated; and the improvement by the inward shift of the plasma is quantitativelyclarified.[adiabatic invariant, particle loss, helical torus, LHS, neoclassical transport, Ul numerical calculation, stellaratorl
