• Vlasov equilibria of a periodic array of axisymmetric double cusp plasmas arestudied numerically for various values of fi (ratio of the maximum plasma pressureto the maximum magnetic pressure at midplane of the double cusp vessel).Effects of finite Larmor radius, ambipolar potential and presence of cold plasmacomponent are taken into account. It is shown that the plasma volume expandsas 73 increases, forming a clear transition layer between plasma and vacuumwith thickness of the order of the local ion Larmor radius in the high-/? case.The stored energy in a single vessle increases rapidly with 73. A strong ambipolarpotential is formed either in the line cusp region or in the point cusp region,depending on the boundary conditions, and plasma expands radially in thecentral region. Cold electrons are gathered in the central region by the ambipolarpotential, but the hot plasma component is little affected by the potential.
