Adaptive Particle Management (APM) method originally developped by Assous is improved for cylindrical 2-dimensional Particle-In-Cell code with 2nd-order shape function. Charge, momentum and energy for overall particles and charge and current density on each grid are rigorously conserved during particle refinements. In order to minimize the deformation of velocity distribution function, phase-space resampling of refinement particles was introduced. We tested our new code in Counter-Helicity
