During solar flares a large number of charged particles are accelerated to high energies, but the exact mechanism responsible for this is still unclear. Acceleration in collapsing magnetic traps is one of the mechanisms proposed. We consider analytic ideal kinematic MHD models for collapsing magnetic traps. Particle orbits are calculated using the guiding centre approximation. A couple of examples of a collapsing magnetic trap models will be presented together with some of the effects of the initial conditions of the particles on the trapping times and particle energy gains.
