Particle and heat fluxes at the upper X-point region in JET ohmic and auxiliary heated discharges are deduced from the experimental CCD camera and magnetic measurements. Modelling of the particle and heat transport processes at the edge of the plasma by Monte Carlo orbit-following calculations agrees well with the observations. The importance of the finite orbit effects in low collisionality plasmas is assessed. It is found that the convection by plasma ions plays a very important role in the heat transport from the plasma to the wall.
