摘要：

Measurements from balanced or slightly unbalanced, double-null, ELMing H-mode plasmas show that the upper, more closed, divertor strike point particle fluxes are larger than the lower, more open, divertor strike point particle fluxes for comparable conditions. Comparison of the upper and lower outer strike, point peak particle fluxes measured with Langmuir probes during scans of the magnetic balance shows an. asymmetry around the magnetic balance point which is consistent with both the enhanced upper recycling and the expected direction of private region E x B drifts. Comparison of the inner and outer peak particle fluxes in the upper divertor shows a dependence on magnetic field direction that is also consistent with the private region E x B drift direction.
