The magnetic limiter and helical divertor geometry predicted by vacuum magnetic field calculations has been confirmed by measurements with various probe and calorimeter arrays in Heliotron-E. The effect of modification of these configurations with auxiliary magnetic fields or a material limiter on the edge plasma profile is studied. The relation of the edge plasma properties with the main plasma parameters (density, heating power, etc.) are described. The amount of total heat loss to the divertor region is almost the same as that of the heating power. The edge plasma density is approximately proportional to the core plasma density.
