The completely detached high confinement (CDH) regime established recently in high power ASDEX-Upgrade single null divertor discharges is described. The standard CDH mode scenario with feedback controlled external deuterium and neon puffing is analysedin detail with respect to its divertor detachment and confinement properties. Impurity transport and pumping effects and the density operation window of the CDH mode are outlined. First results with other impurity radiators (N, Ar) are given.Finally the CDH mode operation space is discussed in terms of main chamber and scrapeoff layer plus divertor radiation and possible consequences for future fusion experiments are outlined.
