Abstract: This review summarizes the present status of an ongoing experimental effortto provide reliable rate coefficients for dielectronic recombination of highlycharged iron ions for the modeling of astrophysical and other plasmas. Theexperimental work has been carried out over more than a decade at the heavy-ionstorage-ring TSR of the Max-Planck-Institute for Nuclear Physics in Heidelberg,Germany. The experimental and data reduction procedures are outlined. The roleof previously disregarded processes such as fine-structure core excitations andtrielectronic recombination is highlighted. Plasma rate coefficients fordielectronic recombination of Fe^q+ ions q=7-10, 13-22 and Ni^25+ arepresented graphically and in a simple parameterized form allowing for easy usein plasma modeling codes. It is concluded that storage-ring experiments arepresently the only source for reliable low-temperature dielectronicrecombination rate-coefficients of complex ions.
