%X Water dimer (\textH<sub>2</sub>\textO)<sub>2</sub> - a vital component of the earth's atmosphere - is an important prototypical hydrogen-bonded system. It provides direct insight into fundamental chemical and biochemical processes, e.g., proton transfer and ionic supramolecular dynamics occurring in astro- and atmospheric chemistry. Exploiting a purified molecular beam of water dimer and multi-mass ion imaging, we report the simultaneous detection of all generated ion products of (\textH<sub>2</sub>\textO)<sup>+</sup><sub>2</sub>-fragmentation following single ionization. Detailed information about ion yields and reaction energetics of 13 ion-radical pathways, 6 of which are new, of (\textH<sub>2</sub>\textO)<sup>+</sup><sub>2</sub> are presented, including strong <sup>18</sup>\textO-isotope effects.
