The radiation emission of highly charged ions imersed into dense matter is of great interest for basic science and applications, e.g. for atomic physics in complex environments (non-ideal dense plasmas, solids, strong fields) and the interaction of heavy ion beams with matter (stopping power, inertial fusion). Rapidly growing interest at GSI in related novel experiments is supported by the kilojoule laser project PHELIX and the future accelerator developments. We report about the first successful experiments pointing in these future directions. By means of two dimensional curved X-ray crystal technique we have managed to observe a) heavy ion projectile radiation of H- and He-like argon ions inside solid matter, b) three electron autoionizing states in hollow ions populated by a highly dense plasma environment (i.e. in classical low density atomic physics experiments related line transitions cannot be observed) produced by the nhelix-laser [1], c) observation of two electron inner-shell transitions from autoionizing states of highly charged ions in large scale dense nhelix-laser produced plasmas [2].
