Stopping powers are relevant to a wide range of applications, spanning materials sciences, culturalheritage, medical applications, fission and fusion technologies and space applications. They are directlyused in experimental techniques such as ion beam analysis, deposition ranges, ion implantation, andstudies of radiation damage, to name a few. Reliable values of stopping powers are also needed inisotope production and detector development for basic and applied research. In this work we give anoverview of the last twenty years of experimental effort, identify the trends in recent measurements [1-5], and discuss the emerging data needs. Our analysis is based on the comprehensive experimentalelectronic stopping power database of the International Atomic Energy Agency [6,7], and on selectedsemi-empirical and theoretical descriptions. We also present the recent effort to modernize the IAEAstopping power database and create a versatile tool adaptable to the needs of a continuously developinguser community.
