Formation and interaction of low-energy electrons and biomolecular ions in electrostatic storage ring

The interaction between delta electrons and DNA molecules and other biological structures is one of the important processes taking place in hadron therapy. This paper discusses the formation of low-energy electrons and ions of DNA molecules and other biomolecular ions in an electrostatic storage ring. The results of experimental studies into the interaction between electrons and biomolecular ions for a simulation of the contribution that delta electrons make to the radiation damage of cells in hadron therapy are presented.
