Little is known about biological radiation action on the molecular level. Experiments with small biomolecules in the gas phase have the advantage of studying ionization and fragmentation dynamics in finite systems but are less realistic radiation damage models. To be able to investigate more complex biomolecular systems, such as peptides and proteins, we have developed a new apparatus in which a home built electrospray source can be interfaced with a low energy (keV) ion beamline or different photon beamlines (e.g. of synchrotrons or free electron lasers). First spectra of peptides obtained with this set-up will be presented. Dependencies on energy of the radiation as well as peptide length and structure will be thereby discussed.
