    Abstract

    DIAM (Dispositif d'Irradiation d'Agrégats Moléculaires) is a new experimental setup devoted to investigate processes induced by irradiation at the nanoscale. The DIAM apparatus is based on a combination of techniques including a particle beam from high-energy physics, a cluster source from molecular and cluster physics, and mass spectrometry form analytical sciences. In this paper, we will describe the first part of the DIAM apparatus that consists of an ExB double spectrometer connected to a cluster ion source based on a continuous supersonic expansion in the presence of ionizing electrons. This setup produces high intensities of energy-and-mass selected molecular cluster ion beams (1000 s of counts s -1). The performance of the instrument will be shown through measurements of 6-8 keV beams of protonated water clusters, (H 2O) nH + (n = 0-21) and mixed protonated (or deprotonated) water-pyridine cluster ions: PyrH +(H 2O) n (n = 0-15), Pyr 2H + (H 2O) n (n = 0-9), and (Pyr-H) + (H 2O).
