Our studies led to the Pegase project, founded by NSF (Grant CHE-0750377) and installed in TAMU, which allows a 130 KV acceleration of NPs delivered by a LMIS source (Liquid Metal Ion Source). The Pegase instrument is working with success since one year and a half. The first results presented during this conference demonstrate the interest of this new probe for the biological and also nano-structured surface analysis. The Pegase project allowed the design of new more ambitious instruments taking into account the results obtained at higher energies in the MeV range [2] named ANDROMEDA and END-MS (Environmental Nano domain-mass Spectrometry). The differences between the two projects are the energy, respectively 4 MV and 1 MV and the framework respectively national facility and university facility. At the beginning of this year, Andromeda has won the national call for proposal EQUIPEX (Excellence Equipment) and the realization is starting. The goal and therefore the heart of the two projects are the same: The goal is to create a new instrument for the analysis by mass spectrometry of nanofields and nano-objects present on a surface with a spatial resolution of ~100 nm. This instrument is also meant for the surface analysis at the ambient pressure and therefore the mass spectrometry analysis on native hydrated biological surfaces. Molecular information (mass and structure) will be obtained from the impact of a Nano-Particle accelerated in the MeV range by a Van de Graaff electrostatic accelerator from 1 to 4 MV. The principal devices of the new instrument are a rising generation of ion sources NAPIS (NAno Particle Ion Source), the accelerator and the localization of the impacts of NPs to reach nanometre dimensions; this last point was developed by the TAMU group[3]. The dedicated instruments installed will be a ToF mass spectrometer with high mass resolution, and finally the bombardment at the quasi-ambient pressure associated to an effective analysis by mass spectrometry. We shall recall the main results leading to the new projects. The projects will be described and the first results concerning the source R&D in progress will be presented: metallic nanodroplet beam provided by a commercial FIB (Focussed Ion Beam) column COBRA X from OrsayPhysics and preparation of the new NAno-Particles Ion Source (NAPIS).

ANDROMEDE The goal of Andromeda is to create a new instrument for the analysis by mass spectrometry of nano-fields and nano-objects present on a surface with a spatial resolution of ~ 500 nm. Moreover this instrument will permit the surface analysis at the ambient pressure and therefore the mass spectrometry analysis of native hydrated biological surfaces. This project is a very efficient alternative to the Secondary Ion Mass Spectrometry, SIMS. Molecular information (mass and structure) will be obtained starting from the impact of a Nano-Particle accelerated in the MeV field by a Van De Graaff electrostatic accelerator from 1 to 4 MV 4
