Latest addition : 9 July 2018.

Japet is a 2 MV Tandem Pelletron (6SDH-2, National Electrostatics Corp.) equipped with an external SNICS-II ion source (negative ions by cesium sputtering) which can deliver electronegative ions such as Cl, I, C, Si, V, Cu, Zr, Ag, Au… This system is capable to produce energies of 0.5 to 4.0 MeV for single-charged ions, up to 6 MeV for double-charged ions, and correspondingly higher energies for ions of higher charge states. The SNICS-II source is naturally very efficient for halogen ions: chlorine and iodine. Yields for Cu, Au and Al are excellent. Si ions are also abundant. Ni, Ti and Zr ion beams have a quite satisfactory flux, but hardly above 14 MeV, 10 MeV and 12 MeV respectively. Weaker V, Ag and Nb beams can also be produced. Maximal current at target is for example 50 µA for protons, 1.5 µA for Au4+, 1.3 µA for Al3+, 18 µA for Si3+ or 4.3 µA for Ni2+.
