The possibility to have Visitor Instruments at the VLTI has been granted to permit innovative observations by teams using stand-alone instruments, free from a substantial fraction of the requirements for fully automated VLTI general use instruments. In addition, the Visitor Instruments could provide a powerful scientific/technical test bench for new instrumental concepts, eventually to be incorporated later in VLTI facility instruments. ... a thorough technical description of the instrument, . ...

... The low energy plasma composition spectrometer AMEI-2 is built to be able to find in the low energy range of the phase space (E, q, j) and separate the fluxes of the major ion species in the magnetotail - H+, He++, He+ and O+, and analyse their energy and angular distributions. ... Electrostatic angular scanning in one direction and the use of the spin of the satellite to sample the other angle give the ability to measure 2-D distributions for each ion specie several times per spin. ...

Authors: Yu.G. Shevelev , V.A. Marsakov , . ... We have constructed and investigated properties of metallicity function of disk stars with different ages, proceeding from the statistically restored real altitude distributions of stars at the solar galactocentric distance. It is shown that the metallicity distribution of stars in each age range is not of Gaussian form, but it may be considered as a superposition of two normal distributions centered at -0.2 and 0.0 dex. ...
