	The facility for modification and analysis of materials with ion beams (FAMA) is the low energy part of the TESLA Accelerator Installation, in the Vinča Institute of Nuclear Sciences, Belgrade, Serbia. It presently comprises two machines: a heavy ion source (M1) and a light ion source (M2), and two experimental channels: a channel for analysis of ion beams (C1) and a channel for surface modification of materials (C2). In April 2009 the Vinča Institute signed a contract with the Joint Institute for Nuclear Research, Dubna, Russia, on the upgrading of FAMA. The contract comprises: (i) the refurbishment of the M1 and M2 machines and the C1 and C2 channels, (ii) the construction of a channel for ion implantation (C3) and a channel for deeper modification of materials (C4), (iii) the construction of a small isochronous cyclotron (M3), and (iv) the construction of a channel for analysis of materials in vacuum (C5) and a channel for analysis of materials in air (C6). This presentation is devoted to the upgraded FAMA and its research program.
