The strip of the two layers of each pair will be roated by 90 to determine the (x,y) coordinates of the electron impact point with spatial resolution of the order of 200 um. The hodoscope will be formed by plastic scintillator tiles, coupled to Silicon Photomultipliers via Wavelength Shifting Fibers. These technologies allowed to develop a compact design for a high performance detector system. The FT will detect electrons in the angular and energy ranges of 2.5-4.5 and 0.5-4.5 GeV, respectively, at the nominal luminosity of the CLAS12 spectrometer of 1035cm-2s-1. The new equipment will operate in magnetic field and high-radiation environment due to the proximity with the beamline. The expected energy resolution is of ~ 2.5% for 1-GeV electrons. The Forward Tagger project involves an international collaboration including Universities and Research Institutes of four nations, as INFN, IPN-Orsay (France), CEA-Saclay (France), the University of Edinburgh (UK), the James Madison University (USA), the Norfolk State University (USA), the Ohio University (USA) and Jefferson Lab. Financial contribution for the design and construction of the detector have been provided by INFN, the UK Research Council, the US Department of Energy and National Science foundation and the European Union.The Forward Tagger is presently in the construction phase and will be installed at Jefferson Lab in the Fall of 2015.
