The JLab12 group at the Laboratori Nazionali di Frascati (LNF) aims for a detailed understanding of nucleonstructure in terms of novel parton distribution functions that provide remarkable tomographic images of quarks and gluons inside the nucleon. The mapping of these new functions, the so-called GPDs (Generalized Parton Distributions) and TMDs (Transverse Momentum Dependent) distributions, is a major focus of the hadron physics community and constitutes a milestone in the physics program of Jefferson Lab at 12 GeV. Our group is involved with leading participation in various different experiments for studying GPDs and TMDs with CLAS12 (Hall B), which are already [link approved] or in preparation. A main focus of the group's activity is the project of a large size RICH (Ring Imaging CHerenkov) detector that will significantly enhance the CLAS12 hadron identification capabilities. The LNF JLab12 group consists of 5 senior researchers and 4 post-docs and young researchers which collaborate in a very vivid atmosphere for the various projects of the group. Our research activities are supported by laboratories for detector development and a well equipped computing centre with its participation in the GRID network. The LNF JLab12 group works in close collaboration with the Universities of Rome "Sapienza" and the University of Rome "Tor Vergata" provides a very vivid environment for the formation of students and young researchers.
