The time-frame of this proposal coincides with the preparation phase of new experiments in hadron physics (PANDA, CBM, CLAS12, KLOE2, SIDDHARTA-2, AMADEUS) and the upgrade phase of running experiments (COMPASS,ALICE). Most of these experiments deal with the selection of rare probes in high multiplicity environment at collision rates of up to 107 events/sec. Therefore fast, high granularity and radiation hard detectors for electron as well as hadron identification, high resolution secondary vertex determination and high speed event-selection and data acquisition systems have to be developed. Gaseous or solid targets for (un)polarized protons and light nuclei play a very essential role in experiments at MAMI,
ELSA, COSY, JLAB and CERN and will be of great relevance also for FAIR. Experiments with polarized antiprotons would increase the physics potential of FAIR substantially. The ongoing R&D activities along these lines have to be continued in order to maximally exploit the present accelerator facilities like GSI, LNF, MAMI, COSY, ELSA and CERN in Europe or non-European laboratories like JLab and J-PARC and the high intensity beams envisaged at the future FAIR facility for the CBM and PANDA experiments.

The structure of the JRAs of the present project guarantees the interplay between experiment and theory which plays a crucial role in hadron physics field. The interconnections between the JRA-projects are detailed in the attached diagram (Figure below).
The HadronPhysics3 project will improve the performance of the European Research Infrastructures, and will help to maintain their leading role in hadron physics worldwide. The Joint Research Activities will provide the most advanced instrumentation existing in the home laboratory of each participating group or in transnational access centers, concentrate highlevel expertise at such research infrastructures, and strengthen their scientific cooperation with the European Universities and Research Centres guaranteeing a high degree of synergy for the challenging tasks and common targets to be achieved. Scientists from Europe and outside will participate in forefront research performed at the accelerator facilities MAMI in Mainz (Germany), DAFNE in Frascati (Italy), COSY in Juelich (Germany), GSI in Darmstadt (Germany), CERN in Geneva (Switzerland), ELSA in Bonn (Germany), JLab (USA) and J-PARC (Japan).
