Viktor Leonidovich Kashevarov, Yuri Andreevich Usov "Investigation of polarization effects at accelerators in Mainz and Bonn using a polarized target created at DLNP JINR"

The Mainz Microtron MAMI and the electron accelerator ELSA in Bonn are the main world facilities for investigations of meson photoproduction reactions on nucleons. In recent years, the facilities have been updated by a frozen spin target designed in DLNP JINR. It allows significantly expanding the set of experimentally measured polarization observables. The report gives an overview of recent experiments at MAMI and ELSA with the Dubna-Mainz frozen spin target. Future plans are also presented.
