  Curved crystals have been successfully used for a long time on the proton synchrotron U-70 of IHEP for the extraction of high-energy proton beams. With the beginning of the program for accelerating carbon ions at the U-70, crystalline deflectors of different lengths and different bending angles have also found application to provide experimental physical installations with ion beams. The report overviews recent results of activity in implementing crystal deflectors to extract proton and ion beams for the fixed-target experiments at the U-70 synchrotron of IHEP of National Research Centre "Kurchatov Institute".

Recently started studies on the application of volume reflection of particles in crystals for the steering beams (for extraction and collimation of a circulating beam in accelerators). Volume reflection is more efficient than channeling, but requires amplification of the deflection angle by applying multicrystals. The report discusses two new applications of multicrystals made like multistripe structures: 1. The property of effective deflection of particle beam was used to protect the septum-magnets of the U-70 in the process of extraction of the proton beam with energy of 50 GeV. 2. The possibility of generation of gamma radiation was studied in the secondary electron beam with energy of 7 GeV. In both cases, promising preliminary data were obtained.
