On using bent single crystals for proton extraction from IHEP accelerator

The multiturn extraction of protons for physical experiments is realized. The crystal deflector is installed in the vacuum chamber of U-70. The simultaneous extraction of the accelerated protons using bent single crystals and secondaries from internal targets on the flat top of the magnetic cycle is ensured. The results of proton beam extraction in a common mode with the extraction of secondaries are given. The use of bent single crystals at the IHEP accelerator is considered.<>
