Non resonant slow extraction of protons from the IHEP accelerator to the SWD setup

70 GeV proton beam of the intensity of 108 ppc with the high quality time structure is required for physical experiments with the SWD spectrometer on a beam line from the IHEP accelerator. The proton beam extraction to the SWD has to be done by a deflection to beam line 22 by bent crystal of a part of the beam, which is extracted to beam line 8 during a resonant slow extraction. Results of setting-up the extracting mode and the main characteristics of the extracted beam are given. (R.P.) 9 refs.; 3 figs.; 1 tab
