Studying a Mode of Intense Proton Beam Extraction by a Bent Crystal with Simultaneous Operation with Internal Targets on the U-70 IHEP Accelerator

A method for extracting a proton beam from the U-70 IHEP synchrotron using a bent silicon crystal at a simultaneous operation of several internal targets is described. The optimal range of the crystal bending angles is 0.5–2.5 mrad, and the crystal length along the beam is 2–5 mm. The extracted-beam intensity can be varied from 107 to 6.0 × 1011 protons per cycle of the U-70 operation, depending on the requirements of physical experimental installations. The method developed for the accelerated-beam extraction with the use of short crystals significantly extends the possibilities of conducting physical experiments on the accelerator.
