Abstract
The results on the extraction of a proton beam of a varying intensity from the U-70 accelerator using bent silicon single crystals are presented. Stable beam extraction using crystals has been demonstrated for two experiments where smooth adjustment of the beam intensity over a large dynamic range has been required.
