Abstract
The new results of using short (2-4mm) bent crystals for extraction and collimation of proton beam at IHEP 70 Gev proton synchrotron are reported. A broad range of energies from 6 to 65 GeV has been studied in the same crystal collimation set-up where earlier the extraction efficiency of 85% was obtained for 70 GeV protons using a 2-mm Si crystal. The new regime of extraction is applied now at the accelerator to deliver the beam for different experimental setups within the range of intensity 10E7-10E12pppFile in questo prodotto:
