Abstract
The feasibility of extracting protons from the halo of a high energy b eam by means of a bent silicon crystal has been investigated. Protons diffusing from a 120 GeV beam circulating in the SPS at CERN have been extracted at an angle of 8.5 mrad. Efficiencies of about 10 percent, orders of magnitude higher than the values achieved previously, have b een measured. The present results are promising in view of beam extrac tion from future multi-TeV proton accelerators.
