Abstract:
The efficiency of the extraction of a beam from an accelerator is radically improved owing to the application of short crystals of length up to $1.8$ mm bent through a small angle of about $1$ mrad. This success is due to an increase in the multiplicity of particle transmission through the crystal used. A record efficiency of the extraction of $70$ GeV protons in excess of $80\%$ is achieved experimentally, this result being in agreement with theoretical predictions. It is shown that the crystal can efficiently operate at the injection energy of $1.3$ GeV.
