摘要：

Using channeling in a 5-mm crystal with a bending angle of 1.5 mrad, a radical increase in the efficiency of beam extraction from accelerator was achieved due to an increased number of particle encounters with crystal. The measured world-highest efficiency of crystal extraction, over 40%, is in good agreement with theory predictions. The extracted beam intensity of 6 X 10(11) ppp was obtained, five orders of magnitude higher than previous results. (C) 1998 Published by Elsevier Science B.V. All rights reserved.
