摘要
围绕北京医用质子同步加速器的方案，研究设计了１／３整数共振的慢引出系统。利用该系统，可获得较高的引出效率（大于９５％）、较小的引出束流发射度（在静电切割器处，积分发射度为０．１５πｍｍｍｒａｄ）、较窄的引出动量分散（０．
A third order beam extraction scheme for the conceptual design of Beijing proton therapy synchrotron is presented in this paper.Using the scheme,an extraction of beam with higher efficiency(above 95%),smaller emittance(0 15πmm·mrad of time integrated emittance at the electrostatic septum),narrower momentum spread(0 12%) and more uniform intensity can be obtained.
