DESIGN OF SLOW EXTRACTION FOR A SMALL PROTON THERAPY SYNCHROTRON
-
Abstract
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.
