HIRFL-CSR主环慢引出设计
Design of slow extraction for HIRFL-CSR main ring
-
摘要: 对HIRFL-CSR工程的主环（CSRm）的共振慢引出进行了设计，并采用Winagile程序对引出过程进行了初步的计算机模拟。主环慢引出采用幅度和动量选择引出机制，其引出通道和快引出通道相同。采用了1/3整数共振慢引出机制来获得约1 s的较均匀的引出束流，该引出束流的水平发射度小于1 πmm·mrad。Abstract: The slow extraction of beam from CSR main ring(CSRm) is designed and simply simulated by Winagile program in this paper. The amplitude-momentum selection scheme is used, and both fast and slow extraction will be arranged in the same extraction passage. The third integer resonant scheme is adopted in slow extraction to obtain extracted beam with a horizontal emittance less than 1 πmm·mrad in about 1 second.
