Phys. Rev. ST Accel. Beams 7, 100101 (2004) [6 pages]Low-beam-loss design of a compact, high-current deuteron radio frequency quadrupole accelerator
C. Zhang1,2 *, Z. Y. Guo1, A. Schempp2, R. A. Jameson2, J. E. Chen1, and J. X. Fang1 Received 15 September 2004; published 26 October 2004 A 201.5 MHz, 50 mA, 2.0 MeV deuteron radio frequency quadrupole accelerator is proposed as the neutron generator for the neutron experiment facility project at Peking University, China. Based on better understanding of beam losses, some new optimization procedures concerning both longitudinal and transverse dynamics are adopted. Accordingly, the beam transmission efficiency is improved from 91.2% to 98.3% and the electrode length is shortened from 2.91 to 2.71 m. The fundamental physical analyses are performed to look inside the new design recipe and explain why it works. ©2004 The American Physical Society
