摘要：

Toward the study of the free-radicals behavior, we have proposed a production method of a short-pulsed beam, based on a bunch rotation after momentum cooling. The method was experimentally investigated at the HIMAC synchrotron. In the experiment, after the momentum spread was cooled down to around 0.02% at FWHM through electron cooling, an RF-field was non-adiabatically applied. Under an intensity of (3-7) x 10(6) argon-ions and an RF amplitude of 340 V, a short-pulsed beam with the duration of 30-35 ns at FWHM was obtained after a quarter period of the synchrotron oscillation.
