Abstract

The results of the numerical and experimental investigations of the beam RF capture in the booster – fast-cycling proton synchrotron are presented in this report. The existing features of the magnetic field cycle of the accelerator are taken into account in the simulation. The time dependence of the RF voltage as well as the moment of the beam injection (during the field cycle) have been optimized to get the maximum efficiency of the capture. The experimental results giving nearly 100% beam cap¬ture in the Booster are presented.

Abstract

Light ion acceleration program is being pursued in IHEP, Protvino. Light ion beams are planned to be used both for fundamental and applied research. Currently, the scope of activity extends over an ion source, the 100 MeV Alvarez linac I100, new beam transfer line from I100 to the 1.3 GeV rapid-cycled Booster proton synchrotron U1.5, beam injection system, and the U1.5 machine itself. In the first run of 2008, 3∙10¹⁰ deuterons were successfully accelerated up to 450 MeV/u and extracted to an external beam absorber. The report outlines technical milestone passed, up-to-date status of these works and experimental results achieved.
