Abstract

An experimental demonstration confirming the beam dynamics of a ramped-gradient drift-tube linac (RGDTL) was performed at Los Alamos National Laboratory. The RGDTL was designed to meet the requirements of maximum beam acceleration, minimum longitudinal and transverse emittance growth, and acceptable wall power loss. At low beam energies, transverse-magnet focusing is weak and the RF defocusing must be minimized. As the beam energy increases, stronger RF defocusing can be tolerated and the RF electric field gradient can increase. A detailed comparison of theory and experiment was carried out. Experimental data and theory were in good agreement.<>
