N1  - We thank the COSY staff for the successful operation of COSY with its injector cyclotron and polarized ion source. We are grateful to E. D. Courant, Ya. S. Derbenev, D. Eversheim, G. Fidecaro, W. Haeberli, H. Huang, Yu. F. Orlov, H. Rohdjea, T. Roser, H. Sato, W. Scobel, E. J. Stephenson, K. Ulbrich, K. Yonehara, and others for their help and advice. This research was supported by grants from the German BMBF Science Ministry, its FFE program at COSY, and the Helmholtz Association through funds provided to the virtual institute "Spin and strong QCD'' (VH-VI-231).
AB  - We recently tested a new spin resonance crossing technique, Kondratenko Crossing (KC), by sweeping an rf-solenoid's frequency through an rf-induced spin resonance with both the KC and traditional fast crossing (FC) patterns. Using both rf bunched and unbunched 1.85 GeV/c polarized deuterons stored in COSY, we varied the parameters of both crossing patterns. Compared to FC with the same crossing speed, KC reduced the depolarization by measured factors of 4.7 +/- 0.3 and 19(-5)(+12) for unbunched and bunched beams, respectively. This clearly showed the large potential benefit of Kondratenko Crossing over fast crossing.
