Biphasic Hydroformylation of Higher Olefins with Redox-Switchable Surfactants

65647 Recent advances in high frequency linear accelerator technology have resulted in steady-state electron beams having RF bunch widths of 50 to 200 femtoseconds, considerably shorter than the practical resolution of fast diagnostic streak camera systems. Therefore, the accurate measurement of the longitudinal phase space of ultra short bunches using microwave power would be highly advantageous and economically attractive, especially if the complexity, sensitivity, and a priori assumptions associated with alternative electro-optic methods could be avoided. This project will develop a high gradient, circularly polarized, beam deflecting microwave structure that provides a highly amplified image display with the electron bunch phase and energy distributions projected in orthogonally differentiated azimuthal and radial directions. Combining such a higher-order mode structure with a beam focusing element offers a simple on-line diagnostic for the definitive measurement of ultra short RF bunches. In Phase I, a detailed microwave and beam optics analysis of the proposed RF bunch diagnostic system will be performed, and hardware design specifications will be established. Commercial Applications And Other Benefits as described by the awardee: The technology should result in an on-line beam monitoring system capable of accurately evaluating the RF bunch performance of advanced accelerator systems. The attainment of very short RF bunches should be of considerable interest for free electron lasers, wakefield accelerators, linear colliders, and the generation of intense coherent radiation
