National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Abstract	Quadrupole scans were used to characterize the transverse beam of the LEDA RFQ. The original scan data, obtained when the HEBT was installed immediately downstream of the RFQ, were reanalyzed by fitting to the 3-D nonlinear simulation code IMPACT. All the data in the measured profiles at the wire scanner were used not just the rms widths. The measured and simulated profiles still have differences in their shapes that have not been explained. An improved model is required to get better fits and may result in more accurate emittance measurements.
