Beam tomography in two and four dimensions. [100 MeV H/sup +/ beams and 750 keV H/sup -/ beams]

Description: The coming generations of high beam-power accelerators require new techniques to monitor the emittance and the shape of the beam; in particular, measurements that do not interfere with the beam itself are necessary. A new computational algorithm, MENT (Maximum ENTropy), will be presented that combines nondestructive profile measurements taken from a number of stations along the beam line with beam-dynamics calculations to compute a four-dimensional phase-space distribution. A version of MENT ha… more

Four-dimensional beam tomography

Description: A computer code has been developed to reconstruct the 4-D transverse phase-space distribution of an accelerator beam from a set of linear profiles measured at different angles at three or more stations along the beam line. The code was applied to wire-scan data obtained on the low-intensity H/sup -/ beam of the LAMPF accelerator. A 4-D reconstruction was obtained from 10 wire-scan profiles; 2-D projections of the reconstruction agree fairly well with slit-and-collector measurements of the horiz… more

Maximum entropy Eddington factors. [Radiation hydrodynamics]

Description: A technique from statistical mechanics is applied to the problem of determining the most probable value of the Eddington tensor given the zeroth and first moment of the intensity. The result is applicable to two- and three-dimensional configurations and is intended for use in large radiation hydrodynamics calculations. 1 figure.
