Quadrupole scans were used to characterize the LEDA RFQ beam. Experimental data were fit to computer simulation models for the rms beam size. The codes were found to be inadequate in accurately reproducing details of the wire scanner data. When this discrepancy is resolved, we plan to fit using all the data in wire scanner profiles, not just the rms values, using a 3-D nonlinear code.
Maximally Smooth Functions (MSFs) are a form of constrained functions in which there no inflection points or zero crossings high order derivatives. Consequently, they have applications to signal recovery experiments where signals interest expected be non-smooth features masked by larger smooth foregrounds. They can also act as powerful tool for diagnosing the presence systematics. The nature MS...
A radioactive ion beam of 6He produced via the 7Li(p,2p)6He reaction with typical intensity of 3 × 106 ions/see was elastically scattered from LiF(Au) targets. Elastic scattering of 6He at Elab=27 MeV with 197Au have been measured in the angular range of 6º-72º in the laboratory system employing LEDA and LAMP detection system. Optical Model calculations have been used to fit the data .
The Lyon-Meudon Extragalactic database (LEDA) gives a free access to the main astrophysical parameters for more than 100,000 galaxies. The most common names are compiled allowing users to recover quickly any galaxy. All these measured astrophysical parameters are first reduced to a common system according to well defined reduction formulae leading to mean homogeneized parameters. Further, these...
Within the last decade, a number of libraries of data structures and algorithms have become available for object-oriented languages. In some cases, like the Smalltalk class library [7], the Java base classes [2], and the C++ Standard Template Library [3], the libraries come as part of the programming enviroment. In addition to this, many third party libraries of data structures and algorithms e...
