Abundances of the elements in the solar system

A review of the abundances and condensation temperatures of the elements and their nuclides in the solar nebula and in chondritic meteorites. Abundances of the elements in some neighboring stars are also discussed.Comment: 42 pages, 11 tables, 8 figures, chapter, In Landolt- B\"ornstein, New Series, Vol. VI/4B, Chap. 4.4, J.E.

Potential for deep natural gas resources in eastern Gulf of Mexico

The main purpose of the research is to evaluate the geological possibility that significant economically recoverable resources of natural gas exist in sedimentary basins of the United States at depths greater than 150,000 ft. While relatively unexplored, these gas resources may be large. The main objectives of the research are to determine the geologic factors that control deep gas accumulations in addition to the distribution and resource potential of these accumulations

Transverse envelope dynamics of a 28.5 GeV electron beam in a long plasma

The transverse dynamics of a 28.5 GeV electron beam propagating in a 1.4 m long, 0-2 x 10^14 cm^-3 plasma are studied experimentally in the underdense or blow-out regime. The transverse component of the wake field excited by the short electron bunch focuses the bunch, which experiences multiple betatron oscillations as the plasma density is increased. The spot size variations are observed using optical transition radiation and Cherenkov radiation. In this regime, the behavoir of the spot size as a function of the plasma density is well described by a simple beam envelope model. Dynamic changes of the beam envelope are observed by time resolving the Cherenkov light
