cost, using conservative efficiency assumptions, is$4.70 to $6.30/bbl, depending on grade and heating rate. At steady state,
co-produced gas can generate more than half the electric power needed for the process, with the fraction depending on oil shale
grade. This would increase production to 7.3 x 10 (exp 5) bbl/day for 104 l/Mg shale and 1.6 x 10(exp 6) bbl/day for 146 l/Mg
shale using a combination of off-peak power and power from co-produced gas.

Effects of Radiation Induced carbon Contamination on the Performance of an EUV Lithographic Optic
Barty, A.; Goldberg, K. A.; Mar. 2003; In English
Report No.(s): DE2003-15004704; UCRL-JC-151235; No Copyright; Avail: National Technical Information Service (NTIS)
Carbon deposition in extreme ultraviolet lithography (EUVL) is known to occur when optical surfaces in a hydrocarbon
environment are exposed to EUV light. Carbon contamination on EUV optical elements affects both the absorption and phase
of the reflected light. Because the carbon deposition alters the phase structure of the reflected EUV light it effectively alters
the figure of these optics and, thus, the aberrations as well. Absorption by deposited carbon not only reduces throughput but
also leads to apodisation of the pupil, which in turn affects imaging performance.

Development of Superconducting Focusing Quadrupoles for Heavy Ion Drivers
Martovetsky, N. N.; Manahan, R.; Lietzke, A. F.; Sep. 20, 2001; In English
Report No.(s): DE2003-15004701; UCRL-JC-145352; No Copyright; Avail: National Technical Information Service (NTIS)
Heavy Ion Fusion (HIF) is exploring a promising path to a practical inertial-confinement fusion reactor. The associated
heavy ion driver will require a large number of focusing quadrupole magnets. A concept for a superconducting quadrupole
array, using many simple racetrack coils, was developed at LLNL. Two, single-bore quadrupole prototypes of the same design,
with distinctly different conductor, were designed, built, and tested. Both prototypes reached their short sample currents with
little or no training. Magnet design, and test results, are presented and discussed.

Systematic Uncertainties on (delta)M2 from Neutrino Physics, using Calorimetric Energy Reconstruction
Harris, D. A.; Aug. 2003; In English
Report No.(s): DE2003-812828; FERMILAB-CONF-03/216-E; No Copyright; Avail: National Technical Information Service
(NTIS)
This report describes how uncertainties in neutrino interactions, particularly at neutrino energies of a few GeV, can
contribute to uncertainties in measurements of neutrino oscillation parameters for experiments using calorimetric devices.
Uncertainties studied include those on final state multiplicities, cross sections, electron-hadron calorimeter differences, and
nuclear rescattering.
