“…The combined response of filters, mirror and XRD produces a narrow spectral range with a well defined cutoff at the edge energy for the low energy channels, whereas for the higher energies the response rises at energies > 5 keV. The signal from each channel is timed with an electrical fiducial pulse that is referenced to the timing of the laser pulse, obtaining a sinchronisation better than 200 ps [119,120,121,122].…”

“…After the implosion experiment, the ' Al activity can be ?4 counted for 5 minutes and then the remr. ming Na activity can be 9 4 counted for 24 hours. A second counting of the ' Na produces the target fraction which is collected allowing the determination of the 28 Al activity produced in the SiO ?…”

Inertial confinement fusion is the present and future source of energy in our universe. Derivatives, such as solar, geothermal, wind, and biomass are proposed as future substitutes for possible fuel sources. All of these possible sources of energy while they may be considered to be renewable do not fulfill the single most important criteria of being unlimited. Fuel reserves of more than 100 billion years are accepted as " unlimited". The understanding of fusion has many "fathers", Bethe, Teller and many others, it has also had proponents (too many to list) as the world's energy supply. This author hopes that this Program's efforts will contribute positively to the advance to the time when fusion energy will positively contribute to the energy supply for mankind. Controlled fusion is judged by us to be the world's most challenging technological problem. The potential benefit to mankind of an unlimited source of energy and thus a higher standard of living make the acceptance of this challenge worth our while. There are many dedicated scientists working on controlled fusion to make this dream a reality. Magnetic and inertial fusion are in a horse race that must not be allowed to falter or to be cancelled. Fusion is the future of the world and one of these approaches to fusion is vital to our future generations

“…1,2 Spectrometers currently in use for such measurements employ either K-filter vacuum x-ray diodes ͑XRD͒ or K-; L-edged filter total outer reflection ͑TOR͒ mirror-XRD sets. 3,4 A significant disadvantage of the first recording scheme is the presence of stray contributions to recorded signals from x-ray quanta with energy exceeding the K-edge filter absorption energy. 5 The disadvantage of the second scheme is the impossibility of using TOR mirrors at photon energy greater than 0.5 keV.…”
