Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
In the fast ignition realization experiment project phase-I (FIREX-I) [H. Azechi and the FIREX Project, Plasma Phys. Control. Fusion 48, B267 (2006)], core heating up to an ion temperature of 5 keV is expected for subignition-class carbon-deuterium (CD) and deuterium-tritium (DT) fuels. The dependence of the achieved ion temperature on heating pulse parameters, and core density is investigated using two-dimensional simulations. Since the core size in FIREX-I is insufficient for self-ignition, and the confinement time is comparable to the heating duration (∼10 ps), the temperature relaxation between the bulk electrons and ions is important for efficient ion heating. High compression (a core density of ρ >200 g cm3) is required for pure DT fuel to shorten the relaxation time. In this case, a heating energy of Eh >2 kJ and a duration of τh <10 ps are required to achieve an ion temperature of 5 keV. For CD and DT+foam fuels, the requirement for implosion is relaxed since the relaxation is fast, due to a large effective charge; 5 keV ion heating is achieved at ρ 50 g cm3 with Eh >2 kJ and τh ∼10 ps. © 2008 American Institute of Physics.
