Double ionization of helium exposed to intense Ti:sapphire 800 nm laser light

HECToR的全部能力将通过专家级人工使用成熟且获奖的HPC代码HELIUM来有效和高效地使用，以解决暴露于800 nm钛宝石基本波长的高强度激光的氦原子。在1.5 x 10^14 W/cm ^2至6.0 x 10^14 W/cm ^2的重要范围内，以0.5 x 10^14 W/cm ^2的间隔，在10个单独的激光峰值强度下计算能量分辨双电离产额。这样的计算将是第一个钛：蓝宝石基本波长（800 nm），其中大多数实验工作集中，并通过补充精确的实验测量领域产生重大影响。根据氦的早期使用情况（这也确定了拟议计算的可行性），我们估计这项工作将在2008年1月至6月期间使用3000万AU的HECToR。

The full capability of HECToR will be effectively and efficiently employed through in-hand expert man-power usage of the well-established and prize-winning HPC code HELIUM in addressing the helium atom exposed to high-intensity laser light at the Ti:sapphire fundamental wavelength of 800 nm. Energy-resolved double ionization yields will be calculated at ten separate laser peak intensities at intervals of 0.5 x 10^14 W/cm^2 over the important range 1.5 x 10^14 W/cm^2 to 6.0 x 10^14 W/cm^2 inclusive. Such calculations will be the first for the Ti:sapphire fundamental wavelength (800 nm) where most experimental work is concentrated and through complementing precise experimental measurement have a major impact on the field. Based on early-time usage of HELIUM (which has also established the feasibility of the proposed calculations) we estimate that this work will use 30 million AUs on HECToR over the period January to June 2008.
