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.

Hector的全部能力将被有效和高效地利用，通过手把手的专家人力使用久负盛名的获奖HPC代码氦来处理暴露在800 nm钛蓝宝石基本波长的高强度激光下的氦原子。能量分辨双电离产额将在1.5×10~(14)W/cm~2至6.0×10~(14)W/cm~2的重要范围内，在0.5×10~(14)W/cm~2的10个不同的激光峰值强度下进行计算。这将是第一次对钛宝石基频波长(800 Nm)进行这样的计算，因为大部分实验工作都集中在这里，并且通过补充精确的实验测量对该领域产生了重大影响。根据氦的早期使用(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月期间在赫克托上使用3000万个澳大利亚元。
