In a recent study, the Canadian Academy of Engineers has made several recommendations concerning the pursuit of clean energy pathways for Canada's future. One of these recommendations is that Canada re-establish a research program to pursue fusion energy which is the ultimate abundant and clean energy source for mankind. The current proposal is a critical step towards establishing a Canadian research effort in Inertial Fusion Energy (IFE) focused on the pursuit of promising new advanced ignition concepts. These concepts are fast ignition and shock ignition where either an ultrashort (20 picosecond) laser pulse acts as match to trigger the ignition of the fusion reactions or an intense uniform pulse (200-500ps) launches a shock wave to create an ignition temperature spike in a compressed fuel pellet. Both techniques could reduce the size of the overall laser system by at least a factor of two having a significant impact in accelerating the development cycle for a fusion reactor system. Currently the world is awaiting breakthrough results from the 2 Megajoule laser system at the National Ignition Facility at Lawrence Livermore National Laboratory (LLNL) which should demonstrate the feasibility of laser fusion using the traditional self ignition scheme within the next 6 to 18 months. In parallel, we have developed a major proposal for an Alberta/Canada Fusion Energy Institute, which has been forwarded to officials in the province of Alberta and the federal government. We are requesting funding in the present proposal to continue a research program which we have already established in collaboration with the Lawrence Livermore National Laboratory to study the improved advanced ignition schemes. This program will investigate the generation, transport and deposition of fast electron and proton energy which is required for the fast ignition process and the backscatter and electron generation for shock ignition. In so doing we will devleop Candian expertise in niche areas of target fabrication and x-ray diagnostics and make a significant step towards making laser fusion energy a reality.

在最近的一项研究中，加拿大工程师学院已经提出了几项建议，涉及对加拿大未来的清洁能源途径的追求。这些建议之一是加拿大重新建立了一项研究计划，以追求融合能源，这是人类的最终丰富而清洁的能源。当前的建议是建立加拿大研究工作的关键一步，以惯性融合能量（IFE）着重于追求有希望的新的高级点火概念。这些概念是快速的点火和冲击点火开关，其中超时（20 picsecond）激光脉冲可以触发融合反应的点火或强烈的均匀脉冲（200-500PS）引起冲击波，从而在压缩燃料弹丸中产生点火温度尖峰。两种技术都可以将整个激光系统的大小降低至少两个因子，这在加速融合反应器系统的开发周期中具有显着影响。目前，世界正在等待来自劳伦斯·利弗莫尔国家实验室（LLNL）国家点火设施的2个巨型激光系统的突破，这应该证明使用传统的自我点火计划在未来6到18个月内使用传统的自我点火计划的可行性。同时，我们已经为艾伯塔省/加拿大融合能源研究所提出了一项主要建议，该研究所已转发给艾伯塔省和联邦政府的官员。我们要求在本提案中提供资金，以继续与劳伦斯·利弗莫尔国家实验室合作建立的研究计划，以研究改进的高级点火计划。该程序将研究快速点火过程以及反向散射过程和电子生成所需的快速电子和质子能量的产生，传输和沉积。通过这样做，我们将在目标制造和X射线诊断的利基领域Devleop Candian专业知识，并迈出了使激光融合能量成为现实的重要一步。
