Capital funding for a superconducting electron linear accelerator at TRIUMF, known as the e-linac, was approved through the Canada Foundation for Innovation (CFI) in June 2010, as the first phase of the advanced rare isotope laboratory (ARIEL). The accelerator was successfully commissioned in September 2014. CFI has approved funding for the second phase (ARIEL-II) and provincial approval for matching funding is nearly finalized. ARIEL II includes infrastructure for two new target stations and ion beam delivery systems for isotopes produced by electron-induced photo-fission as well as by proton-induced fission, spallation and fragmentation reactions. These radioisotopes are then delivered to experiments for nuclear, nuclear astrophysics, and material science research, as well as for medical applications.******This application is a request to renew NSERC support for our graduate students to allow them to continue to participate in ARIEL, thereby receiving valuable training in accelerator physics. While capital costs are covered through the approved CFI funding, CFI does not support the training of graduate students.******Our students have made valuable contributions to ARIEL in many areas. Students participated in the design, construction, and operation of view screen beam profile monitors, that have been used extensively in the commissioning of the e-linac. A student has developed a novel design for a beam deflector, necessary for future upgrades of the e-linac, using superconducting RF, and a prototype will be tested soon. Other students are working on simulation and tests to finalize the design of challenging elements of the target station. This includes the photo-converter, that produces the high energy photons needed for photo-fission immediately in front of the target, and the ion extraction optics system, that accelerates and focuses the rare isotope ions released from the target.******Within a few years, the e-linac will begin producing isotopes for science, significantly expanding the isotope research program at TRIUMF. This period will offer an excellent opportunity for students to learn important skills in accelerator physics.

2010年6月，加拿大创新基金会（CFI）批准了TRIUMF超导电子直线加速器的资本资金，作为高级稀有同位素实验室（ARIEL）的第一阶段。该加速器于2014年9月成功投入使用。原住民基金会已经批准了第二阶段（ARIEL-II）的资金，省级批准配套资金的工作即将完成。ARIEL II包括两个新目标站的基础设施和用于电子诱导光裂变以及质子诱导裂变、溅射和碎裂反应产生的同位素的离子束输送系统。这些放射性同位素然后被运送到核实验，核天体物理学和材料科学研究，以及医学应用。这个应用程序是一个请求更新NSERC支持我们的研究生，让他们继续参与ARIEL，从而获得加速器物理学的宝贵培训。虽然资本成本是通过批准的CFI资金支付，但CFI不支持研究生的培训。我们的学生在许多领域为ARIEL做出了宝贵的贡献。学生们参与了视屏束流剖面监视器的设计、建造和操作，这些监视器已广泛用于电子直线加速器的调试。一名学生开发了一种新颖的光束偏转器设计，这是未来电子直线加速器升级所必需的，使用超导RF，很快将对原型进行测试。其他学生正在进行模拟和测试，以最后确定目标站具有挑战性的组成部分的设计。这包括光转换器，它产生光裂变所需的高能光子，直接在目标前面，和离子提取光学系统，加速和聚焦从目标释放的稀有同位素离子。在几年内，电子直线加速器将开始为科学生产同位素，大大扩展了TRIUMF的同位素研究计划。这段时间将为学生提供一个极好的机会，学习加速器物理学的重要技能。
