Support for accelerator physics research including ARIEL

有了先进的稀有同位素实验室(ARIEL)，TRIUMF正在进入一个以稀有同位素为基础的研究的新时代，允许同时将三个稀有同位素束输送到前沿实验中。2010年6月，加拿大创新基金会(CFI)批准了对TRIUMF超导电子直线加速器(e-linac)的资本资助，作为Ariel的第一阶段。该加速器于2014年9月成功地发射了第一个低功率束流。随着第二阶段(Ariel-II)的批准，CFI和五个省为该项目提供的资金总额接近1亿美元。它包括两个新的靶站的基础设施，以及电子诱导的光裂变和质子诱导的裂变、层裂和碎裂反应产生的同位素的离子束输送系统。放射性同位素将被运送到核、核天体物理和材料科学研究以及医学应用的实验中。有了电子直线加速器，TRIUMF拥有两个用于生产同位素的高功率驱动束流加速器，这两个加速器都带来了操作挑战，需要开发先进的系统和许多加速器科学领域的专业知识。此外，稀有同位素的束流准备(电荷育种和束流净化)和后期加速需要系统的性能改进。通过Ariel，TRIUMF能够加强和扩展其在加速器物理方面的专业知识，重点放在三个核心专业领域：1.超导射频(SRF)，2.次级靶和离子源，以及3.束流物理。这份申请是为了继续为在TRIUMF从事加速器物理的UVic研究生提供NSERC支持，并支持该领域一名新的UVic教员的研究。

With the Advanced Rare Isotope Laboratory (ARIEL), TRIUMF is moving into a new era of rare isotope-based research allowing three simultaneous rare isotope beams to be delivered to leading edge experiments. 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 ARIEL. The accelerator delivered successfully first low power beam in September 2014. With the second phase (ARIEL-II) approved, total funding for the project from CFI and five provinces is almost $100M. It 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. Radioisotopes will be delivered to experiments for nuclear, nuclear astrophysics, and material science research, as well as for medical applications. With the e-linac, TRIUMF has two high power driver beam accelerators for the production of isotopes, both which present operational challenges and require the development of advanced systems and expert knowledge in many areas of accelerator sciences. In addition, the beam preparation (charge breeding and beam purification) and post acceleration of rare isotopes require systematic performance improvements. Through ARIEL, TRIUMF has been able to strengthen and extend its expertise in accelerator physics with a focus on three core areas of expertise, 1.Superconducting radiofrequency (SRF), 2.Secondary targets and ion sources, and 3.Beam Physics. This application is a request to continue NSERC support for UVic graduate students engaged in accelerator physics at TRIUMF and to support the research of a new UVic faculty member in this field.
