Plasma is an ionized gas with free electrons, ions, and neutral particles. Fusion has been considered an ultimate energy solution which is inexhaustible and also friendly to environment. Tokamak is a device to confine plasma using magnetic field. Pursues to build commercial fusion reactor are hindered by anomalous transport of heat and particles in the reactor. Instabilities and turbulences are the main candidates for causing anomalous transport, but the exact mechanism is still largely unknown. In addition, many technical and engineering problems have to be solved before commercial fusion reactors can be built. The proposed research on the Saskatchewan Torus-Modified (STOR-M) tokamak addresses several key physics and technical issues for future fusion reactor: effective fueling using compact torus injection to reduce tritium fuel recycling requirement; resonant magnetic perturbation to suppress instabilities which may degrade plasma confinement and even cause termination of reactor operations. Since termination of the Canadian national fusion program and the closure of the TdeV tokamak in 1997, the STOR-M tokamak has been the only magnetic fusion research facility in Canada. The ITER (International Thermonuclear Experimental Reactor) is the largest scientific project participated in by seven parties (EU, USA, Japan, Russia, China, Korea, and India. Unfortunately, Canada is now the only G8 country outside the ITER program. It is important for Canada to maintain a small, yet active fusion research program on STOR-M which is vibrant and visible to the international fusion community. In addition, research on plasma technologies will be carried out for industrial and medical applications using existing plasma reactors in the Laboratory and a new dense plasma focus device to be built. Research on the plasma aided material processing is also related to some extent to fusion plasmas. At the edge of a tokamak, plasma density and temperature are relatively low. Techniques used for diagnosing edge plasma parameters in tokamaks can also be used for processing plasmas.

血浆是一种带有游离电子，离子和中性颗粒的电离气体。融合被认为是一种最终的能源解决方案，它是无尽的，对环境也友好的。 Tokamak是使用磁场限制血浆的设备。反应器中热和颗粒的异常运输阻碍了追求商业融合反应器的追求。不稳定性和湍流是导致异常运输的主要候选者，但确切的机制仍然很少知道。此外，在建立商业融合反应堆之前，必须解决许多技术和工程问题。 拟议的关于萨斯喀彻温省修饰（Stor-M）Tokamak的研究涉及未来融合反应堆的几个关键物理和技术问题：使用紧凑型圆环注射以减少tri燃料燃料回收要求的有效加油；共振磁扰动以抑制可能降解血浆限制甚至导致反应堆操作终止的不稳定性。 自1997年终止加拿大国家融合计划和TDEV Tokamak的关闭以来，Stor-M Tokamak一直是加拿大唯一的磁融合研究设施。 ITER（国际热核实验反应堆）是七个政党（欧盟，美国，日本，俄罗斯，中国，韩国和印度参加的最大科学项目。 此外，将使用实验室中现有的等离子体反应器以及将要构建的新型血浆焦点设备进行有关工业和医疗应用的血浆技术研究。 血浆辅助材料处理的研究在一定程度上与融合等离子体有关。 在Tokamak的边缘，血浆密度和温度相对较低。用于诊断Tokamaks中边缘等离子体参数的技术也可以用于处理等离子体。
