Our Sun is vital for our existence; it is a source of immense power that allows life to exist and thrive. The Sun's eruptive activity, which is driven by magnetic fields, causes hazardous space weather conditions at Earth. Solar eruptions can accelerate energetic particles consisting of electrons, protons and ions that can cause significant damage to satellite electronics and pose a severe radiation risk for crewed spaceflight. Space weather directly impacts our everyday lives due to our ever-growing levels of space exploration, space tourism and dependence on modern technology. The UK Met Office now provides space weather forecasts with space weather appearing on the UK's National Risk Register.Investigating the origin and acceleration of solar energetic particles remains at the forefront of solar heliospheric research and it is the focus of the recently launched Solar Orbiter and Parker Solar Probe missions. It is an exciting time to work on this project due to the launch of new space missions, the existence of decade-long Solar Dynamics Observatory datasets covering the entire previous solar cycle, the development of new plasma composition techniques, and the increased activity during the new solar cycle. During this fellowship, I will combine magnetic field observations, magnetic models and plasma measurements in space with a novel composition analysis technique to understand the origin of solar energetic particles. I will use magnetic field parameters and eruption characteristics along with enhancements in plasma composition to identify source regions of solar energetic particles in advance as required by space weather forecasters.

我们的太阳对我们的存在至关重要。它是巨大的力量来源，可以使生活存在和繁荣。由磁场驱动的太阳的爆发活动会导致地球上的危险空间天气条件。太阳喷发可以加速由电子，质子和离子组成的能量颗粒，这些颗粒可能会对卫星电子造成重大破坏，并对机组人员太空飞行构成严重的辐射风险。由于我们不断增长的太空探索，太空旅游和对现代技术的依赖水平，太空天气直接影响了我们的日常生活。英国大都会办公室现在提供了太空天气预报，并在英国的国家风险登记册上出现了太空天气。对太阳能颗粒的起源和加速度进行了评估，这仍然是太阳能地球层研究的最前沿，它是最近发射的太阳轨道和派克太阳能探针的重点。由于启动了新的太空任务，十年的太阳能动力学天文台数据集，涵盖了整个前太阳能周期，新的等离子体组成技术的发展以及在新的太阳能周期期间的活动增加，因此这是一个令人兴奋的时间。在此研究金期间，我将在空间中将磁场观测，磁模型和等离子体测量与一种新颖的组成分析技术相结合，以了解太阳能颗粒的起源。我将使用磁场参数和喷发特性以及血浆组成中的增强，以根据太空天气预测者要求提前识别太阳能颗粒的来源区域。
