项目摘要

Imperial College London leads a consortium which has proposed a magnetometer for the Solar Orbiter mission. The magnetometer is a key instrument to the science goals of the mission and comprises two sensors located on a boom in shadow behind the spacecraft, an electronics box in the spacecraft and associated harnesses. The proposed design measures the magnetic field in the vicinity of the spacecraft with sufficient precision to characterise phenomena from large scale structures to ion kinetic scales, is a mature design and complies with the mass and power requirements of the Payload Definition Document. This proposal is for a limited amount of work to support the Imperial College London team until April 2010. During this time, we will undertake instrument leadership activities, coordinating our activities with the European Space Agency, NASA and other instrument teams. We will also address the most important technical issue of the instrument, which is temperature control. The sensor will sit at the end of a boom, in continual shadow, and hence will get cold. We will undertake detailed modelling work, to determine precisely how cold it is expected to run, and how we can keep the temeprature within allowable limits using heaters: specifying the required heater power is a key goal. We will aos investigate whether we can run our sensors at temperatures lower than that to which they have previously been qualified.

伦敦帝国学院领导一个财团，该财团提出了用于太阳能轨道特派团的磁力计。磁力计是该任务科学目标的关键工具，包括两个传感器，位于飞船后面的阴影中的繁荣时期，这是航天器中的电子盒和相关的安全带。所提出的设计以足够的精确度来测量航天器附近的磁场，以表征从大型结构到离子动力学尺度的现象，是一个成熟的设计，符合有效载荷定义文档的质量和功率要求。该建议是为了支持伦敦帝国学院团队的大量工作，直到2010年4月。在此期间，我们将进行仪器领导活动，并与欧洲航天局，NASA和其他仪器团队协调我们的活动。我们还将解决该仪器最重要的技术问题，即温度控制。传感器将坐在繁荣的尽头，持续的阴影，因此会变冷。我们将进行详细的建模工作，确切确定预期运行的冷，以及如何使用加热器保持允许限制的限制：指定所需的加热器功率是关键目标。我们将调查是否可以在低于以前有资格的温度下运行传感器。
