Cluster is a European Space Agency mission of four spacecraft launched into orbit around the Earth. The four spacecraft carry 11 instruments each, together designed to probe the physical processes that control the collisionless plasma environment of the Earth. The spacecraft fly in a tetrahedron formation, allowing the three dimensional structure of the plasma to be measured in-situ for the first time, and distinguished from variations in the plasma as a function of time. The Cluster orbit takes the spacecraft through regions of the Earth's magnetosphere that are the sites of fundamental processes in collisionless plasmas, including magneto-hydrodynamic (MHD) turbulence in the solar wind, energy partition in collisionless shock processes, energy transfer through reconnection and other processes at the magnetopause, energy flow into the magnetosphere through the cusps, particle acceleration in the auroral zone, and substorm processes, including reconnection and current disruption, in the magnetotail. Imperial College is the Principal Investigator institution for the flux-gate magnetometer (FGM) that forms part of each Cluster payload. The magnetic field is a key parameter in understanding the behaviour of collisionless plasmas, and therefore the FGM instrument contributes to nearly every scientific study carried out using Cluster data. As the PI institution we are responsible for the ongoing routine operation and continued health of the four FGM instruments, the maintenance of the link through which data is supplied in real time to other instruments on the payload, and the calibration and delivery of high resolution data suitable for detailed scientific analysis to the Cluster Active Archive (CAA), set up and run by ESA. The purpose of this grant is to request support for the continuation of these responsibilities for the remainder of the Cluster mission, currently planned to run until at least Dec 2009, with the possibility of an extension for a further 3 years.

星团是欧洲航天局发射进入地球轨道的四个航天器的使命。这四个航天器各携带11个仪器，共同设计用于探测控制地球无碰撞等离子体环境的物理过程。该航天器以四面体的形式飞行，允许首次在现场测量等离子体的三维结构，并将其与等离子体随时间的变化区分开来。星团轨道将航天器带过地球磁层的一些区域，这些区域是无碰撞等离子体基本过程的发生地，包括太阳风中的磁流体动力学湍流、无碰撞冲击过程中的能量分配、磁层顶通过重连和其他过程进行的能量转移、通过尖点进入磁层的能量流、极光区的粒子加速、以及磁尾的亚暴过程，包括重连和电流中断。帝国理工学院是磁通门磁力计的主要研究机构，磁通门磁力计是每个集群有效载荷的一部分。磁场是理解无碰撞等离子体行为的关键参数，因此FGM仪器几乎有助于使用Cluster数据进行的所有科学研究。作为PI机构，我们负责四台切割女性生殖器仪器的日常运行和持续健康，维护将数据真实的实时提供给有效载荷上其他仪器的链路，以及校准和向欧空局建立和运行的集群活动档案馆（CAA）提供适合详细科学分析的高分辨率数据。这笔赠款的目的是请求支助继续履行该组使命的其余部分的这些职责，目前计划至少持续到2009年12月，并有可能再延长3年。
