The Off-plane Grating Rocket Experiment (OGRE) is a NASA funded project to enable the development and testing of technologies suited for the next generation of astronomical X-ray observatories [1]. The mission is a collaborative experiment led by Penn State University (USA) who are manufacturing the X-ray gratings and combining them with collecting optics from Goddard Space Flight Centre (USA) and an X-ray camera built by XCAM Ltd in Northampton (UK). OGRE will use a novel array of X-ray silicon optics to direct X-rays onto off-plane soft X-ray gratings which disperse the spectrum across a focal plane of Electron-Multiplying ChargeCoupled Devices (EMCCDs). After launching on a parabolic trajectory, OGRE will observe the X-ray spectrum of Capella during a ~5 minute window and aims to collect the highest resolution astronomical soft X-ray spectrum to date. The Open University has been contributing to the OGRE collaboration by characterising the prototype camera [2], supporting the design of the flight model camera, and developing algorithms for in-flight data-processing and reduction. This prior work will feed into the studentship, providing a basis from which to continue. With supervision and training, the student will take the lead in one or more of the following areas, which will be determined as the project proceeds, according to the wider developments of the mission and the preferences and abilities of the individual student: Characterising the performance of the Flight Model camera; Developing ground instrumentation and software to monitor and operate the camera during its flight; Understanding the OGRE camera system's behaviour and performance; Team meetings between the Open University, XCAM Ltd and Penn State University; Supporting the integration of the OGRE camera, launch of the rocket and the experiment during flight; Analysing the flight data including performance of the instrumentation during the mission; Further testing and development of the EMCCD detectors used in the camera to explore their capabilities for future X-ray mission such as the Lynx X-ray Observatory.

离机光栅火箭实验 (OGRE) 是 NASA 资助的一个项目，旨在开发和测试适合下一代天文 X 射线观测站的技术 [1]。该任务是由宾夕法尼亚州立大学（美国）领导的一项合作实验，该大学正在制造 X 射线光栅，并将其与来自戈达德太空飞行中心（美国）的收集光学器件和 XCAM Ltd 位于北安普顿（英国）制造的 X 射线相机相结合。 OGRE 将使用新型 X 射线硅光学器件阵列将 X 射线引导到离面软 X 射线光栅上，该光栅将光谱分散到电子倍增电荷耦合器件 (EMCCD) 的焦平面上。在抛物线轨道上发射后，OGRE 将在约 5 分钟的窗口内观察五车二的 X 射线光谱，旨在收集迄今为止最高分辨率的天文软 X 射线光谱。开放大学一直通过表征原型相机 [2]、支持飞行模型相机的设计以及开发飞行中数据处理和缩减算法来为 OGRE 合作做出贡献。之前的工作将融入学生身份，为继续学习提供基础。通过监督和培训，学生将在以下一个或多个领域发挥主导作用，这些领域将根据任务的更广泛发展以及个人学生的偏好和能力，随着项目的进展而确定： 表征飞行模型相机的性能；开发地面仪器和软件以在飞行过程中监控和操作相机；了解 OGRE 摄像头系统的行为和性能；开放大学、XCAM Ltd 和宾夕法尼亚州立大学之间的团队会议；支持OGRE相机、火箭发射和飞行中实验的集成；分析飞行数据，包括任务期间仪表的性能；进一步测试和开发相机中使用的 EMCCD 探测器，以探索其未来 X 射线任务（例如 Lynx X 射线天文台）的能力。
