Abstract
This thesis discusses the developments of the EM-CCD camera system for the Off-plane Grating Rocket Experiment, or OGRE mission. The key science accomplishments look at the characterisation of devices of the same architecture as those to be used on the mission flight, a model of the complete project payload to determine its mission effectiveness, and an event processing system designed to find events within the images acquired as well as methods to identify events of interest. Chapters 1-4 focus on the backgrounds of x-ray spectroscopy and the OGRE project detailing knowledge required for understanding the work carried out. As the model created is based on the theories and fundamental science behind the OGRE system, this section, chapter 5, is before the experimental set-up discussed in chapter 6. The model based on ideal scenarios highlighted a need to restructure the mission payload as the initial design failed to reach the minimum mission requirements unless changes were implemented. These suggestions were passed on and design changes implemented based on these findings. Chapter 7 details the characterisation of the CCD207-10, and EM-CCD similar to the flight detectors for the project, showing the standard format for incident X-rays, as well as finding offsets present in the device and looking at other significant factors which any affect observations such as dark current, giving confidence the flight devices will operate satisfactorily. The event processing is discussed in chapter 8 with comparisons of observations for X-rays from two different sources with methods of identifying the source based on the observed signal looked at.
