More Information
Summary:Charged Coupled Devices （CCDs） have been successfully used in several low energy X-ray astronomical satellites over the past two decades. Their high energy resolution and high spatial resolution make them a perfect tool for low energy astronomy, such as observing the formation of galaxy clusters and the environment around black holes. The Low Energy X-ray Telescope （LE） group is developing a Swept Charge Device （SCD） for the Hard X- ray Modulation Telescope （HXMT） satellite. A SCD is a special low energy X-ray CCD, which can be read out a thousand times faster than traditional CCDs, simultaneously keeping excellent energy resolution. A test method for measuring the charge transfer efficiency （CTE） of a prototype SCD has been set up. Studies of the charge transfer inefficiency （CTI） with a proton-irradiated SCD have been performed at a range of operating temperatures. The SCD is irradiated by 3× 10Sere-2 10 MeV protons.
