Critical Angle Transmission Grating spectrometer development for the International X-Ray Observatory
The International X-ray Observatory (IXO, formerly Constellation-X) is a next-generation astronomical X-ray Observatory, a joint project between NASA, the European Space Agency (ESA), and the Japanese Aerospace Exploration Agency (JAXA). It is foremost a spectroscopic mission, and will be up to 100 times more powerful than currently operating X-ray observatories.At MIT, the Space Nanotechnology Lab is developing Critical Angle Transmission gratings (CAT). We are currently studying design concepts using the CAT in a transmission grating spectrometer for IXO.
Here we will provide basic information and resources for spectrometer study.
These responses are for exploration of the scientific gains from high resolution using a prototype Critical Angle Transmmission grating spectrometer.
NOTE: None of the area or efficiency files have yet been endorsed by the Project. The models used here are our best current evaluation of component performance criteria.
