Abstract

The Lynx X-ray Grating Spectrograph (XGS) is required to provide high throughput, 4000 cm^2, high resolving power, R>5000, soft X-ray spectroscopy from 0.2-2.0 keV. In this regime of astrophysically important lines, the XGS will probe key science topics such as the distribution of diffuse hot baryons, the feedback environments near supermassive black holes, and the physics of stellar atmospheres and accretion. We present here the conceptual design of an XGS consisting of an array of reflection gratings placed in the off-plane mount. The configuration of the array and the associated detector readout are discussed. Finally, the expected X-ray performance is characterized.
