The baseline configuration for the International X-ray Observatory (IXO) includes a soft x-ray grating spectrometer as part of its instrument complement to provide a spectral resolution of R >3000 over the 0.3 - 1 keV band with >1000 cm2 effective collecting area. An Off-Plane X-ray Grating Spectrometer (OP-XGS) is being proposed to the project to meet this need, using experience gained with the current generation of reflection gratings already flown on rocket experiments. These rocket experiments have demonstrated R of >100 with wire grid collimators and objective gratings that produce large point spread functions. Prototype gratings fabricated for the IXO project have achieved adequate throughput to obtain the IXO effective area requirement while resolution tests have demonstrated λ/Δλ > 200 when used with a 3 arc minute (angular resolution) telescope. When combined with the IXO telescope performance, the resulting spectral resolution is well over the IXO requirement. The conceptual design, two trade options, and predicted performance of this system is presented here, along with the technology developments that will be needed to achieve the desired performance.
