Paper Abstract

We present the latest design of an off-plane reflection grating array for the Constellation-X X-ray Grating Spectrometer. The off-plane design can easily demonstrate the baseline requirements of resolution, R > 1250 and throughput, effective area > 1000 cm2 from 0.3 - 1.0 keV. Furthermore, the flexibility of the design allows for several avenues for optimization of these factors. We consider two configurations, 3 m and 9 m from the focal plane using a 20 m focal length telescope. The trade-offs between the two options are discussed.
