N1 - Funding Information:
I would like to recognize the significant contributions that group members have made to reflection gratings and their implementation over the last several years. These members include Casey DeRoo, Ben Donovan, Fabien Grisé, Jake McCoy, Ross McCurdy, Drew Miles, Tom Peterson, Ted Schultz, James Tutt, and Ningxiao Zhang. Their contributions form the basis for this paper. I would also like to thank the terrific staff members at the Penn State Nanofabrication Lab, especially Chad Eichfeld, Michael LaBella, Guy Lavallee, Bill Drawl, and Bangzhi Liu. In addition, thanks are due to the x-ray testing support staff at the PANTER X-ray Test Facility, including Vadim Burwitz, Gisela Hartner, Carlo Pelliciari, and Marlis La Caria, as well as Eric Gullickson at the Advanced Light Source Beamline 6.3.2. Finally, I would like to thank the Lynx mission team, especially Jessica Gaskin and the ACO engineers. This work was supported by the National Aeronautics and Space Administration under Grant Nos. NNX12AI16G, NNX12AF23G, and NNX15AC42G, and internal funding from the Pennsylvania State University. The author has no relevant financial interests in the paper and no other potential conflicts of interest to disclose.

N2 - The Lynx X-ray Grating Spectrograph (XGS) is responsible for providing high throughput and spectral resolution for soft x-ray energies. This instrument will help characterize the formation of galaxies and a large-scale structure in the universe. Such goals require large effective areas, >4000 cm2, and high resolving power, R > 5000, over much of the low-energy band, 0.2 to 2.0 keV. A concept design for the XGS using reflection gratings has the potential to achieve these requirements. The design uses achievable grating parameters, efficient packing of the grating array, and a compact detector layout. The concept is presented along with a detailed discussion of the considerations made in its determination.
