a Schematics of a six optic X-ray cavity optics layout that provides a small range of tunability. b Arrows indicating coordinated motion required for M1 and M2 to extend the cavity length by going from the blue to the red beam path, with a fixed input and output beam path. c Arrows indicating coordinate motion required for M1, M2, and M3, to adjust the cavity resonance wavelength, and hence the photon energy of the reflected X-rays, while maintaining the overall cavity length as well as output beam path
