X-Ray Concentrator Will Expand Window On High-Energy Universe
...the protein works. However, the process takes many hours and dozens of crystallograms, partlybecause the X-rays are relatively weak. Now the x-ray optics produce muchbrighter beams on the tiny organic samples, greatly decreasing the time neededto collect enough data to obtain a complete structure.
