摘要：

In order to speed up data collection in macromolecular structure analysis, it is desirable to use large position sensitive detectors and/or wide wavelength band of radiation impinging on the crystal. At present, on a conventional monochromatic diffractometer equipped with a gas-filled area detector, a typical recording time for a protein crystal with a volume of several cubic millimetres is about three weeks. We are developing an instrument equipped with several position sensitive photomultiplier detectors and a beam geometry which allows the selection of a broad wavelength band. In this way we expect to be able to examine in the same time crystals with larger unit cells and smaller volumes, thereby increasing the range of accessible problems.
