摘要

A new imaging-plate X-ray diffractometer of theWeissenberg-camera type with an adjustable multilayer-linescreem system (IPD-WAS) has been developed. Prior to datacollection, IPD-WAS automatically aligns an axis of a samplecrystal and sets the multilayer-line (MLL) screens. ForWeissenberg photography, IPD-WAS system uses two cylindricalimaging plates (IPs). The IPs are read by a rotary readoutmechanism. Owing to the good performance of the adjustableMLL screen system and the rotary readout mechanism, IPD-WASachieves a data acquisition time of about one hour with reflectiondata of sufficient quality, which is suitable for time-resolved X-raycrystallography. IPD-WAS also enables faster crystal structuredeterminations of small molecules, including unstable crystals.
