Protein Diffractometer

< KSU-5>

 This is a specialized instrument for structural analysis of biopolymers such as proteins. Since the rotation stage for the sample is used to measure a crystal of approximately 10 μm, the rotation center displacement of the rotary stage for the sample is kept at 1 μm or less. Also since fluctuation of the sample caused by high-intensity X-rays is a problem, this instrument is equipped with a shutter that can be controlled to turn on and off in milliseconds. The X-ray CCD camera can approach the sample to a proximity of 40 mm to cover sufficiently the diffracted rays required for analysis. This instrument is now in service at the KEK PF (Photon Factory) BL05 in Japan. -

Attenuator

<KEI-AT20R>

This is one of our standard attenuator unit which is useful for incident optics in many synchrotrons. This unit is possible to attenuate a direct incident beam for getting a proper beam by changing many attenuators automatically by the rotating of a motor shaft. You can also put it in a chamber like a right photo.
