HV Diffractometer


This diffractometer was manufactured for research of solid surfaces and thin
film surfaces and interfaces. To observe the X-rays diffracted from the
surface of a sample in any direction, this instrument has a four-axis
structure comprising 2+2 axes. With an ultra-high vacuum tank that allows
on-the-spot observation, the axes are assembled so that the displacement of
the rotating centers is less than 50μm. The UHV diffractometer has two degrees of freedom (DOF) on the sample and two independent DOF on the detector. The diffractometer is about 3.2 m x 3.2 m x 2.3 m in dimension. This instrument is now in service in the SPring-8 (Super Photon ring-8 GeV) BL13XU in Japan.

Ultra High Load Rotation Stage

<MAX-G 400 & 600>

MAX-G is one of highest-precision goniometer which can be heavy-loaded and do not change the precision from no loaded case.



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.
