Model GHM-3SP
This high precision slit has a drive mechanism with improved accuracy in comparison to the GHM-3S model. Four linear encoders can be installed in order to monitor independent motion of each blade. Special care is taken during the assembly and adjustment in order to assure the best performance. This unit was used in an X-ray photon correlation experiment with synchrotron radiation from
TRISTAN Main Ring at KEK, Tsukuba ( S.Kikuta et al., Jpn. J. of Synchrotron Radiation v.10, 1997, p.126 - in Japanese, abstract in English ).
