The Diffractometer - Experimental Hutch

A heavy load 2+4-circle diffractometer + 2 circle analyzer stage is set up in the big evacuable vessel to perform scattering experiments (bulk or surface) either in the vertical or horizontal scattering planes. Working in the reciprocal space (hkl mode) is also possible.

A picture of the diffractometer:

          4-circle part

theta sample vertical-plane scattering angle

          delta detector vertical-plane scattering angle

phi sample rotation

chi sample tilt in the plane xz

+ 2-circle

mu sample circles rotation in the horizontal plane (yz).

gamma Detector arm rotation in the horizontal plane (yz).

tau sample translation stage along phi axis
