The first experimental hutch contains a heavy duty Huber diffractometer with vertical rotation axis and FReLoN 2K CCD camera.

Beam definition

The beam in EH1 can be focused using the IVT in OH1 down to a size of ~ 45 x 6 micron (horizontal x vertical) for an energy range of 18-75 keV (see figure here). The beam then can be further defined using the slit system situated on the 'huber tower'. This consists of a set of xx type slits (slit6) mounted infront of a further set of huber tube slits (see image below). The tube slits are in-vacuum allowing a means of defining the x-ray beam as close to the sample position as possible and reduce the effect of air scattering. They also act as anti-scatter slits when s6 is used to define the beam. For users doing standard diffraction experiments in EH1 using the FReLoN camera, it is recommend to use a 50 x 50 micron beamsize to match the pixel size of the detector.
