abstract = {The research reactor Heinz Maier-Leibnitz (FRM II) is a
modern high flux neutron source which feeds some 30 state of
the art neutron beam instruments. Currently 24 are
operational, others in commissioning or under construction.
The newly built neutron single crystal diffractometer
BIODIFF is especially designed to collect data from crystals
with large unit cells. The main field of application is the
structural analysis of proteins, especially the
determination of hydrogen atom positions. BIODIFF is a joint
project of the Jülich Centre for Neutron Science (JCNS) and
the FRM II. Typical scientific questions addressed are the
determination of protonation states of amino acid side
chains (see e. g. [1,2]) and the characterization of the
hydrogen bonding network between the protein active centre
and an inhibitor or substrate. BIODIFF is designed as a
monochromatic instrument. By using a highly orientated
pyrolytic graphite monochromator (PG002) the diffractometer
is able to operate in the wavelength range of 2.4 Å to
about 5.6 Å. Contaminations of higher order wavelengths are
removed by a neutron velocity selector. To cover a large
solid angle the main detector of BIODIFF consists of a
neutron imaging plate in a cylindrical geometry with online
read-out capability. A fast Li/ZnS scintillator CCD camera
is available for additional detection abilities. An optical
CCD-camera pointing at the sample position is used to
quickly align the crystal with respect to the neutron beam.
The main advantage of BIODIFF is the possibility to adapt
the wavelength to the size of the unit cell of the sample
crystal while operating with a clean monochromatic beam that
keeps the background level low. BIODIFF is equipped with a
standard Oxford Cryosystem “Cryostream 700+” which
allows measurements in the temperature regime from 90K up to
500K (see Figure underneath).},
