abstract = {Deep understanding of the structural composition and growth
of biological specimens is becoming increasingly important
for the development of bio-based and sustainable material
systems. Full-field nano-computed tomography is particularly
suitable for this purpose as it allows for non-destructive
3D imaging at high spatial resolution. However, most
biological samples are functionalized by water and respond
sensitively to any changes in climate conditions,
specifically relative humidity, by adjusting their material
moisture content. To date, only a limited number of
tomography instruments offer an in situ climate control
option to users. These, however, are limited either by the
range of relative humidity states, the long times required
to change the climate state, or obstruction or attenuation
of the beam. Here, the first fully automatized climate cell
for in situ full-field nanotomography is presented. It has
been designed, built and integrated at the nanotomography
station at the P05 imaging beamline, operated by Hereon at
the DESY storage ring PETRA III, Germany. The highly
flexible and windowless design allows the humidity dependent
swelling and shrinking of lignified plant cell walls to be
studied in situ, using phase contrast nanotomography. The
concept of this climate chamber can easily be integrated
into other setups. It operates in the relative humidity
range of $0–90\%$ and can be controlled in a temperature
range of 10–50°C. Climate conditions can be adjusted at
any time, remotely from the control hutch by using a
humidity generator. Results show that the developed setup
maintains a stable climate during the entire duration of a
tomographic scan at different humidities and does not
obstruct the sample or hinder the imaging conditions. During
the tomographic investigation the sample remains stable in
the flow of the air stream and shows typical cell wall
swelling and shrinking behaviour depending on the
equilibrium moisture content. This new climate cell is now
available to all users of the P05 nanotomography instrument
for conditioning samples, serving a wide range of scientific
applications.},
