The ID31 Sample Station consists of multiple stacked stages
|
||
|
|
(figs~\ref{fig:assemblage} and~\ref{fig:exp_setup}):
|
||
|
|
|
||
|
|
\begin{itemize}
|
||
|
|
\item \emph{translation stage}: travel range of \(T_y =
|
||
|
|
\SI{\pm5}{\milli\metre}\). Permits to scan the sample through the X-ray.
|
||
|
|
\item \emph{tilt stage}: rotates the sample around the \(y\) axis by
|
||
|
|
\(\theta_y = \ang{\pm3}\). The rotation axis is aligned with the focusing
|
||
|
|
point of the X-ray in order to allow experiments such as X-ray reflectivity.
|
||
|
|
\item \emph{air bearing spindle}: rotate the sample around the vertical axis
|
||
|
|
with an angular speed that varies from \(\dot{\theta_z} = \SI{1}{rpm}\) for
|
||
|
|
light samples (\(M<\SI{1}{\kilo\gram}\)) to \(\dot{\theta_z} = \SI{60}{rpm}\)
|
||
|
|
for heavy samples (\(M=\SI{50}{\kilo\gram}\)).
|
||
|
|
\item \emph{long-stroke Stewart platform}: allows a fine positioning of the
|
||
|
|
sample in all 6 degrees of freedom (DoF).
|
||
|
|
\item \emph{gravity compensation system}: consists of two motorized mass that
|
||
|
|
can be positioned around a circular guidance in order to perfectly aligned the
|
||
|
|
center of mass with the spindle rotation axis.
|
||
|
|
\item \emph{sample environment}: permits to study samples under wide range of
|
||
|
|
condition: low (\(\SI{1.2}{\kelvin}\)) to high (\(\SI{2000}{\kelvin}\)) temperatures, high
|
||
|
|
magnetic field (\(\SI{8}{\tesla}\)), etc.
