cushions, which enables them to be easily moved. The name “Tanzboden” (dance floor) used for this technique comes from the components of the instruments sliding on
air cushions, as waltzers
on a dance floor. At the
time this was quite new,
and was perfected by
Guy Gobert who made a
demonstration by placing
Maier-Leibnitz on such an
air cushion platform and
gliding it about (Fig. 5.1).
It was used for other triple
axis spectrometers but
after greatly reducing the
distances between tables,
which were far too long in the first instrument leading to a large and unacceptable loss of measured intensity.
5.1.3 Elastic Scattering
The instruments proposed and built for these studies can be classified in three categories.
