Neutron Spin Echo (NSE) is a relatively "new" neutron
spectroscopy technique, if we consider the 1980-s as recent
years... It is however undeniable, that for a long time there
was only one instrument available for users, thus few of them
had a chance to gain some experience with it. In addition, it
is measuring this obscure S(q,t) rather than the very friendly
S(q,omega) as all the other neutron spectroscopy instruments.
During experiment nothing appears to move, but only 20+
currents are changing all the time for mystical reasons, that
only few wizards pretend to understand.</span></div>

style="mso-ansi-language: EN-GB">Part of this presentation
will be devoted to demystify this process, with the purpose
not to transform you into a wizard, but convince you, that
this is a rational exercise, and with time you would be able
to become a wizard. But you do not have to. Luckily the number
of NSE instruments increased substantially and thanks to
technological developments, and may be to some mental efforts,
their performance did the same, so access to S(q,t) is open to
a wider community with higher precision and higher throughput.
NSE inherently uses polarised neutrons. In the second part of
the presentation, I will go through from simple to more
involved examples, what advantages and disadvantages you might
have. How to approach the interpretation and how best connect
with our beloved S(q,omega) friends. For easier understanding
it might be useful for the audience to review at least partly
