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 the </span><a
