Dear all,
<div class=""><br class="">
</div>
<div class=""><br class="">
</div>
<div class="">Jan Saroun from NPI in Czech Republic (and author of RESTRAX/SIMRES) has spotted an unfortunate error in the ESS_moderator.comp component, relating to the 2014 "pancake" case.<br class="">
<br class="">
The bug is a missing distance-factor in a solid-angle computation and will lead to a too high brilliance emitted from the source.<br class="">
<br class="">
Unfortunately was never spotted in our tests since these happen with an instrument where this distance is set to 1 m... (and 1 x 1 = 1... )<br class="">
<br class="">
The updated source packge for use with McStas 1.12c and 2.x is available for download at <a href="http://mcstas.org/download/share/ESS_moderator_February_2015.tgz" class="">http://mcstas.org/download/share/ESS_moderator_February_2015.tgz</a> . A set of “release
notes” is available at <a href="http://mcstas.org/download/share/ESS_moderator_February_2015.tgz.html" class="">http://mcstas.org/download/share/ESS_moderator_February_2015.tgz.html</a></div>
