Dear Yangkang Wu,
<div class=""><br class="">
<div class=""><br class="">
</div>
<div class="">Thank you for reaching out about your McXtrace 1.7 issues.</div>
<div class=""><br class="">
</div>
<div class=""><br class="">
</div>
<div class="">In regard to your compilation-issue with Mirror_elliptic.comp you are completely right, the version shipped with v. 1.7 contained errors. </div>
<div class=""><br class="">
</div>
<div class="">The component has already been corrected by Antoine Pado from SOLEIL. You may download the updated component via this link:</div>
<div class=""><a href="https://raw.githubusercontent.com/McStasMcXtrace/McCode/master/mcxtrace-comps/optics/Mirror_elliptic.comp" class="">https://raw.githubusercontent.com/McStasMcXtrace/McCode/master/mcxtrace-comps/optics/Mirror_elliptic.comp</a></div>
<div class=""><br class="">
</div>
<div class=""><br class="">
</div>
<div class="">In regard to your issue with Mirror_curved I am not completely convinced there is a problem, but will of course investigate further. </div>
<div class="">In the meantime, please study how the component is used in the example instruments of your McXtrace 1.7 version. The mirror is in use in several instrument models:</div>
<div class=""><br class="">
</div>
<div class="">JJ_SAXS.instr<br class="">
MAXII_711.instr<br class="">
MAXII_811.instr<br class="">
MAXIV_Bloch.instr<br class="">
MAXIV_FemtoMAX.instr<br class="">
SOLEIL_ROCK.instr<br class="">
XFEL_SPB.instr</div>
<div class=""><br class="">
</div>
<div class="">In XFEL_SPB.instr Mirror_curved is used in a Kirkpatrick-Baez geometry and seems to work as expected. </div>
<div class=""><br class="">
</div>
<div class="">Best regards,</div>
<div class="">Peter Willendrup</div>
