H Moskov,<br>
<br>
I did some fast crewed simulation and find that a 150MeV/ K+ will
never be detected<br>
in the GlueX detector. It is simply not possible. The K+ decays even
before reaching the <br>
Start Counter.<br>
<br>
In order for a K+ to be detected and tracked it needs a momentum of
about 250MeV/c<br>
at the minimum.<br>
<br>
you can find the necessary information in the attached pdf file.<br>
<br>
cheers,<br>
Beni<br>
