Hi Moskov,<br>
<br>
my response to this is the following:<br>
lets take a K+ at 150MeV/c going out at close to 60 degree.<br>
This K+ my need to pass through a substantial amount of liquid
hydrogen<br>
depending on where it is generated in the target. This can be
between zero<br>
and 7cm. After that it has to pass tough the target cell the
scattering chamber<br>
and then through the start counter in order to get to the CDC and
produce a track.<br>
<br>
so <br>
a) what is the likelihood that a 150MeV/c K+ makes it to the Start
counter?<br>
b) how much energy is deposited in the start counter?<br>
c) what is the likelihood that this K+ will generate enough hits in
the CDC to reconstruct a track?<br>
d) There will be only 1 track at best, how can this event be
reconstructed with this limited<br>
since the vertex is not very well defined?<br>
<br>
cheers,<br>
Beni<br>
