Thanks Ryan!
<div>This will give us a good idea about the required aperture of the middle magnets of the FFA branch chicane <span style="font-family: Calibri, sans-serif; font-size: 11pt;">(passes 9-19). </span></div>
<div>Have a great weekend.</div>

<p class="MsoNormal">Good evening colleagues,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">As a quick follow up to our meeting, I’m sending out two plots in answer to questions of the spread of the orbits in the FFA branch of our spreader.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">One is a plot of *<b>all</b>* elevations for the different passes in the NE spreader. Please recall, passes 1-7 are EM passes, and 9+ are all in the FFA branch.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The second plot is simply focusing on the FFA branch (passes 9-19). As expected, they scale like the dispersion. To simulation accuracy, the full width of the spread is 10032.372 - 10015.834 = 16.583 cm. So, it’ll be a big (rectangular?)
beampipe, but I think that was expected by all of us.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Just wanted to send that out before everyone got off for the weekend. Speaking of which, have a wonderful one!<o:p></o:p></p>
