<div>Thanks.</div>

<p class="MsoNormal">G’morning Colleagues, and Happy Monday!<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have just uploaded some files for the NE Spreader to the file repository. They are in the Optics folder, in a new folder titles “Spreader.” This link should work as well:
<a href="https://jeffersonlab-my.sharepoint.com/:f:/r/personal/tristan_jlab_org/Documents/Grad%20Student%202019/Graduate%20Student%20Steering/CEBAF%20FFA%20Working%20Group/Optics/Spreader?csf=1&web=1&e=wAZhqJ">
Spreader</a>. But if the link doesn’t work, please just check the repository.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">A few notes:<o:p></o:p></p>
<ol style="margin-top:0in" start="1" type="1">
<li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1">These are all 4 of the EM spreaders for the NE corner. I haven’t done the FFA part yet (and will likely bother Scott a bit to do that part, since I have to know a bit of what requirements
the splitter(s) will have).<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1">These were performed in OptiM, and the conversion to MadX seems to have some odd hiccup (and therefore the conversion to BMAD as well). I’m working on that. For now, I’ve also uploaded
the OptiMX installer for Windows (or Wine/Windows environment that you use). That way, you can run them as you wish, if you wish. But, I also put some .dat files in a subfolder that have some of the info you may need. If you need other info, let me know.<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1">I’m still working on some other options as well. I’d like to drop the height of the first step in the first pass if possible, but I have to check clearances first. I also need to make
sure the setup still fits in the z direction, but I think it does. For now, let’s call this Option 1, tentatively. There will be more, but this should give us a good enough place to work from.<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1">The optics will end up different, depending on what comes out of our linac choice(s). But for now, this is a good approximation. I focused mainly on closing the dispersion and dispersion’,
and just got the betas to be reasonable, but not matched to any specific value. None of the magnets are maxed out (Jay – feel free to correct me if I’m wrong there!), so there should still be some flexibility built in.<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1">For now (relevant to the JLab folks who know our system), don’t assume the names of the magnets are correct. I iterated magnet names in my own way, and some of them don’t reflect the
names of a real magnet. It was for my own book keeping.<o:p></o:p></li></ol>
