<div dir="auto">I certainly think looking at your Option B would help reduce the burden on the splitters without adding nonlinear magnets. If it also helps the match conditions, all the better!

<pre class="blue">I wonder what would happen if you allowed permanent magnets in the splitter lines. For example the sort of FDFDF "complex bend" Dejan was showing a picture of could allow bending without the dispersion getting too high.<br><br>The thing I think might be hard to solve that way is R56 (TOF is OK overall because separate lines).<br><br>I should mention I had an alternative lattice "B" in my IPAC24 paper that reduced the TOF and R56 by over a factor of two from the baseline, even with linear magnets, by using a slightly shorter cell. One of the nonlinear field solutions does even better even with a long cell. We could try and optimise a cell with the smallest TOF variation if that would help in the splitters.<br><br> -Stephen<br><br><hr><br>From: FFA_CEBAF_Collab <ffa_cebaf_collab-bounces@jlab.org> on behalf of Ryan Bodenstein via FFA_CEBAF_Collab <ffa_cebaf_collab@jlab.org><br>Sent: 01 November 2024 12:21<br>To: Alex Bogacz via FFA_CEBAF_Collab<br>Subject: Re: [FFA_CEBAF_Collab] FFA@CEBAF WG mtg. this Friday, November 1<br><br>Good afternoon, Colleagues!<br><br>Attached, you'll find our minutes (as well as uploaded).<br><br>You all have a great weekend!<br>Ryan<br><br><br><br>Dr. Ryan Bodenstein (he/him)<br><br>Staff Scientist II – Center for Advanced Studies of Accelerators (CASA)<br><br>[signature_2397784822]<br><br>12000 Jefferson Avenue<br><br>Newport News, VA 23606<br><br>United States of America<br><br><hr><br>From: FFA_CEBAF_Collab <ffa_cebaf_collab-bounces@jlab.org> on behalf of Alex Bogacz via FFA_CEBAF_Collab <ffa_cebaf_collab@jlab.org><br>Sent: Monday, October 28, 2024 5:38 PM<br>To: Alex Bogacz via FFA_CEBAF_Collab <ffa_cebaf_collab@jlab.org><br>Subject: [FFA_CEBAF_Collab] FFA@CEBAF WG mtg. this Friday, November 1<br><br><br><br>Dear Colleagues,<br><br>We will continue our design efforts this Friday, November 1, at 11:00 am.<br><br> * Emittance budget update - Kirsten<br> * ‘White Paper’ on 22 GeV CEBAF - ALL<br> * AOB - ALL<br><br>Please, follow a ZOOM invitation below.<br><br>Cheers,<br><br>Alex<br><br><hr><br><br>S.
