The beam-beam effect can have severe repercussions for both the electron and hadron beams in these colliders, and are modeled here using the strong-strong code Guinea-Pig. This work focuses on how the luminosities of the linac-ring designs for both the LHeC and FCC-he react to different waist shifts, bunch charges, and IR beta-functions. Simulations are also performed to measure the emittance growth of the stored hadron beams as they are repeatedly collided with an electron beam that is experiencing an offset jitter. The ramifications for the spent electron beam are also examined. </span></p></div><br><div>Wednesday, April 1, 2015<br></div><div>2:30 p.m.<br></div><div>CEBAF Center Auditorium <br></div><br><br><div><span class="ZmSearchResult" id="DWT1557" data-mce-style="">Seminar</span> archives are found here: <span class="Object" id="OBJ_PREFIX_DWT1558_com_zimbra_url" data-mce-style=""><span class="Object" id="OBJ_PREFIX_DWT2318_com_zimbra_url" data-mce-style=""><span class="Object" id="OBJ_PREFIX_DWT1106_com_zimbra_url" data-mce-style=""><span class="Object" id="OBJ_PREFIX_DWT2067_com_zimbra_url"><a href="http://wwwold.jlab.org/accel/seminars.html" target="_blank" data-mce-style="" data-mce-href="http://wwwold.jlab.org/accel/seminars.html">http://wwwold.jlab.org/accel/seminars.html</a></span></span></span></span><br></div><br><div><div>------<br><b><span style="font-size: small;" data-mce-style="font-size: small;">Audrey N.
