Intrabeam scattering rates and Touschek lifetime appear benign.</td></tr> <tr><td class="formatRecordLabel"> Copyright/License </td><td style="padding-left:5px;">Publication: (License: <a href="http://creativecommons.org/licenses/by/3.0/">CC-BY-3.0</a>)</td></tr> </table> <br/>Corresponding record in: <a href="http://inspirehep.net/record/1743417">Inspire</a> <small> </small> <br/> <br/><br/><div align="right"><div style="padding-bottom:2px;padding-top:30px;"><span class="moreinfo" style="margin-right:10px;"> <a href="" class="moreinfo">Zurück zur Suche</a> </span></div></div> <div class="bottom-left-folded"><div class="recordlastmodifiedbox" style="position:relative;margin-left:1px"> Datensatz erzeugt am 2019-10-22, letzte Änderung am 2020-09-28</div></div> <div class="bottom-right-folded" style="text-align:right;padding-bottom:2px;"> <span class="moreinfo" style="margin-right:10px;"><a href="/search?ln=de&p=recid%3A2695084&rm=wrd" class="moreinfo">Ähnliche Datensätze</a></span></div> </div> </div> </div> <br/> <br /> <div class="detailedrecordminipanel"> <div class="top-left"></div><div class="top-right"></div> <div class="inside"> <div id="detailedrecordminipanelfile" style="width:33%;float:left;text-align:center;margin-top:0"> <div><small class="detailedRecordActions">Fulltext from publisher:</small> <br /><a href="/record/2695084/files/mopmp037.pdf"><img style="border:none" src="/img/file-icon-text-34x48.gif" alt="Volltext herunterladen" /><br />PDF</a><br /></div> </div> <div id="detailedrecordminipanelreview" style="width:30%;float:left;text-align:center"> </div> <div id="detailedrecordminipanelactions" style="width:36%;float:right;text-align:right;"> <ul class="detailedrecordactions"> <li><a href="/yourbaskets/add?ln=de&recid=2695084">Zum persönlichen Korb hinzufügen</a></li> <li>Export als <a style="text-decoration:underline;font-weight:normal" href="/record/2695084/export/hx?ln=de">BibTeX</a>, <a style="text-decoration:underline;font-weight:normal" href="/record/2695084/export/hm?ln=de">MARC</a>, <a style="text-decoration:underline;font-weight:normal" href="/record/2695084/export/xm?ln=de">MARCXML</a>, <a style="text-decoration:underline;font-weight:normal" href="/record/2695084/export/xd?ln=de">DC</a>, <a style="text-decoration:underline;font-weight:normal" href="/record/2695084/export/xe?ln=de">EndNote</a>,  <a style="text-decoration:underline;font-weight:normal" href="/record/2695084/export/xn?ln=de">NLM</a>, <a style="text-decoration:underline;font-weight:normal" href="/record/2695084/export/xw?ln=de">RefWorks</a> </li> </ul> <div style='padding-left: 13px;'>  <div id="bookmark"></div> <div id="bookmark_sciencewise"></div> <style type="text/css"> #bookmark_sciencewise, #bookmark {float: left;} #bookmark_sciencewise li {padding: 2px; width: 25px;} #bookmark_sciencewise ul, #bookmark ul {list-style-image: none;} </style> <script type="text/javascript" src="/js/jquery.bookmark.min.js"></script> <style type="text/css">@import "/css/jquery.bookmark.css";</style> <script type="text/javascript">// <![CDATA[ $.bookmark.addSite('sciencewise', 'ScienceWise.info', 'https://cds.cern.ch/img/sciencewise.png', 'en', 'bookmark', 'http://sciencewise.info/bookmarks/cds:2695084/add'); $('#bookmark_sciencewise').bookmark({sites: ['sciencewise']}); $('#bookmark').bookmark({ sites: ['facebook', 'twitter', 'linkedin', 'google_plusone'], icons: '/img/bookmarks.png', url: 'https://cds.cern.ch/record/2695084', addEmail: true, title: "Updated High-Energy LHC design", description: "We present updated design parameters for a future High-Energy LHC.
