The standard manufacturing tech-nique was to machine the inner and outer conductor sepa-rately, to shrink-fit the 2 pieces and to apply an electron beam welding at the interface. Due to渭cracks, ob-served on some of the cavities around the welds, we took the decision to explore the possibility of a seamless de-sign. First cavities became available in late 2017 and were then cold-tested in the vertical cryostat. These seam-less coated quarter wave resonators have shown some of the highest Q-values of all HIE-ISOLDE cavities in the acceptance tests. Furthermore, we studied the cavity per-formance with different compensations of the earth mag-netic field and different temperature gradients upon cool down. These tests have demonstrated record-breaking RF surface fields for the Nb/Cu technology. This paper re-views the design and fabrication and reports on the cold tests results of seamless quarter wave resonators, and of possible future applications</span> </td> </tr> <tr class="tablerow"> <td class="fieldkey">Paper</td> <td class="datarow">download <a href="http://jacow.org/linac2018/papers/tu1a05.pdf" target="pdf">TU1A05.PDF</a> [0.729 MB / 5 pages]</td> </tr> <tr class="tablerow"> <td class="fieldkey">Slides</td> <td class="datarow">download <a href="http://jacow.org/linac2018/talks/tu1a05_talk.pdf" target="pdf">TU1A05_TALK.PDF</a> [30.518 MB]</td> </tr> <tr class="tablerow"> <td class="fieldkey">Export</td> <td class="datarow">download ※ <a href="../export/TU1A05-bib.htm" target="exp">BibTeX</a> ※ <a href="../export/TU1A05-tex.htm" target="exp"> LaTeX</a> ※ <a href="../export/TU1A05-txt.htm" target="exp">Text/Word</a> ※ <a href="../export/TU1A05-ris.htm" target="exp">RIS</a> ※ <a href="../export/TU1A05.xml" target="exp">EndNote</a></td> </tr> <tr class="tablerow"> <td class="fieldgrp">Conference</td> <td class="fieldhigh"><a href="http://jacow.org/linac2018/" target="pdf">LINAC2018</a></td> </tr> <tr class="tablerow"> <td class="fieldkey">Series</td> <td class="datarow">Linear Accelerator Conference (29th)</td> </tr> <tr class="tablerow"> <td class="fieldkey">Location</td> <td class="datarow">Beijing, China</td> </tr> <tr class="tablerow"> <td class="fieldkey">Date</td> <td class="datarow">16-21 September 2018</td> </tr> <tr class="tablerow"> <td class="fieldgrp">Publisher</td> <td class="fieldhigh"><a href="http://jacow.org" target="pdf">JACoW Publishing, Geneva, Switzerland</a></td> </tr> <tr class="tablerow"> <td class="fieldkey">Editorial Board</td> <td class="datarow">Guoxi Pei (IHEP, Beijing, China); Volker RW Schaa (GSI, Darmstadt, Germany); Yong Ho Chin (KEK, Tsukuba, Japan); Shinian Fu (IHEP, Beijing, China); Ning Zhao (IHEP, Beijing, China)</td> </tr> <tr class="tablerow"> <td class="fieldkey" nowrap>Online ISBN</td> <td class="datarow">978-3-95450-194-6</td> </tr> <tr class="tablerow"> <td class="fieldkey" nowrap>Online ISSN</td> <td class="datarow">2226-0366</td> </tr> <tr class="tablerow"> <td class="fieldkey">Received</td> <td class="datarow">11 September 2018</td> </tr> <tr class="tablerow"> <td class="fieldkey">Accepted</td> <td class="datarow">08 October 2018</td> </tr> <tr class="tablerow"> <td class="fieldkey">Issue Date</td> <td class="datarow">18 January 2019</td> </tr> <tr class="tablerow"> <td class="fieldkey">DOI</td> <td class="datarow"><span style="font-family:Liberation Mono; font-size:12pt;">doi:10.18429/JACoW-LINAC2018-TU1A05</span></td> </tr> <tr class="tablerow"> <td class="fieldkey">Copyright</td> <td class="datarow"> <table> <tr><td><span class="abstract hyphenate jtext" lang="en"><a href="https://creativecommons.org/licenses/by/3.0/"><img alt="Creative Commons CC logo" src="../im0ges/cc.png" style="float: left; margin: 10px" height="30"></a><i>Published by JACoW Publishing under the terms of the <a href="https://creativecommons.org/licenses/by/3.0/">Creative Commons Attribution 3.0 International</a> license.
