These kickers are often ferrite loaded transmission line type magnets with a rectangular shaped aperture through which the beam passes. The interaction of the beam with the resistive part of the longitudinal beam coupling impedance leads to power dissipation and heating of different elements in the accelerator ring. In particular, power deposition in the kicker magnets can be a limitation: if the temperature of the ferrite yoke exceeds the Curie temperature, the beam will not be properly deflected. In addition, the imaginary portion of the beam coupling impedance contributes to beam instabilities. A good knowledge of electromagnetic properties of materials up to GHz frequency range is essential for a correct impedance evaluation. This paper presents the results of transmission line measurements of complex initial permeability and permittivity for different ferrite types. We present an approach for deriving electromagnetic properties as a function of both frequency and temperature; this information is required for simulating ferrite behaviour under realistic operating conditions.</span> </td> </tr> <tr class="tablerow"> <td class="fieldkey">Paper</td> <td class="datarow">download <a href="http://jacow.org/ipac2018/papers/wepmf089.pdf" target="pdf">WEPMF089.PDF</a> [1.877 MB / 4 pages]</td> </tr> <tr class="tablerow"> <td class="fieldkey">Export</td> <td class="datarow">download ※ <a href="../export/WEPMF089-bib.htm" target="exp">BibTeX</a> ※ <a href="../export/WEPMF089-tex.htm" target="exp"> LaTeX</a> ※ <a href="../export/WEPMF089-txt.htm" target="exp">Text/Word</a> ※ <a href="../export/WEPMF089-ris.htm" target="exp">RIS</a> ※ <a href="../export/WEPMF089.xml" target="exp">EndNote</a></td> </tr> <tr class="tablerow"> <td class="fieldgrp">Conference</td> <td class="fieldhigh">IPAC2018, Vancouver, BC, Canada</td> </tr> <tr class="tablerow"> <td class="fieldkey">Series</td> <td class="datarow">International Particle Accelerator Conference (9th)</td> </tr> <tr class="tablerow"> <td class="fieldkey">Proceedings</td> <td class="datarow">Link to full <a href="http://jacow.org/ipac2018/" target="pdf">IPAC2018 Proccedings</a></td> </tr> <tr class="tablerow"> <td class="fieldkey">Session</td> <td class="datarow">MC7 Poster Session</td> </tr> <tr class="tablerow"> <td class="fieldkey">Date</td> <td class="datarow">02-May-18 16:00–17:30</td> </tr> <tr class="tablerow"> <td class="fieldkey">Main Classification</td> <td class="datarow">07 Accelerator Technology</td> </tr> <tr class="tablerow"> <td class="fieldkey">Sub Classification</td> <td class="datarow">T16 Pulsed Power Technology</td> </tr> <tr class="tablerow"> <td class="fieldkey">Keywords</td> <td class="datarow">kicker, impedance, injection, coupling, simulation</td> </tr> <tr class="tablerow"> <td class="fieldgrp">Publisher</td> <td class="fieldhigh">JACoW Publishing, Geneva, Switzerland</td> </tr> <tr class="tablerow"> <td class="fieldkey">Editors</td> <td class="datarow">Shane Koscielniak (TRIUMF, Vancouver, BC, Canada); Todd Satogata (JLab, Newport News, VA, USA); Volker RW Schaa (GSI, Darmstadt, Germany); Jana Thomson (TRIUMF, Vancouver, BC, Canada)</td> </tr> <tr class="tablerow"> <td class="fieldkey">ISBN</td> <td class="datarow">978-3-95450-184-7</td> </tr> <tr class="tablerow"> <td class="fieldkey">Published</td> <td class="datarow">June 2018</td> </tr> <tr class="tablerow"> <td class="fieldkey">Copyright</td> <td class="datarow"> <table> <tr><td>Copyright © 2018 by JACoW, Geneva, Switzerland</td><td> </td> <td rowspan="2"><img src="../im0ges/ccby-88x31.png" width="88" height="31" alt="CC-BY Creative Commons License" /></td> </tr> <tr><td>cc <a href="https://creativecommons.org/licenses/by/3.0/">Creative Commons Attribution 3.0</a></td><td> </td> </tr> </table> </td> </table> </div> </body> </html>
