In this context an upgrade of the main accelerating RF system of the Proton Synchrotron (PS) is necessary, aiming at reducing the cavity impedance which is the source of longitudinal coupled-bunch oscillations. These instabilities pose as a major limitation for the increase of the beam intensity as planned after LS2. The 10 MHz RF system consists in 11 ferrite loaded cavities, driven by tube-based power amplifiers for reasons of radiation hardness. The cavity-amplifier system is equipped with a wide-band feedback that reduces the beam induced voltage. A further reduction of the beam loading is foreseen by upgrading the feedback system, which can be reasonably achieved by increasing the loop gain of the existing amplification chain. This paper describes the progress of the design of the upgraded feedback system and shows the results of the tests on the new amplifier prototype, installed in the PS during the 2015-16 technical stop. It also reports the first results of its performance with beam, observed in the beginning of the 2016 run.</span> </td> </tr> <tr class="tablerow"> <td class="fieldkey">Paper</td> <td class="datarow">download <a href="http://jacow.org/ipac2016/papers/mopor013.pdf" target="pdf">MOPOR013.PDF</a> [0.497 MB / 4 pages]</td> </tr> <tr class="tablerow"> <td class="fieldkey">Export</td> <td class="datarow">download ※ <a href="http://jacow.org/ipac2016/export/MOPOR013-bib.htm" target="exp">BibTeX</a> ※ <a href="http://jacow.org/ipac2016/export/MOPOR013-tex.htm" target="exp"> LaTeX</a> ※ <a href="http://jacow.org/ipac2016/export/MOPOR013-txt.htm" target="exp">Text/Word</a> ※ <a href="http://jacow.org/ipac2016/export/MOPOR013-ris.htm" target="exp">RIS</a> ※ <a href="http://jacow.org/ipac2016/export/MOPOR013.xml" target="exp">EndNote</a></td> </tr> <tr class="tablerow"> <td class="fieldgrp">Conference</td> <td class="fieldhigh">IPAC2016, Busan, Korea</td> </tr> <tr class="tablerow"> <td class="fieldkey">Series</td> <td class="datarow">International Particle Accelerator Conference (7th)</td> </tr> <tr class="tablerow"> <td class="fieldkey">Proceedings</td> <td class="datarow">Link to full <a href="http://jacow.org/ipac2016/" target="pdf">IPAC2016 Proccedings</a></td> </tr> <tr class="tablerow"> <td class="fieldkey">Session</td> <td class="datarow">Poster Session</td> </tr> <tr class="tablerow"> <td class="fieldkey">Date</td> <td class="datarow">09-May-16 16:00–18:00</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">T06 Room Temperature RF</td> </tr> <tr class="tablerow"> <td class="fieldkey">Keywords</td> <td class="datarow">cavity, feedback, impedance, network, beam-loading</td> </tr> <tr class="tablerow"> <td class="fieldgrp">Publisher</td> <td class="fieldhigh">JACoW, Geneva, Switzerland</td> </tr> <tr class="tablerow"> <td class="fieldkey">Editors</td> <td class="datarow">Christine Petit-Jean-Genaz (CERN, Geneva, Switzerland); Dong Eon Kim (PAL, Pohang, Republic of Korea); Kyung Sook Kim (PAL, Pohang, Republic of Korea); In Soo Ko (POSTECH, Pohang, Republic of Korea); Volker RW Schaa (GSI, Darmstadt, Germany)</td> </tr> <tr class="tablerow"> <td class="fieldkey">ISBN</td> <td class="datarow">978-3-95450-147-2</td> </tr> <tr class="tablerow"> <td class="fieldkey">Published</td> <td class="datarow">June 2016</td> </tr> <tr class="tablerow"> <td class="fieldkey">Copyright</td> <td class="datarow"> <table> <tr><td>Copyright © 2016 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>
