Cilento <br> European Organization for Nuclear Research</ul><tr class=doi-abstract><th>Abstract<td>Proposals to measure a possible Electric Dipole Moment (EDM) of protons in an electro-static machine are studied by a world-wide community. The machine is operated at the so-called magic energy to satisfy the "frozen spin" condition such that, without imperfections and the well-known magnetic moment of the particle, the spin is always oriented parallel or antiparallel to the direction of movement. The effect of a finite EDM is a build-up of a vertical spin component. A small average radial magnetic field leads as well to a build-up of a vertical spin component, which cannot be disentangled from the effect due to a finite EDM, and thus generates a systematic error of the measurement. Essential ingredients of the concept are to install the machine inside a state-of-the-art magnetic shielding and to measure the vertical orbit separation of two counter-rotating beams, enhanced by choosing a very low vertical tune, with high precision pick-ups. In this paper, we analyse limitations of this method and, in particular, the impact of wanted ("strong focusing" lattice) and unwanted variations of the betatron functions and of coupling.<tr class=doi-paper><th>Paper<td>download: <a data-href=pdf/WEPL027.pdf download href=javascript:void(0); onclick=openUrl(`pdf/WEPL027.pdf`)>WEPL027.pdf</a><tr class=doi-cite><th>Cite<td><a data-href=reference/wepl027-bibtex/index.html href=javascript:void(0); onclick=openUrl(`reference/wepl027-bibtex/index.html`)>BibTeX</a>, <a data-href=reference/wepl027-latex/index.html href=javascript:void(0); onclick=openUrl(`reference/wepl027-latex/index.html`)>LaTeX</a>, <a data-href=reference/wepl027-word/index.html href=javascript:void(0); onclick=openUrl(`reference/wepl027-word/index.html`)>Text/Word</a>, <a data-href=reference/wepl027-ris/index.html href=javascript:void(0); onclick=openUrl(`reference/wepl027-ris/index.html`)>RIS</a>, <a data-href=reference/wepl027-endnote/index.html href=javascript:void(0); onclick=openUrl(`reference/wepl027-endnote/index.html`)>EndNote</a><tr class=doi-conference><th>Conference<td>14th International Particle Accelerator Conference<tr class=doi-series><th>Series<td><tr class=doi-location><th>Location<td>Venice, Italy<tr class=doi-date><th>Date<td>07-12 May 2023<tr class=doi-publisher><th>Publisher<td>JACoW Publishing, Geneva, Switzerland<tr class=doi-editorial-board><th>Editorial Board<td>Ralph Assmann - Deutsches Elektronen-Synchrotron DESY Peter McIntosh - Science and Technology Facilities Council (STFC/DL/ASTeC) Giovanni Bisoffi - Istituto Nazionale di Fisica Nucleare (INFN/LNL) Alessandro Fabris - Elettra-Sincrotrone Trieste S.C.p.A.
