Appearing in the beta decay spectra of mixed Fermi and Gamow Teller transitions, the so-called D correlation is sensitive to Time reversal violation, and via the CPT theorem, to CP violation. CP violation is one of the three famous Sakharov conditions needed for explaining the matter \u2013 antimatter imbalance observed in the Universe [2]. The measurement of the D correlation in the decay of trapped, and laser polarized <sup>23<\/sup>Mg<sup>+<\/sup> and <sup>39<\/sup>Ca<sup>+<\/sup> ions, as proposed in the frame of MORA, complements the search for Electric Dipole Moments to look for new interactions, which can explain the imbalance [3, 4]. The MORA experiment is using an innovative polarization technique, which combines the high efficiency of ion trapping with the one of laser orientation. It is currently taking data using <sup>23<\/sup>Mg<sup>+<\/sup> beams delivered by the IGISOL facility, at the Accelerator Laboratory of the University of Jyv\u00e4skyl\u00e4. A problem of beam contamination by stable <sup>23<\/sup>Na<sup>+<\/sup> has so far hampered the measurement. However, recent experimental progress shows that the laser-polarization proof-of-principle is finally within reach. It enables measurements of D to the ~10<sup>-4<\/sup> level, which will be competitive with the best limit obtained so far on a non-zero D correlation in neutron decay [5]. To attain such precision regime, several weeks of data taking are required along the coming years (2025-2027) at Jyv\u00e4skyl\u00e4, both for <sup>23<\/sup>Mg<sup>+<\/sup> and <sup>39<\/sup>Ca<sup>+<\/sup> beams. As for every precision measurement aiming at looking for New Physics, the analysis of data has to be undertaken in parallel with data acquisition, in order to control data quality and to investigate systematics effects potentially affecting the sensitivity of the measurement. The data analysis includes crosschecks and adaptation of existing simulations of individual detectors of MORA, performed with GEANT4 and PENELOPE Monte Carlo codes, and pursing the investigation of systematic effects using these simulations. Dissemination of the experimental data at national and international conferences will be part of the objectives of the PhD thesis.<\/p><p><span style=\"text-decoration: underline\">Expected skills: <\/span><\/p><p>\u2022 Skills in numerical methods and data analysis, statistics<br \/>\u2022 General interest in developments in fundamental subatomic physics<br \/>\u2022 Knowledgeable in experimental methods in nuclear or particle physics<br \/>\u2022 Good communication skills<br \/>\u2022 Programming (C++\/python\/others)<\/p><p><span style=\"text-decoration: underline\">Contact:<\/span><\/p><p>Pierre Delahaye<br \/>Phone: +33 (0)2 31 45 44 56<br \/>email: pierre.delahaye@ganil.fr<br \/>Address: GANIL, BP 55027, 14076 Caen France<\/p><p><span style=\"text-decoration: underline\">Bibliography<\/span><\/p><p>[1] P.
