Description
The MORA experiment is looking for a signature of CP violation in the nuclear beta decay of trapped and laser polarised ions [1]. The polarisation technique is more efficient than traditional atom trapping techniques by several orders of magnitude, as recently demonstrated on line at IGISOL, in the university of Jyväskylä, Finland [2, 3]. This technique could ultimately enable the delivery of polarised radioactive ion beams to the DESIR hall once MORA returns to GANIL.
This contribution will describe the latest results with the MORA experiment for the polarisation of 23Mg+ beams, and will explore future opportunities for deploying this technique in polarised radioactive ion-beam experiments beyond MORA.
The MORA project is coordinated by GANIL and brings together a consortium including GANIL, LPC Caen, the University of Jyväskylä, and KU Leuven.
It is supported by ANR under contract ANR-25-CE31-4222.
