Description

The Cold molecule Nuclear Time-Reversal EXperiment (CeNTREX) is preparing a search for T-violating interactions by detecting shifts in nuclear magnetic resonance frequencies of $^{205}$Tl nuclei in a cold molecular beam of electrically-polarized TlF molecules. The experiment enhances the statistical sensitivity by first using rotational cooling to increase the molecular population in a single J=0 ground electronic and vibrational state, followed by a transfer the to J=2 level for focusing by an electrostatic lens. Molecules are then transferred to the J=1 level for the Schiff moment measurement. The experimental protocols and progress towards a measurement will be presented.
