  We present the polarization profiles of 22 pulsars in the globular cluster 47
Tucanae using observations from the MeerKAT radio telescope at UHF-band
(544-1088 MHz) and report precise values of dispersion measure (DM) and
rotation measure (RM). We use these measurements to investigate the presence of
turbulence in electron density and magnetic fields. The structure function of
DM shows a break at $\sim 30$ arcsec ($\sim 0.6$ pc at the distance of 47
Tucanae) that suggests the presence of turbulence in the gas in the cluster
driven by the motion of wind-shedding stars. On the other hand, the structure
function of RM does not show evidence of a break. This non-detection could be
explained either by the limited number of pulsars or by the effects of the
intervening gas in the Galaxy along the line of sight. Future pulsar
discoveries in the cluster could help confirm the presence and localise the
turbulence.
