  MeerKAT imaging of the globular cluster 47 Tucanae (47 Tuc) reveals 1.28 GHz
continuum emission at the locations of 20 known millisecond pulsars (MSPs). We
use time series and spectral imaging to investigate the image-domain
characteristics of the MSPs, and search for previously unknown sources of
interest. The MSPs exhibit a range of differences in their temporal and
spectral properties compared the general background radio source population.
Temporal variability differs strongly from pulsar to pulsar, some appearing to
vary randomly on 15 min timescales, others varying coherently by factors of >10
on timescales of hours. The error in the typical power law fit to the spectrum
emerges as a powerful parameter for indentifying the MSPs. This behaviour is
likely due to differing diffractive scintillation conditions along the sight
lines to the MSPs. One MSP exhibits tentative periodic variations that are
consistent with modulation due the orbit of an eclipsing binary system. One
radio source has spectro-temporal properites closely resembling those of the
MSP population in the cluster, and we report its position as a candidate new
MSP, or alternatively an interferometric localisation of one of six MSPs which
do not yet have an accurate position from the timing solutions.
