The Atacama Large Millimetre/Sub-millimetre Array presents a completely new opportunity for high resolution observation of solar prominences/filaments in a previously little explored spectral domain. Plasma properties of prominences have been frequently inferred from the study and analysis of spectral lines. These methods, whilst proving very useful, have limitations caused by complex non-LTE radiative transfer in line formation, amongst other effects. Quiet sun millimetre radiation is collisionally formed, therefore leading to an LTE source function that scales linearly with the kinetic temperature of the plasma. ALMA's high spatial resolution thus gives it the potential to directly measure the local temperature of the prominence plasma with unprecedented accuracy. In this poster we shall present results from non-LTE prominence modelling in the millimetre domain as well as preliminary view of prominences/filaments from ALMA science verification data.
