  In order to achieve higher resolutions the next generation of accelerator facilities is designed to operate with beam powers orders of magnitude higher than that handled by the current technology. So it is believed that the existing target and beam dump designs will be unsuitable to survive beam interactions depositing powers in the order of several megawatts. Good target design is important for the physics yield from experiments and crucial to the reliable operation of the facility. Furthermore the choice of target is strongly associated with the safety and cost of design (i.e., economic viability) of the entire facility. This article proposes a new target technology based on fluidised powder believed to be suitable for application at higher beam powers whilst avoiding some of the problems associated with other technologies. A conceptual system design for the application of the fluidised powder target to the requirements of a future neutrino facility, is presented. The preliminary experimental results presented, show the effect of some of the parameters which are expected to determine the performance, physics yields and reliability of operation of the new powder system.
