We present a high-flux source of Rb-87 Bose-Einstein condensates combined with a number-resolving detection. The presented techniques offer an exciting path towards the creation and analysis of mesoscopic quantum states with unprecedented fidelities, and their exploitation for fundamental and metrological applications.
