Our theoretical and experimental results show that, by controlling the system's parameters, we can engineer the escape rate of a Bose-Einstein condensate to an exceptional degree. Possible applications of this atom-optics realization of the open Wannier-Stark system are discussed.6 pp, proceedings DICE 11-15 September 2006, Castello di Piombino, Tuscany, ItalyOther Condensed Mattertext
