  Bose-Einstein condensates (BECs) of neutral atoms constitute an important
quantum system for fundamental research and precision metrology. Many
applications require short preparation times of BECs, for example, for
optimized data acquisition rates in scientific applications, and reduced dead
times and improved bandwidths for atomic quantum sensors. Here, we report on
the generation of rubidium BECs with a repetition rate of more than 2 Hz. The
system relies on forced evaporation in a dynamically adjusted optical
potential, which is created by the spatial modulation of laser beams. Our
system provides a versatile source of the ubiquitous rubidium BECs, and
promotes their exploitation for high-precision atom interferometers.
