Abstract

We present an experimental apparatus that produces Bose-Einstein condensates (BECs) of 87^{87}Rb atoms at a rate of 1 Hz. As a demonstration of the system's ability to operate continuously, 30 BECs were produced and imaged in 32.1 s. Without imaging, a single BEC could be produced in 953 ms. The system uses an atom chip to confine atoms in a dimple trap with frequencies exceeding 1 kHz. With this tight trap, the duration of evaporative cooling was reduced to less than 0.5 s. Using principal component analysis, insight into the largest sources of noise and drift was obtained by extracting the dominant contributions to the variance. The system utilizes a compact physics package that can be integrated with lasers and electronics to create a transportable ultracold-atom device for applications outside of a laboratory environment.
