of up to 50 A and frequencies near 10 kHz. The current amplification is actively stabilized and exhibits fractional current noise better than one part in
.The source was developed for use with an atom interferometer based on
magnetically trapped condensate atoms. The relationship between current noise
and interferometer noise is developed, and it is shown that the demonstrated
precision should permit interferometry with coherence times of 1 s or more.
