A few more details of the after pulsing using the above slides.
... The next slide shows the prompt pulse and the after pulse at a lower rate. As we lowered the rate we found the after pulse was smaller and also wider. I don’t know why but it did seem that at low pulse rates we saw a good deal of single photon noise rather than a definite pulse. Thus I characterize ...

Josephson voltage standard
A Josephson voltage standard is a complex system that uses a superconductive integrated circuit chip operating at 4 K to generate stable voltages that depend only on an applied frequency and fundamental constants. It is an intrinsic standard in the sense that it does not depend on any physical artifact. It is the most accurate method to generate or measure voltage and, by international agreement, is the basis for voltage standards around the World.
