Abstract
In our experiments, electrical currents have a range of interest that covers a factor of almost 10^20. Some of these currents need to be measured with part-per-million (ppm) accuracy and others with precision that is limited by particle statistics. It is fair to say that such requirements place exceptional demands on us as experimenters. In this talk I will discuss some methods for measuring electrical currents, in the context of helium scattering experiments. In addition, I will cover tips and tricks to eliminate artifacts; basically, it is all about how to do the job properly.
Series This talk is part of the Surface Physics Seminar series.
