Analysis on the noise sources in data-acquisition system

摘要

Noises in data-acquisition system may affect the data and experiment results, so it is of vital importance to find noise sources and deal with them immediately. Adopting experiment data, this article begins with research on the single-channel counting rate of the detector. With data-acquisition system and through calculating the cross talking of the strip pattern, as well as the counting rate of detector and strip, the author can analyze sources of noises accurately, so as to deal with them. This kind of analysis can be adopted as a detecting standard to test the stability of the array for a long run.
