Timing in scientific experiments
Javier Serrano, CERN
Abstract: Historically, our ability to measure time and its inverse, frequency, has greatly benefited from scientific advances. In fact, if one looks at the latest generation of high-precision clocks, they appear very much like other complex scientific experimental setups. So science helps timing, that's well known. But how does timing help science? In this talk, I will go through a number of scientific experiments of different kinds. For each type of experiment, I will provide a quick introduction and some context to appreciate its scientific relevance, and then focus on the role of timing and synchronization subsystems within the experiment. Along the way, we will see the different techniques used in timing systems to cope with the widely varying constraints in factors such as accuracy, precision and geographic distribution.
