Sub-picosecond event timing - New techniques and first results
Original language description
We are presenting the novel time interval measurement device, which is based on a surface acoustic wave (SAW) filter as a time interpolator. The operating principle is based on the fact that a transversal SAW filter excited by a short pulse can generatea finite signal with highly suppressed spectra outside a narrow frequency band. If the responses to two excitations are sampled at clock ticks, they can be precisely reconstructed from a finite number of samples and then compared so as to determine the time interval between the two excitations. The temperature drift of the measured time interval on temperature is lower than 0.5 ps/K and the long term stability is better than +/- 0.2 ps per hour.These are to our knowledge the best values reported for thetime interval measurement device. The first SLR results based on this timing will be presented.
