| Περίληψη: | The experimental requirements in existing and envisaged accelerators and experiments have stimulated a great interest in R&D for detectors with high precision timing capabilities; thus, novel instrumentation has emerged. During the R&D phase the timing information is usually extracted from the signal using the full waveform, which is collected with fast oscilloscopes. This is fine for the R&D devices which have a small number of channels, but this method becomes impractical when the detector has many channels because it would produce a large amount of data. In practical applications, the detectors much have a data acquisition implemented in dedicated front-end-electronics which should retain enough information about the signal timing characteristics to allow the arrival time of a particle to be measured with a resolution comparable to the R&D devices. In this work we use novel gaseous detectors and we investigate how we can achieve a timing precision in the of order of 10-ths of picosecond with the use of the leading-edge discrimination timing technique. Even though this method introduces a “time-walk”, which normally affects greatly the timing resolution, we demonstrate how to mitigate the effect of time-walk using two different approaches. The first approach is based on several Time-over-Threshold measurements; the second is based on multiple Charge-over-Threshold information. In this work we prove that these methods are not only feasibility, but they are actually giving a timing resolution which is comparable to that obtained using the full waveforms. In addition, we investigate a one-step estimation of the corrected signal arrival time using artificial Neural Networks with promising results |
