Description
Precise measurement of the time of arrival of ionizing particles can be useful in High Energy Physics experiments, for example in high pile-up environments (4D tracking), like for the future generations of colliders, or for particle identification using the time of flight. More precise detectors are also useful outside the HEP community, for instance to increase the accuracy of PET, reducing at the same time the exposure of the patients. The technologies for timing can be categorized in: solid state detectors, i.e. silicon or diamond sensors; gas detectors, and Cherenkov light detectors. The read-out electronics needs to be optimized for timing and the arrival time can be computed using different approaches: a discriminator and a TDC or sampling the signal and using digital analysis. The latter has recently become possible also for integrated and low power systems thanks to the development of fast sampling devices, i.e. SAMPIC, PSEC, etc. Finally, the challenges of the integration of a timing detector in an LHC experiment will be discussed.
