Dr. Nappi is staff at INFN as director of research. He has almost forty years of experience in many areas of high-energy physics projects, from detector design and construction to physics data analyses. In the course of his career, he has gained a large competence in the development of new detectors. Among his achievements, he made substantial contributions to cutting-edge technologies that are of central importance for the sustainable development of particle identification detectors (TOF, Cherenkov and transition radiation detectors). In particular, he produced notable results in the development of innovative imaging Cherenkov counters, which gained him international recognition.

Development of solid photocathodes for gaseous detectors

The underlying physical process and the operating principle of gas filled devices equipped with solid photocathodes will be outlined together with their feature of detecting single photons with high efficiency and position resolution.

The new trends and developments to overcome the relevant issues and present limitations in the field will also be described in this tutorial.
