To enhance the performance of micro-patterned gaseous detectors (MPGDs) to meet the challenging requirements of future HEP experiments, 2D materials are attractive candidates to address the backflow of positive ions (ion backflow, IBF), which affects detector performance by distorting electric field lines. A single or few layers of graphene are promising to...
Hydrogenated nonodiamond grains represent an alternative to CsI for detection of single VUV photons in gaseous detectors. A dedicated R&D study on of nanodiamond photocathodes coupled to THGEM-based photon detectors is ongoing. The first phase of these studies includes the comparison of QE in vacuum and in gaseous atmospheres and measurement of aging effects under irradiation and exposure to...
The study of 2D materials, and in particular their interaction with low-energy electrons, is of great interest in surface physics, as well as in several applications ranging from the development of electronic devices to novel detectors for particle physics. The concept of graphene as a pressure-tight membrane transparent to electrons can be employed for the upgrade of MPGD detectors, like...
Gas Electron Multiplier (GEM) has become a widely employed technology in modern particle and nuclear physics experiments. Despite great advancements in their construction and performance, the formation of electrical discharges remains one of the major factors limiting the long-term stable operation of GEM detectors and it is crucial to develop methods to mitigate them. In this work GEM...
