Description
Architectures based on multiple layers of THick-Gas Electron Multipliers (THGEM) represent a possible answer to the quest for novel gaseous counters with single photon detection capability able to overcome all the limitations of the present generation of gaseous photon detectors.
A systematic R&D programme has been performed to achieve a deep understanding of the THGEM characteristics and to optimise their parameters in view of the photon detection application. Recently a new hybrid approach has been considered: an architecture where the last multiplication stage is obtained by using a Micromegas stage.
The R&D studies are summarised and some preliminary results obtained with the hybrid architecture prototypes are reported.
