Exploring Multidimensional Parameter Space for THGEM Technology Development

This dissemination material showcases the exploration of a multiparameter space for THGEMs (THick Gas Electron Multipliers), focusing on geometric parameters such as diameter, pitch, rim thickness, material properties, and production procedures. Key configurations include R3 and W2 designs with specified dimensions, aimed at enhancing the efficiency of photon detectors. The study investigates the effective gain of the THGEMs and introduces innovative photon converters using multiwall carbon nanotubes. TEM and SEM imaging provide essential insights into the structural integrity of the materials used.
