Description
The Extreme Light Infrastructure - Nuclear Physics (ELI-NP) facility [1] stands at the forefront of cutting-edge research in nuclear physics. Among the innovative projects undertaken at ELI-NP, the development of Thick Gas Electron Multiplier (THGEM) detectors represents a pivotal advancement, particularly for the experimental photo-fission program [2,3]. Fission fragments are ideal for this type of detector as they deposit a large amount of energy leading to massive ionization in the gas volume. Typically, one THGEM is sufficient to generate a large enough signal for the 2D segmented anode readout board. A position resolution of $\approx$ 300 $\mu$m and a time resolution of $\approx$ 700 ps are achieved. A dedicated setup, constructed for testing and optimization of THGEM detectors will be presented. All these results are then used to optimize our modular, in-vacuum capable detectors. The authors would like to acknowledge the support from the ELI-RO-RDI-2024-007 project sponsored by the Romanian Ministry of Research, Innovation and
Digitalisation.
