To ensure accurate particle-specific response, a comprehensive characterization of SSNTDs and their associated track features is required. This involves systematic evaluation of detector surface quality, track registration efficiency across different particle types, detection thresholds, angular dependence of track sensitivity, and spectroscopic resolution. In this study, experimental investigations will be carried out using both a 3 MV Tandetron accelerator and the Extreme Light Infrastructure - Nuclear Physics (ELI-NP) facility. The methodology includes deploying SSNTDs in arrays designed to achieve varying incidence angles. Detector stacks, each consisting of two SSNTD layers, will be irradiated at four selected dip angles (δ = 90o, 60o, 45o, 30o). This approach enables correction for solid-angle effects and critical angle sensitivity in track registration. The outcomes of this project are expected to improve dose estimation protocols in radiation protection laboratories and, more importantly, to provide refined tools for the study of biological systems exposed to proton beams. Objectives: - Validation of proton beam models and methodologies through the use of traceable beam measurements, supported by complementary dosimetric and spectrometric analyses (Objectives 1 & 2). - Development of harmonized measurement capabilities to ensure consistency and comparability across existing experimental and analytical approaches (Objective 3). - Establishment of a standardized protocol for the application of the developed methodology, enabling reliable calculation of absorbed and equivalent doses (Objective 4). - Provision of traceable measurement methods for exposure assessment across different beam types and energies, thereby generating reference data to strengthen radiation protection frameworks and international dosimetry networks (Objective 5).
