SCINTI+ Project
The establishment of a working group dedicated to the evaluation and measurement of scintillator properties is being carried out within the framework of the SCINTI+ project (Scintillation Characterization and INtegration for improved Ionizing-radiation metrology), coordinated by B. Sabot and funded by LNE (Laboratoire National de Métrologie et d’Essais) and CEA. This group aims to build shared expertise in the characterization of both commercially available scintillators and materials specifically developed for research and development purposes. The main objective is to create a reference library containing, for each scintillator, a consistent set of experimental and technical data. These data will include, in particular, wavelength emission spectra measured under X-ray excitation, decay-time constants and temporal profiles also obtained under X-ray excitation, light-output non-proportionality curves, pulse shape discrimination — PSD — characteristics, atomic or chemical composition, as well as any other relevant information required to understand the physical and scintillation properties of the material. An important objective will also be to standardize the way these data are reported and formatted, so that they are accessible, comparable and easily usable by the whole community in a clear, understandable and user-friendly format.
This database will also include emerging materials, in particular nanoscintillators, whether studied in solution or embedded in an organic solid matrix. One of the associated objectives is to contribute to the standardization of measurement methodologies for this new class of scintillating materials. Within the scope of Work Package 2 of DRD5 (Detector R&D Collaboration 5, dedicated to quantum sensing for particle physics [1]), this work also aims to present a strategy to rationalize nanoscintillator measurements for the scintillation community. It is also intended to support the establishment of a virtual laboratory based on the contribution of four recognized European laboratories that have agreed to participate in the development of a standardized measurement protocol.
The first results of this work were presented at SCINT 2026 in Korea and are described in a poster available here. The complete dataset is also accessible through this link. This database will therefore support the comparison, selection and optimized use of scintillators for radiation metrology applications by providing users with reliable, traceable and directly exploitable information to identify the materials best suited to specific measurement conditions.
