In WP1, which constituted the foundational phase of the project, the consortium delivered the Technical Design Report on Detectors and Electronics (D1.1) and the Conceptual Design for the DAQ system (D1.2). During this phase, the clinical requirements were successfully translated into precise and quantifiable engineering specifications. Key achievements included the finalisation of the detector geometry, the development of a design concept for high-speed DAQ electronics, and, crucially, the initial beam test results (D1.3). These beam tests validated the feasibility of the selected scintillation candidates and enabled a detailed characterisation of the clinical beam structure at the MIT facility.
In WP2, a comprehensive literature review and a series of meetings with the DKFZ 3D-printing groups were conducted to identify approaches that allow precise control of calcium content while maintaining structural stability. Based on these discussions, patient-like, 3D-printed bone scaffolds were conceptualised for preliminary BoneOscopy experiments under proton irradiation. The key design variables were defined as scaffold structure, porosity, density, and calcium content. The Gammex™ 467 phantom was selected as a reference for the development and validation of calcium quantification methods, as it provides well-characterised inserts with known elemental composition for comparison with the printed bone samples.
In WP3, the consortium finalised the geometry and crystal configuration of the primary detector, leveraging both the simulation and experimental results obtained in Work Package 1.
In WP4, we focused on the design and construction of the trigger detector head. The design activities build directly on the simulation and experimental results obtained in Work Package 1. Ongoing work includes the optimisation of the proposed detector solutions and the execution of initial measurements to validate their performance.
In WP5, the beam application and monitoring system (BAMS) of the Marburg Ion-Beam Therapy Center (MIT) was modelled using the Monte Carlo codes TOPAS and Geant4. The BAMS comprises five monitoring chambers: three ionisation chambers (ICs) used to monitor the particle rate and total particle count, and two multi-wire proportional counters (MWPCs) employed to monitor the beam position and width.
