Description
The HASPIDE project, funded by INFN, focuses on the development of hydrogenated amorphous silicon (a-Si:H) detectors for applications in X-ray dosimetry. These devices are fabricated on thin Kapton substrates, combining good mechanical flexibility with promising dosimetric performance. The control over the deposition process and the integration on flexible supports make this technology particularly suitable for in vivo and superficial dose measurements.
In this contribution, I will present an overview of the detector design and the latest results obtained from characterization campaigns carried out with different X-ray sources — including clinical beams, laboratory setups, and synchrotron radiation. Measurements have focused on evaluating dose linearity, sensitivity, and response stability under various irradiation conditions, with particular attention to applications such as microbeam radiation therapy (MRT) and standard radiotherapy settings.
The preliminary results confirm the potential of a-Si:H technology as a flexible and versatile solution for precise X-ray beam characterization, both in clinical and research contexts, opening up interesting perspectives for future developments.
