Aims The HASPIDE project wants to explore the possibility to use a:Si-H as a detection material for ioni- zing radiation of different types (photons, electrons, protons, ions, neutrons). Two detection regimes should be tackled: the continuous or pulsed intense radiation flux (e.g., FLASH-RT); the pulse-by-pulse mode, typical of space applications or neutron detection. The material in itself is very radiation-resistant, could be deposited as a thin layer of few micro- meters over many substrates, including flexible ones like Kapton, that potentially opens the way toward many important applications: ionizing radiation flux measurement and dosimetry of charged and photon beams, both clinical and non-clinical ones (accuracy 2% without perturbing the incoming radiation beam); detection of cosmic radiation in the spatial environment; neutron detection after deposition of a thin 10B converter layer.
Methods Some preliminary studies exposing some non-optimized structures either to photon beams, both clinical and laboratory X-rays, and electron clinical beams have already carried out. 50 kVp X-ray tube (0V bias) 6MV photon beam (0V bias) Similar results hold for 6 MeV electrons.
