Abstract Hadron therapy is an advanced radiation modality for treating cancer, which currently uses protons and carbon ions. Hadrons allow a highly conformal dose distribution to the tumour, minimising detrimental side-effects due received by healthy tissues. Treatment with hadrons requires sub-millimetre spatial resolution high dosimetric accuracy. This paper discusses design, fabrication performance tests of detector based on Gas Electron Multipliers (GEM) coupled matrix thin-film...
