To satisfy these requirements when post-sample ion detection is not feasible, we constructed a transmission single-ion detector based on an ultra-thin diamond membrane. The negligible intrinsic noise provides an excellent signal-to-noise ratio and enables a hit-detection efficiency of close to 100%, even for energetic protons, while the small thickness of the membrane limits beam spreading. Moreover, because of the superb mechanical stiffness of diamond, this membrane can simultaneously serve as a vacuum window and allow the extraction of an ion microbeam into the atmosphere. %G English %2 https://cea.hal.science/cea-01792091/document %2 https://cea.hal.science/cea-01792091/file/article_VGrilj.pdf %L cea-01792091 %U https://cea.hal.science/cea-01792091 %~ CEA %~ DRT %~ LIST %~ DM2I %~ DIN
