چکیده انگلیسی
This article presents a detector system consisting of three components, a CMOS imaging array, a gaseous-detector structure with a Micromegas layout, and a UV-photon sensitive CsI reflective photocathode. All three elements have been monolithically integrated using simple post-processing steps. The Micromegas structure and the CMOS imaging chip are not impacted by the CsI deposition. The detector operated reliably in He/isobutane mixtures and attained charge gains with single photons up to a level of 6Ã104. The Timepix CMOS array permitted high resolution imaging of single UV-photons. The system has an MTF50 of 0.4Â lp/pixel which corresponds to approximately 7Â lp/mm.
