The superconducting nanowire single-photon detector (SNSPD), provides single photon sensitivity from visible to mid infrared wavelengths, with recovery times and timing precision orders of magnitude faster than existing single-photon detectors both based on superconducting materials (Transition Edge Sensor, TES) and its semiconductor competitors (Avalanche Photodiode Detectors, APD). In addition, this detector operates at the boiling point of liquid helium (2 - 4 K), a temperature now easily reachable thanks to the rapidly improving closed-cycle cooling technology.....continue....

 

3)      Neutral Particle Analyzer  (NPA) (Mattioli)

Tags: Detectors for aerospace applications: ELENA (Emitted Low-Energy Neutral Atoms) detector

Tags: Experiment SERENA of the ESA/ASI Bepicolombo mission to Mercury

People: A.Gaggero, F.Mattioli and R.Leoni

The neutral sensor ELENA (Emitted Low-Energy Neutral Atoms) for the ESA cornerstone BepiColombo mission to Mercury (in the SERENA instrument package) is a new kind of low energetic neutral atoms instrument, mostly devoted to sputtering emission from planetary surfaces, from E < 30 eV up to E~5 keV. This kind of ToF  system is able to directly  measure low-energy neutral atoms identifying Tstart and Tstop by means of a Start element (the Shuttering nanofabricated System) and the Stop element (a MCP detector). The incoming neutral particles hence pass through the entrance with a definite timing (START) and arrive to a STOP detector after a flight path....continue..
