  2. ELENA is a Time-of-Flight (ToF) sensor, based on the state-of-the art of ultra-sonic oscillating shutter (operated at frequencies of the order of tens of kHz), mechanical gratings and Micro-Channel Plate (MCP) detectors. The purpose of the shuttering system is to digitize space and time when tagging the incoming particles without introducing “disturbing” detec­tor elements, which may affect the particle’s trajectory or the energy. This is particularly important in this case, in which neutrals of energies of a few tens of eVs must be detected. Soft X-rayshuttering @43kHz Ion beam_1keV shuttering @43kHz

  3. Crucial ELENA elements Crucial elements to reach the requested performances for TOF ELENA instrument are: the Start element : Shutter System the Stop element : MCP detector (efficiency for low energy particles) → these two challenging items are the actual objects of our laboratory activity because they need to be tested with particle beam HEWG Meeting, Key Largo, May 14-17, 2013
