Presentation Transcript

  1. Muon detection, towardssocietal applications of MPGD • Thanks to organizers and city mayor! Sébastien Procureur

  2. Features of cosmic muons • Free (already a good point at that time) • Natural • Continuous radiation • Highly penetrating • Propagating along straight lines (on average) • Hidden chambers in pyramids (Alvarez, 1970) • Volcanology (Tanaka, Diaphane collaboration)

  3. 2D Muography and MPGD at Saclay If 50 cm long telescope… Scintillator (~1 cm resolution) Micromegas (0.3 mm resolution) • Revolution for preciseimaging • WatTo exp. already elicited interests from IAEA and French Interior Ministry • Other applications in archeological or mining prospections: cf ASACUSA tumulus cavity in soil mining

  4. Beyond muography: 3D tomography • Direct application for homeland security (Los Alamos, 2003) • Manyprojects in UK, Italy, Canada, China, Russia, France, Israel,…

  5. 3D tomography and MPGD at Saclay Performance with compact (50 cm between detectors) setup 1st goal of DNDO for detection of 4kg of U in 2016… …today First test on a small part with Lead brick, simple POCA • New applications for precise • imaging are nowemerging if • longer exposure… thanks to spatial • resolution of MPGD Detection in 2’ possible

  6. 3D tomographywith longer exposure Wood board! Limestone Pliers Lead brick Iron structure in the limestone (from Historic Monuments) Not neutrons, not X-rays… just free muons! And with compact, transportable setup

  7. Muon metrology Muon metrology, e.g. deformation measurement of buildings But can it work with (necessarily) compact instruments?

  8. Muon metrology • Buildings in cities (old careeers, metro tunnels, vibrations, …) • Old monuments on unstable ground • Hydro dams • Bridge (road, pillars) • Tunnel construction (localization) • Landslide • … Elicitedinterestsfromseveral civil engineering companies

  9. Conclusion Development of muon telescopes at Saclay withunprecedentedresolution → usinggeneticmultiplexing => lowconsumption, cheap, transportable, autonomous → withoutexternal trigger (DREAM auto-trigger function) These instruments have lots of applications, existing or new → muography: 10-50 times betterresolutions thanexistingtelescopes → tomography: very compact instruments, transportable for in situ experiments → metrology: cannowreachpositioning at 20-40 m distance, evenwith obstacles Elicitedmanyinterests in differentfields, fromgovernment to industry There is a lot to do, and we are of course open to collaborations!

  10. Addendum: geneticmultiplexingwith pixels Genetic multiplexing presented in 3rd MPGD conference (Zaragoza) questions whetheritcanbeextended to 2D (pixels) → fullyisotropic, no unfavoured direction → but virtually impossible to make connections withelectronics!

  11. Addendum: geneticmultiplexingwith pixels • A practical solution is to multiplex on the basis of 2 prime numbers p and q l: returning strip pitch (~0.2 mm) px: pixel pitch along one direction

  12. Addendum: geneticmultiplexingwith pixels • Example with 1 and 2 track events (color is time) (NB: as in 1D, the degree of multiplexing can be adjusted to the flux)
