DESCRIPTION:Radiation detectors enable many aspects of our modern lives\, 
 from the light sensors in our smartphone cameras to PET scanners that info
 rm treatment of cancer. Particle physicists have often led the development
  and exploitation of cutting edge radiation detectors to identify particle
 s while measuring their energies\, positions and directions.\n\nMany radia
 tion detectors use scintillators\, which traditionally have nearly always 
 been transparent to allow detection of the light. Our new counter-intuitiv
 e approach called “LiquidO” is to use highly scattering opaque scintil
 lator. The opacity causes the light to bounce around close to where it is 
 produced and then optical fibres extract the light. By looking at which fi
 bres are hit and how much light each one sees\, precise particle position 
 and directional information can be obtained. We’ve demonstrated that our
  approach outperforms existing scintillator technology by a factor of two.
  With further R&D the resolution is expected to improve by 5-10x\, for a s
 imilar cost to existing technology. Or\, importantly for some applications
 \, reduce the detector cost by 5-10x while maintaining the resolution. \n\
 nThere are multiple applications for high-resolution and cost-effective ra
 diation imaging\, from Compton cameras for gamma ray imaging to precision 
 muon tomography. In particle physics\, the CLOUD neutrino experiment will 
 pioneer new physics measurements using the novel LiquidO opaque scintillat
 or technology.
