A Multichannel Nanoparticle Scintillation Microdevice with Integrated Waveguides for Alpha, Beta, Gamma, X-Ray, and Neutron Detection
2006
This paper reports on a glass microdevice with a new patterned nanoparticle composite resin that detects and discriminates all species of radiation emitted from fissionable bomb making materials. Tailored charge conversion nanoparticles doped into a fast electron scintillating resin produce different optical pulses specific to the radiation species. The resins are integrated into a glass substrate where deep cavities are made using microsandblasting, forming independent optical paths leading to fiber-optic attachments. A separate, off the shelf Photo-Multiplier (PM) tube measures the light pulse.
