      RIID Recapitalization

      June 20th, 2019

      The US Department of Homeland Security has posted a Request for Information on RIID Next Generation: Radiation Detection Equipment and Operations
      Solicitation Number: 70RDND19I00000004
       
      Are you considering responding to the Basic Handheld Program - RIID Recapitalization (Radseeker DLs)?
       

      Saint-Gobain offers two solutions that will help you meet all requirements! 

      • CLLB for dual detection
      • Enhanced LaBr for best resolution
      What’s more? These are commercially available off-the-shelf! (COTS)
       
      CLLB 
      CLLB (95% enriched 6Li) is a gamma-neutron scintillation detector that is well suited for many different classes of hand-held instruments.  Using Pulse Shape Discrimination electronics for Neutron Detection, customers can eliminate the need for an additional set of electronics and 3He detector.  With dual gamma/neutron detection and an energy resolution of 4%, CLLB offers a dramatic change in what is possible in a hand-held instrument.
       
      Saint-Gobain Crystals has been manufacturing CLLB detectors since 2017. Multiple customers have sampled this product, and there are several detectors currently in field-use.
       
      Enhanced LaBr
      With an FWHM measured at 2.2% at 662keV, Enhanced Lanthanum Bromide is the ultimate scintillator of energy resolution.
       
      In addition, the 227AC peak of enhanced LaBr enables you to build a self-calibrating instrument, eliminating the need for external sources. The227AC peak, meanwhile, can be easily eliminated with pulse shape discrimination.
       
      Saint-Gobain Crystals has been manufacturing Enhanced Lanthanum Bromide detectors since the fall of 2016. Multiple customers have sampled this product, and there are several detectors currently in field-use, both in the US & abroad.
      Over its history, Saint-Gobain has deployed hundreds detectors in SPRDs, RIIDs, Backpacks, Mobile Systems and Portal Monitors across the world.
