Development and implementation of novel radiation sensors for biological applications
Objectives: Optimize CZT and SrI2(Eu) sensor fabrication to enable low power and light weight sensor applications; expand current capability to process CZT and SrI2(Eu) scintillators into detector pixel arrays; fabricate, test and evaluate handheld probes and evaluate them for use in dual energy X-ray absorptivity and radio-identification methods.
Team Coordinator: Arnold Burger, PhD (Subproject PI and Center PI)
Collaborators: Qingxia Li, PhD (Fisk, mathematics); Lei Qian (Fisk, CS), Vanderbilt Collaborators: Todd Peterson and Michael Stabin.
Scientific Impact: Develop innovative nuclear radiation sensing technologies pioneered at Fisk and based on novel materials and innovative instrumentation to achieve more sensitive and lower cost bone mineral density measurements.
Innovation: Breakthrough in technologies based on discovery of a new class of scintillators, SrI2(Eu2+), that together with CZT may provide higher-performance nuclear radiation sensing that have the potential to supplant former scintillation-based technology.
