Large Area, Low Cost, High Sensitivity LAPPD Sensors for Nuclear Science and Medical Imaging
Presented by Dr. Michael J. Minot Date: Nov 2, 2020 2020 Virtual IEEE Nuclear Science Symposium and Medical Imaging Conference https://nssmic.ieee.org/2020/ Content: LAPPD is an MCP based large area picosecond photodetector with single-photon sensitivity at high spatial resolution, with an active area of 380 square centimeters in an all-glass or ceramic hermetic package. LAPPDs are now being produced on a routine pilot production basis, and are being made available to early adopters for high energy, nuclear science and medical imaging applications. An update on the latest performance results achieved with LAPPD will be provided. Design features of both GEN I and GEN II LAPPD are reviewed as well as the latest picosecond timing results measured at Incom and in collaborating laboratories. Development of dedicated LAPPD read-out electronics is discussed, together with life testing studies that are now underway. Efforts to qualify LAPPD for nuclear science and medical imaging applications are discussed, including PET qualification trials that are underway at UC Davis. We conclude with a discussion of the cost advantages inherent to the design and process technology used for LAPPD recognizing that full acceptance of any emerging technology including LAPPD, will involve finding the appropriate balance between technical capabilities and costs.
