Novel Position Sensitive Photosensor Technology for Rare Decay and Rare Particle Detection

To this day, large-area photon detection relies on an expensive, Pre-WW2 vacuum-tube technology, while its only modern alternative thus far, the millimeter-sized semiconductor devices, remain unsuitable for most large-area applications. Our novel photosensor technology has the capability of supplanting the old technology with a modern, cost-effective, and uniquely robust alternative, which provides sensitivity to visible and ultraviolet light, offers exceptionally low intrinsic radioactivity, low noise, and position sensitivity. Our novel photosensor technology has the potential to revolutionize photon detection in application areas including large experiments in fundamental science, functional medical imaging, and nuclear security. The goal of the presently proposed project is to develop the first position-sensitive photosensor that will provide an ultimate level of radio-purity at an affordable cost. The approach will include designing the photosensor based on two inventions, building a functioning prototype, testing, and evaluation of the protype. Using our fully equipped domestic R&D facility, we intend to prove our novel proposed photosensor concept in Phase I by creating a fully functional prototype. Initial tasks will involve numerical simulations and finetuning of the electron optics. Next, we will make CAD designs of the prototype components and associated hardware. In the following step, we will manufacture components, and prepare them for the final assembly. The assembly of the protype will be conducted in our ultra-high vacuum manufacturing system, to be followed by detailed testing and evaluation of the prototype. The beneficiaries of our technology go well beyond the early adopters in the Fundamental Science Research market, which prompted us to develop this novel technology. The broad radiation detection market needs an improved and more affordable solution. Our technology is well positioned to address a wide spectrum of important societal needs, particularly by opening new markets that were previously considered virtually unachievable due to the shortcomings and/or high cost of current technologies. For instance, thin and lightweight panels hosting our novel photosensors can serve as modules for ultrasensitive whole-body- enclosing medical scanners that could provide ultra-low-dose cancer screening for a wider, even symptom-free population as a preventative measure. The same invention enables custom-shaped detectors of illicit radioactive materials. Ultimately, this project can lead to the creation of a highly profitable and multi-faceted hi-tech industry.
