Development of a high-precision flush-mounted sensor with shortened detection time
| German title: | Entwicklung eines hochpräzisen Unterputzsensors mit verkürzter Detektionszeit | |
| Acronym: | ALPHIN | |
| Duration: | 1st June 2020 - 31st May 2022 | |
| Description: | Since there is currently no radon sensor on the market that can be easily integrated into the electrical installation (flush-mounted box) and thus into the building control system of existing buildings and new buildings, this project aims to develop a miniature radon sensor that can make meaningful measurements of both radon gas and its decay products by detecting alpha particles. It is planned to miniaturize the sensor geometry so that it can be installed in a flush-mounted box. The miniature radon sensor is to be constructed in the form of a "Lucacell". It consists of a scintillator and a silicon photomultiplier (SiPM). Alpha particles present in the room air strike the scintillator, which re-emits the excitation energy in the form of light. The SiPM is a sensitive detector for detecting small amounts of light, down to single photons. It operates at low voltages (<60V) and is insensitive to electromagnetic fields. | |
