Our Geant4 simulation work into the effects of radiation of ultrasonic transducers, was presented at the ENSAR2 Workshop on Geant4 in Nuclear Physics, held at Ciemat, Madrid. The full poster can be found at: https://indico.cern.ch/event/746466/contributions/3345606/
Last week the Innovate UK ReDRESS team has successfully irradiated three different ultrasound transducer technologies with gammas and neutrons at the Jozef Stefan Institute TRIGA nuclear research reactor. The goal is to demonstrate the levels of radiation resilience for non destructive testing in the nuclear industry. Detailed simulations are also being performed by the University of Sheffield to establish the neutron and gamma fluences inside the devices under test, as well as quantities such as total ionising dose, neutron kerma, and DPA. The results will be published.
A UK consortium of tech companies with the University of Sheffield as the academic partner, successfully irradiated three different ultrasound transducer technologies with gamma at the Dalton Cumbrian Facility, University of Manchester, UK in December. The goal is to demonstrate the radiation resilience of ultrasound transducers up to ionising dose rates of 10 MGy. Detailed simulations have been performed by the Sheffield Radiation Effects team to establish the gamma fluence and dose profiles inside the devices under test. The results will either be presented at a conference, or be published in a peer reviewed journal.
