138. Development of Polycrystalline Solid-State Radiation Detectors

Justin Reiss (Penn State University)

05/03/2025, 12:00

Invited Talk

Solid-state gamma-ray detection devices have traditionally relied on single crystal materials due to their reduced crystallographic and bulk defect density, and resultant charge transport properties. Development of new, room-temperature capable semiconductors has been ongoing for decades, and continuously experiences challenges in costly fabrication and scaling towards larger area devices. In...

119. A Neutron Sensitive Detector using 3D-Printed Materials

Adam Barr (University of Manchester)

05/03/2025, 12:30

Oral Presentation

In this presentation, we will outline the development of a neutron-sensitive scintillator produced through 3D printing and its integration into a detector using a high-speed optical camera. The scintillator was produced using the Fused-Deposition Modelling (FDM) method of 3D-printing, whereby a thin plastic filament is heated and extruded to create layers of an object. Two methods for creating...

104. Low Power, Compact, Dual Mode Detectors for Nuclear Security Applications

Bjoern Seitz

05/03/2025, 12:45

Oral Presentation

The detection of special nuclear material remains a matter of utmost importance due to potential security issues. Current neutron detection relies upon a combination of a 3He detector and a plastic scintillator. 3He is a rare material with decreasing global supply, so an alternative solution needs to be developed. This solution should be both low power and robust, in order to be deployed in...

114. Evaluating the suitability of organic semiconductor detectors for nuclear security

Aled Horner (Queen Mary, University of London)

05/03/2025, 13:00

Oral Presentation

Organic technologies are of active scientific interest due to their tuneable, scalable, and cost-effective nature. I will present radiation sensors based on organic semiconductor technology, particularly applications related to detection of hadronic radiation consisting of α radiation and thermal and fast neutrons. Neutron detection is useful in various fields, from fundamental particle and...
