SMILE soft X-ray Imager flight model CCD370 pre-flight device characterisation
Autor: S. Parsons, D. J. Hall, O. Hetherington, T. W. Buggey, T. Arnold, M. W. J. Hubbard, A. Holland
Publikováno v: Earth and Planetary Physics, Vol 8, Iss 1, Pp 25-38 (2024)
Throughout the SMILE mission the satellite will be bombarded by radiation which gradually damages the focal plane devices and degrades their performance. In order to understand the changes of the CCD370s within the soft X-ray Imager, an initial chara

Exploration of Fourier based algorithms and detector designs for pulse shape discrimination
Autor: M.P. Taggart, Paul J. Sellin, Michael W. J. Hubbard
Publikováno v: Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment. 930:64-73
We investigate the performance of Fourier-based neutron/gamma Pulse Shape Discrimination (PSD) algorithms applied to plastic scintillators that are coupled to silicon photomultipliers (SiPM). The detector acquired data from a mixed fast neutron and g

Assessing the suitability of three proxy sources for the development of detectors of special nuclear materials
Autor: M.P. Taggart, Chris Allwork, Paul J. Sellin, Michael W. J. Hubbard, Michael Collett
Publikováno v: Journal of Radiological Protection
Numerous techniques and equipment have been developed to provide a capability for the detection of special nuclear materials (SNM), but due to the necessary security measures surrounding these materials alternate, or proxy, neutron sources are often

Suitability of a SiPM Photodetector for Implementation in an Automated Thermoluminescent Dosimeter Reader
Autor: M.P. Taggart, S.M. Jafari, Annika Lohstroh, A. Charoupa, Michael W. J. Hubbard, M. Stroud
It is widely known that SiPM photodetectors have a strong temperature dependence. TrueInvivo is currently developing an automated TLD reader with the intention of replacing the PMT with a SiPM, taking advantage of the low power consumption, small for

Experimental verification of consistency of micro-silica glass bead thermoluminescent detectors for mixed gamma/neutron irradiation
Autor: K. Ley, Annika Lohstroh, C. Termsuk, M.P. Taggart, P. Hima Bindu, Michael W. J. Hubbard
Publikováno v: Radiation Physics and Chemistry. 179:109210
The thermoluminescent response of micro-silica glass beads has prompted their use as dosimeters across a variety of incident ionising radiations. This work presents the latest of a campaign to investigate, and confirm, the suitability of glass beads
