Pion Detection Using Single Photon Avalanche Diodes
Autor: Anthony Frederick Bulling, Ian Underwood
Publikováno v: Sensors, Vol 23, Iss 21, p 8759 (2023)
We present the first reported use of a CMOS-compatible single photon avalanche diode (SPAD) array for the detection of high-energy charged particles, specifically pions, using the Super Proton Synchrotron at CERN, the European Organization for Nuclea

Post-Operative Monitoring of Intestinal Tissue Oxygenation Using an Implantable Microfabricated Oxygen Sensor
Autor: Jamie R. K. Marland, Mark E. Gray, David J. Argyle, Ian Underwood, Alan F. Murray, Mark A. Potter
Publikováno v: Micromachines, Vol 12, Iss 7, p 810 (2021)
Anastomotic leakage (AL) is a common and dangerous post-operative complication following intestinal resection, causing substantial morbidity and mortality. Ischaemia in the tissue surrounding the anastomosis is a major risk-factor for AL development.
