A new Monolithic Active Pixel Sensor, originally developed to upgrade the ALICE inner tracking system during the second long shutdown of LHC, is on its way to Bergen University for a very different application – Proton Computed Tomography (Proton CT). The University will use the technology for research and development of a Proton CT proof-of-concept project using the high time and space resolution of the ALPIDE chip. Proton CT is a technique based on the measurement of a proton’s position/trajectory and energy before and after traversing an object to reconstruct an image of the object. Unlike conventional X-ray CT systems, where the technology is widely understood, proton CT still faces some technological challenges
