Abstract
- A -introscopy method and an installation using "electronic focusing" of -quanta transmitted through the studied object are proposed. The apparatus contains a powerful 60Co-source; a device for positioning the studied object; and a measuring facility, including a thin scintillation coordinate detector-scatterer with 64 silicon photomultipliers (SiPMs) and digital detector pulse processors (PDPs), a total absorption scintillation detector with analog-digital PDP, a unit for coincidence and energy event selection and on-line coordinate calculation, and a communication interface to a PC. The spatial resolution achieved for thick objects is 400 μm. The theoretical limit is μm. [ABSTRACT FROM AUTHOR]
