Abstract. Transport processes in geomaterials can be observed with input-output experiments, which yield no direct information on the impact of heterogeneities, or they can be assessed by model simulations based on structural imaging using µ-CT. Positron emission tomography (PET) provides an alternative experimental observation method which directly and quantitatively yields the spatio-temporal distribution of tracer concentration. Process observation with PET benefits from its extremely high sensitivity together with a resolution that is acceptable in relation to standard drill core sizes. We strongly recommend applying high-resolution PET scanners in order to achieve a resolution on the order of 1 mm.We discuss the particularities of PET applications in geoscientific experiments (GeoPET), which essentially are due to high material density. Although PET is rather insensitive to matrix effects, mass attenuation and Compton scattering have to be corrected thoroughly in order to derive quantitative values.Examples of process monitoring of advection and diffusion processes with GeoPET illustrate the procedure and the experimental conditions, as well as the benefits and limits of the method.

“…The granule strength is determined by single granule compression and cr ushing between two platens known as the side crushing test. The macroscopic flow field of the granulators as a function of scale is also investigated using the Positron Emission Particle Tracking (PEPT) facility of the University of Birmingham [26][27][28] and high-speed video recording and image analysis to measure particle motion at the single particle level. In order to provide a mean to interpret the experimental observations, modelling work across the length scale is carried out at macroscopic and microscopic levels.…”
