WebA historical self-portrait painted by Sir Arthur Streeton (1867-1943) has been studied with fast-scanning X-ray fluorescence microscopy using synchrotron radiation. One of the technique's unique strengths is the ability to reveal metal distributions in the pigments of underlying brushstrokes, thus providing information critical to the interpretation of a painting. WebDead-time and pile-up are two major problems for conventional detectors especially where there are high count-rates induced by an intense X-ray beam. Maia partly gets around these problems by having 384 detectors working simultaneously to collect many more X-rays than a single detector.
