Photo of the latest measurement in Hamburg. Scattering from the gold foil is done inside a vacuum chamber to minimize background radiation. The vacuum chamber has several windows to measure the scattered radiation. In addition to the measurement using a Compton polarimeter (left), a germanium semiconductor detector (right) was used to measure high-resolution energy spectra.
