Window in Wixhausen's baroque church
This window in Wixhausen's baroque church, close to GSI, was commissioned from artist Thomas Duttenhoefer in 1997. It illustrates in its top right pane the deposition of energy with distance for photons (the smooth curve) and for carbon ions which deposit their energy at the end of their path. The pane below shows the corresponding survival rate for cells along the path of the ions. The curves in the window are not to scale and are based on graphs where the superior biological effectiveness of carbon ions is clear from the cell survival graph.
