The HEARTS@GSI facility / Cave A showcasing a sample setup for electronics irradiation (left) and the current electronics target station (right). In the left picture the beam traverses from the left to right, exiting the vacuum exit window, through the beam monitors until it hits the devices under test. In the right picture the beam points towards the viewer. (Image: GSI)
