This unique performance is realized by the use of a chromatic imaging system, which consists of four quadrupole lenses [1]. Chromatic imaging systems have a mono-energetic focal length. That means, if a target with areas of different energy losses is to be investigated, it is only possible to focus on one proton energy leaving other areas of interest blurred. A simple method of focusing multiple energies at once and thus increasing the depth-of-field is the use of multiple detector stations along the beam axis. Proton images captured at downstream detector positions can be combined into a single image using a method called ’focus stacking’. A complete cancellation of the position- and energy dependent 2nd order chromatic aberrations that mostly affect the current image quality of pRad [2] is only possible by using an achromatic imaging system. Following the proposals in early design studies at LANSCE [3] a new prototype achromatic system is currently being developed for a 25 MeV S-band electron accelerator.}}, }
