Heavy Ion Microprobe The Heavy Ion Microprobe at GSI can focus an ion beam from the UNILAC linear accelerator to a spot smaller than one micrometer in diameter. To achieve this, a 10µm section of the incoming [...] location of this ion optical image of the micro object aperture is defined by a beam-scanning magnetic dipole field. A low-noise electron detector with high gain will detect impacting ions by amplifying the [...] the electron cloud emitted from the sample for each incoming ion. A fast electrostatic beam switch will then block further incoming ions. Spatially resolved radiation hardness testing in microelectronics
