Our Ion Beam Facility (IBF) makes it possible to do materials research with a highly energetic ion beam.
In the heart of the machine, light weight ions, like hydrogen, helium, nitrogen and neon are created and accelerated with a maximum of 3.5 million volt. The beam of ions formed this way, is filtered, steered and focused by magnets, until it reaches the destination of choice with well defined properties. One possible destination is the Target Exchange and Analysis Chamber of Magnum-PSI.
When the light weight ions hit a target, a small fraction bounces back with an energy/speed that depends on the mass of the target material. By measuring the energy of the so-called back scattered ions, it is therefore possible to deduce the composition of the target material. Another detection method measures the atoms of low mass that can be knocked out of the target. A third option is to measure the reaction product of a nuclear reaction. In Magnum-PSI, this allows us to measure how much deuterium has been captured by the target during plasma exposure. This information is important to tackle the fuel retention problem in DT-fusion devices.
