Ion Bunch Energy Acoustic Tracing (I-BEAT)
We develop instrumentation for laser-driven ion bunches in close collaboration with experts in the chair for medical physics. Since several years we investigate the acoustic wave that are excited when a very short ion bunch deposits energy in water, that is we record the acoustic trace exited by indivual ion bunches. The signal shape enables the reconstruction of key parameters such as ion energy and energy spread, the most important traces of the ion acceleration process. Consequently we dubbed this method Ion-Bunch Energy Acoustic Tracing, or I-BEAT in short.
