From: I-BEAT: Ultrasonic method for online measurement of the energy distribution of a single ion bunch
Experimental scheme of I-BEAT. (a) The short ion bunch enters the water volume via an 11 µm thick titanium foil (1 cm diameter), depositing its energy in the water and generating an acoustic wave, which is measured via a transducer. This generates a signal as shown in (b), where the orange curve is an example trace for a mono-energetic 9.4 MeV proton bunch measured at the MLL Tandem accelerator and the blue curve represents simulated results, considering an ideal detector with equal conditions.
