Ionoacoustics is an innovative method that employs the acoustic wave emitted by pulsed ion beams slowing down in water. We present the newly developed I-BEAT detector that determines ion bunch properties on a single bunch basis: the I-BEAT detector (Ion-Bunch Energy Acoustic Tracing). Relativistic ions are stopped in a water phantom surrounded by up to four ultrasound transducers for three-dimensional reconstruction of the dose deposited by the ion bunch. As the detector is radiation hard and electromagnetic pulse resistant, it is especially suited to fill the lack of reliable online detection methods for laser-accelerated ions. Additionally, we recently demonstrated that ionoacoustic beam monitoring is also possible in transmission mode. We discuss our results obtained with laser- and conventionally accelerated ion bunches being especially interesting for ion bunch position and intensity monitoring.
