     28Please find attached a [raw-attachment:Ionoacoustics-project-notes.pdf short document] containing what I said I’d share after the meeting. Briefly, these are:
     29* Summaries of 2 studies in literature. I used ones I’d looked at previously and noted values from. These might not be the most representative. I’ll note my choice of high energy study leaves something to be desired because their signal mostly came from the cylindrical incident beam (and not obvious what came from the BP). Still, hopefully useful for discussion.
     30* A note on stress confinement.
     31* A note on acoustic frequencies.
     32 
     33I omitted my graph of minimum detectable pressures of detectors because in the end this did not feel all that relevant. This was because this graph was limited to higher frequency detectors whereas we are likely going to be most interested in low frequency detectors.
     34 
     35I think the examples give some evidence that clinical energies, as well as more relevant, should provide detectable (low frequency) signals. However, detectability is more readily guaranteed at lower energies. Perhaps the more useful message is clarifying the links between proton energy, BP dimensions, pulse lengths, and frequency content.
