چکیده انگلیسی
It is not easy to design a calibrator system able to reproduce the time and directivity patterns of the acoustic pulse produced in an ultra high energy neutrino interaction. Linear arrays of acoustic transducers with coherent emission have been proposed, but it might result in a long array with many elements, increasing the cost and making the deployment and operation much more complex. In this paper, we evaluate the possibility of using an alternative approach using parametric acoustic sources to generate neutrino-like signals. This non-linear acoustic effect can also be applied to transient signals allowing to generate them by a “special modulation” at a larger frequency. The technique has the advantage of being much more directive since the directivity of the parametric source is similar to that of the large frequency used, and therefore it will result in a much more compact design with fewer sources. Here, we present the studies performed with planar transducers in a tank to evaluate the possibilities of the technique, which seems very promising according to our results.
