Direction-position sensing fast neutron detector

A neutron detection system for determining the direction of the source of incident neutron radiation comprising a microprocessor and a detecting chamber system containing at least two axis of symmetry containing a fluid configured with a plurality of detecting transducers for detecting bubbles within the chamber system and acoustic transducers for establishing acoustically tensioned metastable state within the liquid in the chamber system that is radially symmetric along the at least two axis of symmetry;

• the detecting transducers being configured with the chamber system to receive signals obtained from bubbles in the chamber system and transmit them to a microprocessor, the signals being sufficient to allow the microprocessor configured with an algorithm for determining the three dimensional position of the bubbles in the chamber system to determine the position of bubbles within the chamber;
• the acoustic transducers being configured with the chamber system to introduce a sound wave into the liquid in the chamber system sufficient to introduce an acoustic metastable state in the liquid sufficient to nucleate bubbles upon exposure to incident neutron radiation, the acoustic metastable state being introduced in response to a signal from a microprocessor;
• and a microprocessor for identifying in 4π the direction of the source of incident neutron radiation from bubble signals generated within the chamber system.
