Originally designed for charged particle detection and later modified for fast neutron detection, the MicroMegas detector concept has proven capable of processing a high charged particle rate with relatively fast recovery times to minimize dead time. The company's possible breakthrough, the Pulsed Fast Neutron Analysis machine, shoots neutrons into containers to determine which chemical substances are present, in addition to tracing objects' shapes the way X-rays do. Because fast neutrons, the type emitted by nuclear reactions, are particularly difficult to trap and measure, dosimeters first use a "moderator"--something containing hydrogen--to interact with them and "slow" them down. |
