One of the greatest threats to troops in the field today are improvised explosive devices (IEDs).

Most methods currently used to protect against these devices rely on mechanical or directed energy detonation. The US armed forces have expressed a strong interest in technologies with the capability to detect these devices ahead of a moving convoy and alert troops of their location. A functional solution must be portable, reliable, and extremely sensitive at a large standoff distance.

Portable, Powerful, and Reliable IED Detection Systems

The Phoenix mobile neutron generator can be placed on an autonomous vehicle platform at the head of the convoy. The neutron generator will emit a directed neutron beam ahead of the vehicle. When the neutron beam interacts with a hidden IED, the explosive materials in the IED emit characteristic radiation signatures that are detected either by the lead vehicle or by a remote sensor.

Neutron-based explosive detection technologies have been fielded in the past, however, due to relatively weak neutron source strength, detection standoff distance has been limited to less than one meter. The Phoenix neutron source generates more than 1,000 times more neutrons than other off-the-shelf nuclear technologies, it is capable of detecting explosives rapidly from much greater standoff distances (greater than 20 m). This explosives detection system has the potential to save thousands of lives of both warfighters and civilians every year.


Phoenix has partnered with the US Army to develop a compact, high yield neutron source for the detection of improvised explosive devices (IEDs).
