Putterman Crystal Fusion Device Duplicated, Improved

Seth Putterman's crystal fusion device has been duplicated by a Rensselaer Polytechnic Institute team that claims to have improved on it.
A research team led by Seth Putterman, professor of physics at UCLA, reported on a similar apparatus in 2005, but two important features distinguish the new device: “Our device uses two crystals instead of one, which doubles the acceleration potential,” says Jeffrey Geuther, a graduate student in nuclear engineering at Rensselaer and lead author of the paper. “And our setup does not require cooling the crystals to cryogenic temperatures — an important step that reduces both the complexity and the cost of the equipment.”


“Nuclear fusion has been explored as a potential source of power, but we are not looking at this as an energy source right now,” Danon says. Rather, the most immediate application may come in the form of a battery-operated, portable neutron generator. Such a device could be used to detect explosives or to scan luggage at airports, and it could also be an important tool for a wide range of laboratory experiments.

The concept could also lead to a portable x-ray generator, according to Danon. “There is already a commercial portable pyroelectric x-ray product available, but it does not produce enough energy to provide the 50,000 electron volts needed for medical imaging,” he says. “Our device is capable of producing about 200,000 electron volts, which could meet these requirements and could also be enough to penetrate several millimeters of steel.”
