Observation of nuclear fusion driven by a pyroelectric crystal
B. Naranjo, J.K. Gimzewski and S. Putterman
Nature 434, 1115-1117 (28 April 2005)
doi: 10.1038/nature03575
Supplementary Methods
Neutron detection methods including energy scale calibration, pulse shape discrimination, and Monte Carlo efficiency calculation.
Supplementary Video S1
This movie is a real-time presentation of the crystal fusion raw data shown in Figure 2 including raw PMT traces of valid neutron hits.
Supplementary Video S2
This movie shows the phosphor screen image (25.4 mm diameter) of an ion beam produced upon heating a pyroelectric crystal. Deuterium gas pressure was set to 0.2 Pa. The phosphor intensity, as measured by a CCD camera, is proportional to beam current density. In the central frame, the phosphor intensity is displayed topographically.
Supplementary Figure S1
This figure shows the phosphor screen image (25.4 mm diameter) of an ion beam produced upon heating a pyroelectric crystal. The four frames were taken from Supplementary Movie 2. They were separately normalized and gamma corrected to enhance detail. Note the copper mesh's shadow and the FIM image of the tungsten tip.
