Characterization of LR-115 as an SSNTD[edit]

For the experimental work described in the next section, LR-115 has been chosen as a Solid State Nuclear Track Detector, because of the relative ease of development and interpretation of the tracks formed by charged particles in this material. Some work needs to be done to estimate the range of energies detected; LR-115 is insensitive to charged particle radiation below a certain energy, and, as well, becomes less sensitive to such radiation at higher energies. If anyone has access to calibrated sources of proton radiation, which is the radiation expected (for the most part) in the experiment, exposure of the material to known radiation sources and development for various etching times would help with later interpretation of results. Contact Abd for information about obtaining LR-115 and using it. (This information will also be provided on Cold fusion/Lab/LR-115).

Calibration with neutrons would also be useful, of course. Neutrons are primarily detected with this material through collisions with protons in a proton-rich material, which, in the experimental work undertaken below, would be the acrylic wall of the experimental cell, or, in some cases, the polyester base of the LR-115. While it is possible that we will see some "triple tracks," which are alpha particle tracks (three of them originating in a common point) produced by a neutron collision with a carbon nucleus in some material (the CR-39 polycarbonate in the SPAWAR work), these should be relatively rare.

Attempt to replicate SPAWAR neutron findings[edit]

One or more of us will run a co-deposition cell for a few weeks, approximately following the Galileo protocol, but using a gold cathode (reported to produce neutrons at much higher levels than the silver of Galileo), a reduced cathode length and thus reduced palladium chloride (for the same plating thickness), and lower currents (for the same current density), and thus reduced heavy water consumption, while looking for evidence of neutron radiation in addition to other possible adjunct phenomena. This will be a standard cell, fully documented, designed to be inexpensively produced for wide replication. Estimated cell cost: $100, including solid state nuclear track detectors (LR-115). Required equipment: power supply plus current regulators to maintain protocol currents.

A control cell, identical except for the use of light water in place of heavy water, will be run in series. Estimated cell cost: $70.

Participants here may contact Abd, here or by email through the Wikiversity system, for information about the protocol and obtaining materials, or may independently obtain these. Results (positive or negative) will be reported here, as well as being submitted for publication.

Letts dual-laser stimulation/[edit]

Dennis Letts has done some remarkable experiments that appear to be reproducible. His protocol and results will be described here.
