This paper presents a summary and some deeper details about the experiments presented at the 22nd International Conference on Condensed Matter Nuclear Science (ICCF22). It reports on the experimental study of LENR phenomena in Constantan (Cu55 Ni44 Mn1) from its inception in 2011 to the most recent experiments.
Good job with search,
Great with update from Francesco CELANI , Would be nice with a comment
QuoteThis paper presents a summary and some deeper details about the experiments presented at the 22nd International Conference on Condensed Matter Nuclear Science (ICCF22). It reports on the experimental study of LENR phenomena in Constantan (Cu55 Ni44 Mn1) from its inception in 2011 to the most recent experiments. Using an empirical approach we identified the effect of surface modification of the Constantan wires with coatings comprised of elements that enhance the absorption behavior, and oxides with low work function for electron emission. We also explored certain geometrical arrangements of the wires such as knots and coils in order to induce local thermal gradients and predictable hot-spots. Moreover, the DC polarization of the wires by a counter-electrode proved to be a versatile approach to induce non-equilibrium conditions that are essential for Anomalous Heat Effects (AHE), especially when a dielectric barrier discharge (DBD) is produced. From the review of experiments summarized in this article, we obtain indications that the main parameter controlling the AHE is the flux of reactive species through the surface of the loaded material. As a consequence, all other external conditions of the reactor core (voltage-current, temperature, pressure, electric field stimulations, DC and/or AC external fields), can be seen as co-factors that enable a flux of active species through surfaces and in the bulk of the materials. Although most of the tests are in agreement with a possible flux model, some results still lack an interpretation, probably due to limits of the experimental setup.

What happens to the excess heat
without thorium?
Which gamma peaks are most important...the "Thallium" ones at 500 -600..the Ac 228?....
From the report
"
The gamma source contains 10 g of 232Th in form of Thoriated Tungsten (i.e. electrodes used for TIG welding).
Thorium is dispersed at 2% concentration w/w in a matrix of W.
The specific activity of 232Th is 4.07 x10(3 )Bq/g, mostly alpha and beta radiations.
In addition there are several gamma, even at high energies (2614keV), due to his decay products (228Ac, 212 Bi, 212Pb, 212Po, 224Ra, 228Ra, and 208Tl).
The tube were the material is inserted is a 2 mm tick stainless steel tube, hermetically closed.
the measured gamma activity, measured using just a simple Geiger Muller detector, is over 10 times larger of local background

"
Moreover, a 3⇥3 inch NaI(Tl) detector was successfully used to identify the 232Th gamma peaks up to 2 MeV of energy"
Is it possible to use the gamma spec to see what is happening with the constantan-deuterium gamma spectrum..at low kev 20 --300 kev?
The glass shield will absorb some of the gamma.. but certainly not as much as stainless steel in the Mizuno reactor..

Good job with search,
No search required, I use the 'follow' feature of ResearchGate to get automated update triggers by e-mail.
I am not sure Francesco Celani is actively following this forum.
For questions or comments it may be better to respond to the publications at ResearchGate itself.
This paper is part of one of the 4 projects that Celani created there (requires account login).
