Investigation of the interaction of the ion beams with deuterated crystal structures at the HELIS facility

Abstract

The paper reviews results obtained in the course of low energy nuclear reactions experimental study using the HELIS facility (LPI).

The analysis of DD-reaction yields in deuterated crystalline structures at deuteron energies of 10–25 keV

has shown a significant amplification effect.

It was found that the exposure of deuterated targets both to 10–25 keV H+ and Ne+ ion beams and 20–30 keV X-ray radiation beams

results in stimulation of DD-reaction yield.

For CVD diamond and PdDx targets, it was shown that the magnitude of the neutron yield

is affected by the orientation of the sample with respect to the deuteron beam.

The possible explanation of the said effect may be attributed to

the channeling of deuterium ions and neutron (DD reaction products) in textured targets.

It was found that the heat release is much higher when D+ ion beams act upon the TiDx target than in case with H+ and Ne+ beams.

The heat release depends upon the deuterium concentration in the target and the deuteron beam current density.

"Additional peaks" were observed in the X-ray fluorescence spectra, but those are not related to any element

and are seemingly associated with diffraction processes in deuterated palladium and CVD diamond.

"

The neutron yield in the energy range of 10 - 26 keV per beam-current unit does not
exceed 10-10 which can not explain the observed excess of heat emission from the
Ti/TiO2:Dx target by «classical» channels of DD-reactions (1) and (2). "

NOTE: although the authors say that 25 keV is low energy... this is only relative to Mevs... not eVs..

Peer review by dinosaur peers excludes exotic genes,,

A heat production of 1W from an ion beam is a puzzle.

The conversion of 24 MEV to only heat is a puzzle..

In the reaction (4), the main process responsible for the energy radiation of the
compound nucleus 4He* to the ground state 4 He

is the exchange of virtual photons
between the compound nucleus and the nearest electrons, including electrons of the
crystal lattice.

At the same time, the decays with nucleon emission are energetically forbidden.
In the reaction (4),

d+d → ⁴He + Q (24 MeV).

the energy of about 24 MeV is released, which is utilized for
heating up the whole crystal structure of the target. For attaining of power of 1 W,
2.6x10(11 )such reactions would be necessary. During our experiment, (approximately
104 s) the amount of about 1015 of helium atoms is formed, which is insufficient for
mass-spectrometry diagnostics. The heat-emission excess is the only indication of the
reaction (4), registered in our experiment.

Negodaeva sent me the relevant paper..

The CVD and Pd deuteride emitted low low keV peaks... there seems to be some pattern

dare I say quantisation..

but it was not seen with zirconium or titanium

Abstract—The emission of X-ray quanta, neutrons, and charged particles from deuterated structures under X-ray irradiation is studied. Targets (deuterated chemical-vapor-deposited (CVD)-diamond, palladium, zirconium, and titanium)

are irradiated with the use of an X-ray tube equipped with a polycapillary lens with an
energy of < 30 keV and an X-ray tube equipped with a collimator with an energy of up to 25 keV.

Differenttypes of detectors, such as a multichannel neutron detector based on He-3 counters, a CR-39 plastic trackdetector, and silicon surface barrier detectors, are used.

The emission of neutrons with an energy of above10 MeV and alpha particles with an energy range of 7–15 MeV is revealed.

This result indicates the possibility of stimulating multiparticle fusion reactions between deuterium nuclei in solid deuterated structures.

The analysis of X-ray fluorescence spectra demonstrate the existence of “additional” peaks, which cannot be identified by any characteristic X-ray fluorescence line.

Their appearance cannot be associated with any known element or diffraction process.

The nature of the origination of the “additional” peaks requires special study
