The Deuterium lamp can be instructive in explaining why Rossi likes the E-Cat X reactor so much, why Holmlid’s reaction is superior to the Rossi low temperature Ni/H reaction, and why arc discharge is the best stimulator of the LENR reaction. This line of thinking also might open up the possibility that might lead to a optical based chain reaction.
As a definition of terms, Extreme ultraviolet radiation (EUV or XUV) or high-energy ultraviolet radiation is electromagnetic radiation in the part of the electromagnetic spectrum spanning wavelengths from 124 nm down to 10 nm, and therefore (by the Planck–Einstein equation) having photons with energies from 10 eV up to 124 eV (corresponding to 124 nm to 10 nm respectively). EUV is naturally generated by the solar corona and artificially by plasma and synchrotron light sources.
Its main uses are photoelectron spectroscopy, solar imaging, and lithography.
To set the stage, we know from Holmlid that UV based LENR reactions produce an abundance of subatomic particles including K-mesons, pions, and electrons. We know from Dr Kim’s experiments at DGT, that solitons explode in a Bosenova releasing XVU and X-ray radiation, and from R. Mills we know that 10 nn radiation is produced in his reaction (I say it is LENR based)

“Polariton engineering imperatives”
A deuterium arc lamp (or simply deuterium lamp) is a low-pressure gas-discharge light source often used in spectroscopy when a continuous spectrum in the ultraviolet region is needed.
Plasma “arc” or discharge lamps using hydrogen are notable for their high output in the ultraviolet, with comparatively little output in the visible and infrared. This is similar to the situation in a hydrogen flame. Arc lamps made with ordinary light-hydrogen (hydrogen-1) provide a very similar XUV spectrum to deuterium, and have been used in XUV spectroscopes. However, lamps using deuterium have a longer life span and an emissivity (intensity) at the far end of their XUV range which is three to five times that of an ordinary hydrogen arc bulb, at the same temperature. Deuterium arc lamps, therefore are considered a superior light source to light-hydrogen arc lamps, for the shortwave UV range.
The UV absorption profile is very low for deuterium. This provides us with a win-win situation with the generation of abundant XUV production using arc discharge and high efficiency polariton production in the XUV range.
The chip production industry has found that plasma based spark discharge produces XUV light. Light produced through techniques now being considered by the chip industry generate a spark that lasts just 20 to 50 nanoseconds can produce very short wavelength light.
Rossi has hinted that his E-Cat X can produce electricity directly from the LENR reaction. The AIRBUS patent also called fro direct electrical production.
As with the Papp reaction in the Papp engine which did not produce any heat, the electrons produced by particle production can be harvested and used to produce the low powered spark even though the very high voltage spark has a high instantaneous power profile because it has a very short duration of discharge.
The XUV can also be fed into the polariton reaction through the Bosenova broadcast of XUV radiation.
If we are utilizing the Holmlid technology using noble metals and deuterium gas we should move away from the production of heat and produce electricity directly from LENR.
