Partial Replication of Storms/Scanlan Glow Discharge Radiation Experiment
The Storms/Scanlan paper  presented at the 8th international workshop on Anomalies in Hydrogen/Deuterium Loaded Metals in Catania, Italy described two types of radiation produced in a deuterium glow discharge. One type was thought to be mono energetic electrons in the 0.8 MeV range. A second type of emission, obtained when oxygen was added to the D2, was also described by Storms/Scanlan.
We have produced radiation with similar characteristics to this second type of emission. This radiation has been characterized with GM tubes, absorbers, silicon diode detector, and magnetic deflection. We propose that conventional low energy x-rays would produce behavior consistent with our observations.
In oxygen containing plasmas, counts from the 2 mg/cm2 GM tube are seen whenever the glow voltage is greater than about 600V. In D2, H2, He, and N2 plasmas counts start when the glow voltage is greater than 900-1000V. Count rates increase non-linearly with increasing voltage. See Figure 9.
GM Counts are stopped by a 100mg/cm2 plastic absorber; Counts are not seen with a 10 mg/cm2 GM tube.
Count rates for D2+O2 plasmas (V<900) are reduced by 66% with a 1 micron Mylar absorber (0.14 mg/cm2), by 75% with a 1.2 micron Al absorber (0.3 mg/cm2) and by 95% with a 1.8 micron Al absorber (0.5 mg/cm2). Counts are stopped by total areal density of 2.5 to 3.0 mg/cm2.
Similar count rate and absorber attenuation results are seen with D2 +O2 using either Cu or Pd cathodes. Also, similar count rate and absorber attenuation results are seen with H2+O2 and D2+O2 discharges using a Cu cathode.
The CR-39 detected no radiation above background.
No counts above background have been observed with the Si detector.
Transmission through a 1.8 micron Al or 1 micron Mylar absorber increases with increasing glow voltage for voltages greater than 900V. In an oxygen containing plasma, transmission through a 1.8 micron Al absorber or a 1 micron Mylar absorber is constant for voltages less than 900V. See Figures 10 and 11.
Counts are observed during the on periods of the glow pulse, but do not occur (above background) during the off periods.
An electromagnet deflector had no effect on GM count rates produced with a D2+O2 glow discharge on a Pd cathode or with an O2 glow on a Pd cathode. The electromagnet did affect count rates of beta particles from a 14C source in vacuum as well as in 2 Torr of O2. Count rates for 14C were reduced by 50% with 1A magnet current and by 80% with 2A magnet current.
We believe the data observed in our series of experiments is consistent with the generally accepted mechanisms for production of Bremsstrahlung and Oxygen K-line x-rays. In particular, we are satisfied that the magnetic deflector tests rule out significant production of anomalous energetic electrons in our experiments, and that both our CR-39 results and Si barrier detector results rule out any significant production of heavier energetic particles. If any anomalous radiation was produced, it was below the sensitivity threshold of our detection systems.
