Tracera Gas Chromatograph
Tracera provides high-sensitivity analysis of organic compounds, permanent gases and light hydrocarbons with the BID-2010 Plus, a novel universal detector that incorporates plasma technology. The BID creates ionization from a helium-based, dielectric barrier discharge plasma. Compounds that elute from the GC column are ionized by the helium plasma energy, detected by the collection electrode and processed as peaks. The BID enables trace impurity analysis with detection sensitivity more than 100... (read more)

Ion Energy Distributions for a DC Plasma (.pdf)
, which is generally part, or all of, the cathode electrode. It is important in plasma discharges, especially in ionization assisted deposition systems, to know the relationship between the ion energy transportation and the cathode fall length (or cathode sheath). This can help to optimise the plasma

The Cryogenic Dark Matter Search: First 5-Tower Data and Improved Understanding of Ionization Collection
2.2 Schematic of the CDMS-II ZIP detector configuration with 4 phonon sensors on the “top” face and 2 ionization electrodes on the “bottom” face. . . . . . .
The field- ionization electrode system is attached to the bottom plate of the mixing chamber of a dilution refrigerator and ionized electrons are transported to a channel electron multiplier at the 1 K temperature pumping stage through a series of ring focusing …
Studying the process of oxygen ionization on a porous metal hydride electrode
This is probably connected with the gas propagat- ing in the layered environment of the interelectrode gap in the form a jet that moves to the ionizing electrode ; in so doing, no substantial increase in the gas content of the matrix is …
