The disclosure includes an ionization chamber, a first electron multiplier, and a second electron multiplier. The ionization chamber is configured to receive gas molecules from an environment at a pressure. The first electron multiplier is configured to receive a plurality of photons from a photon source, generate a first plurality of electrons from the plurality of photons, and discharge the first plurality of electrons into the ionization chamber to generate a plurality of gas ions from at least a portion of the gas molecules. The second electron multiplier is configured to receive the plurality of gas ions from the ionization chamber and generate a second plurality of electrons from the plurality of gas ions that is proportional to a quantity of the plurality of gas ions. A quantity of electrons of the second plurality of electrons is indicative of the pressure.

Fast pressure sensing system

In one embodiment, the present invention relates generally to a system for providing a flow through battery cell and uses thereof. In one embodiment, the flow through battery cell includes an inlet for receiving a flow of water, a solid oxidizer coupled to the inlet for reacting with the flow of water to generate a catholyte, wherein the solid oxidizer comprises at least one of: an organic halamine, a succinimide or a hypochlorite salt, a galvanic module coupled to the solid oxidizer for receiving the catholyte and generating one or more effluents and an outlet for releasing the one or more effluents.

Method and system for providing a flow through battery cell and uses thereof

A die assembly for creating a ring electrode including a cylindrically-shaped die base, two die walls and a die top sized to fit inside a cylindrical die housing. The die base and die top having a series of concentric elevations used as impressions to form on two ends of the ring electrode. A method of fabricating an LTCC ring electrode using the die assembly is also provided.

Fabrication of three-dimensional ion optics assemblies by metallization of non-conductive substrates

A cylindrical ion trap (CIT) mass spectrometer constructed using a non-conductive substrate (LTCC) as the basis for the ring electrode. Photolithography and electroless plating were used to create well-defined conductive areas on the LTCC ring electrode. The inventive method allows for the precise control of establishing conductive areas on a non-conductive substrate through the steps of punching, lamination, firing, metallization and photolithography on the metallized layer.

Fabrication of 3-D ion optics assemblies by metallization of non-conductive substrates

A portable mass spectrometer for underwater use includes a watertight case having an inlet and means for transforming an analyte gas molecule from a solution phase into a gas phase positioned within the case. Means for directing a fluid to the transforming means from the inlet and means for analyzing the gas-phase analyte molecule to determine an identity thereof are also positioned within the case.
