Abstract:
Disclosed is a gas separation arrangement for separating and containing various types of gas from a collection chamber based on their different atomic masses. The chamber is connected to an ion diverter via a valve that when open permits the various types of gas to migrate from the collection chamber to an ionizer where the gas is ionized. The ionized gas is accelerated through an ion accelerator and dispensed into an ion deflector. The ion deflector comprises a magnetic field within a channel defined by a pair of split-pole magnets. The trajectory of the ions is based on the mass of the ions, which separates the ions. Multiple collectors are positioned at different locations on an exit side of the ion deflector to receive the different ions traveling along their respective trajectories.
Abstract:
Described herein are embodiments directed to a particle repelling helmet having particle mitigation system that keeps dust particles from going into the interior of the helmet. The helmet comprises a face vent that provides an unobstructed pathway between an external environment and a wearer's eyes, nose and mouth. A spacer arrangement connected to an inner side of the helmet provides a channel between the wearer's head and the inner helmet side. A fan blows air through the helmet, across the wearer's head and out the face vent and head receiving opening in the bottom of the helmet. Electrodes disposed along the edge of the face vent produce an electrostatic barrier that spans the face vent thereby further preventing charged dust from going into the helmet. The helmet can also comprise an ionizer that generates ions, which charges neutral dust particles that can be blocked by the barrier.
Abstract:
Disclosed is a segregating gas arrangement that generally comprises a gas segregation chamber, at least one cooling plate in the gas segregation chamber, and a carbon adsorber in an adsorption gas capturing chamber. The gas segregation chamber has a rim that when resting atop regolith defines a first interior environment. The cooling plates are in the gas segregation chamber, wherein the cooling plates are maintained at a first temperature above 5° K, which is a condensation temperature that higher temperature condensing gases will condense. The adsorption gas capturing chamber defines a second interior environment that is in communication with the first interior environment. The carbon adsorber is in the second interior environment and is maintained at a second temperature below 3° K. The carbon adsorber is configured to capture the low temperature condensing gas.
Abstract:
Disclosed is a He-3 detector arrangement that generally comprises a mass spectrometer that has an intake funnel configured to receive (sniff out) He-3 through an intake port directly from an open environment. The intake funnel is configured to direct the He-3 into the mass spectrometer. The arrangement further comprises a heating element configured to liberate the He-3 from regolith via heat. A mobile carrier is configured to position the intake port the regolith to obtain samples of the He-3.
Abstract:
Disclosed is a He-3 detector arrangement that generally comprises a neutron shield interposed between a thermal neutron source and thermal neutron detectors all resting on a metal platform. In operation, thermal neutrons from the thermal neutron source are emitted when the He-3 detector arrangement is on or near the ground. Some of the thermal neutrons from the neutron source backscatter from the regolith to the neutron detector where a baseline count level is registered. When He-3 is present in the regolith, some of the thermal neutrons are absorbed by the He-3, which reduces the detected count rate. When integrated with a rover, the He-3 detector is moved from place to place with the count rates at each location compared. In this manner, higher and lower levels of He-3 in the regolith can be mapped indicating target regions for mining the He-3.

Abstract:
Disclosed is a nanosecond neutron analysis and associated particle imaging system (NNA/API) and gamma ray detector arrangement (arrangement) that uses associative element detection of titanium, iron and oxygen to determine concentrations of ilmenite or other minerals in extra-terrestrial bodies associated with He-3. The arrangement is used with a mobile carrier for mapping out concentrations of likely He-3 regions on the extra-terrestrial body.
