  • Patent number: 11991814
    Abstract: Systems and methods of charge-neutralizing charged particle beams are contemplated, wherein an originating beam is transited through a sequence of slow wave recombination chambers and exposed to neutralizing beams while transit therethrough in order to produce a neutral particle beam. These systems and methods may be seen to be especially suitable for use in spacecraft or other ungrounded environments where the removal of excess charge buildup represents a substantial barrier, and when utilized in a directed energy weapon, may greatly increase the rate at which successive beam pulses may be directed against a target or against multiple targets.

  • Patent number: 11990326
    Abstract: In a mass spectrometer including ion optical elements for transporting ions or controlling their behavior by electric fields, a device state determiner (41, 52) determines whether or not the mass spectrometer is in a normal state based on an ion intensity signal acquired by analyzing a predetermined sample. If the mass spectrometer is in an abnormal state, a charge-up determiner (42, 53) determines whether or not charge-up is present in the ion optical elements based on a change in ion intensity signal in an analysis on the predetermined sample observed when the voltages applied to the ion optical elements are changed according to a predetermined sequence. If charge-up is present, the charge-up determiner determines which ion optical element is likely to have the charge-up. A notifier (8, 61) notifies a user of the results of the determination by the device state determiner and the charge-up determiner.

  • Patent number: 11971256
    Abstract: A guided cold-atom inertial sensor system comprises an atom trap integrated platform, a laser system, a magnetic field system, a control system, and a computing system. The laser system and magnetic field system are adapted to form a magneto-optical trap (MOT) about a suspended waveguide of the atom trap integrated platform made of membrane integrated photonics. After loading cold atoms from a MOT, the photonic atom trap integrated platform generates one-dimensional guided atoms with an evanescent field optical dipole trap (EF-ODT) along the optical waveguide to create guided atomic accelerometers/gyroscopes. Motion of atomic wavepackets in a superposition state is created along the guided atom geometry by way of state-dependent momentum kicks. The light-pulse sequence of guided atom interferometry splits, redirects, and recombines atomic wavepackets, which allows measurement of atom interference fringes sensitive to inertial forces via a probe laser.

  • Patent number: 11397085
    Abstract: A matter-wave gyro with counter-propagating traps uses three-dimensional lattices formed of interference fringes from three pairs of interfering laser beams. Particles, such as neutral atoms, ion, or molecules are cooled to a ground state near absolute zero. The resulting ultra-cold particles are loaded into the lattices. The laser beams used to form the lattices are driven according to functions that cause the lattices to counter-propagate about a closed path (Sagnac loop) N times, where a desired tradeoff between spatial resolution and temporal resolution can be achieved by choosing an appropriate integer value of N. The lattices can be extinguished so that the particles can be imaged to identify an interference pattern. A shift in the interference pattern relative to an interference pattern that would occur with zero angular momentum can be used to measure angular momentum.

  • Patent number: 11355334
    Abstract: Methods and systems are provided herein for selectively removing product ions resulting from an ECD dissociation event from the interaction region of an ECD reaction cell, while other precursor peptide ions continue to undergo ECD within the interaction region, thereby reducing or preventing the occurrence of multiple electron capture events by the product ions. In some aspects, the preferential extraction of product ions from the interaction region during the ECD reaction can occur without an auxiliary AC field being generated within the interaction region. Additionally, in some aspects, the methods and systems disclosed herein can subject the various product ions to a non-dissociative charge reduction via exposure to reagent ions of the opposite polarity so as to selectively concentrate product ions to a lower charge state.
