Patent number: 11808695Abstract: A single ion imaging-based detection method and device are provided. After being reflected by an electromodulation singularity coupling differential imaging reaction unit, a probe beam from a total internal reflection ellipsometry imager converges on a CCD or CMOS detector, the acquired sensing surface image data is transmitted to a signal processing unit, the common mode noise is eliminated by performing spectral analysis on differential signals of a working sensing surface and a reference sensing surface, the peak intensity of a modulating signal is selected on the spectrum for wave filtering to obtain a real-time signal of interaction of single ions or charged molecules at a solid-liquid interface. Based on the singularity effect at a surface plasma resonance angle of an ellipsometry phase and a corresponding optical signal noise suppression scheme, the present application can achieve real-time observation of the adsorption of single ions or charged molecules at a solid surface.Type: GrantFiled: March 22, 2022Date of Patent: November 7, 2023Assignee: INSTITUTE OF MECHANICS, CHINESE ACADEMY OF SCIENCESInventors: Wei Liu, Yu Niu, Ziren Luo

Patent number: 11810686Abstract: Atom-scale particles, e.g., neutral and charged atoms and molecules, are pre-cooled, e.g., using magneto-optical traps (MOTs), to below 100 ?K to yield cold particles. The cold particles are transported to a sensor cell which cools the cold particles to below 1 ?K using an optical trap; these particles are stored in a reservoir within an optical trap within the sensor cell so that they are readily available to replenish a sensor population of particles in quantum superposition. A baffle is disposed between the MOTs and the sensor cell to prevent near-resonant light leaking from the MOTs from entering the sensor cell (and exciting the ultra-cold particles in the reservoir). The transporting from the MOTs to the sensor cell is effected by moving optical fringes of optical lattices and guiding the cold particles attached to the fringes along a meandering path through the baffle and into the sensor cell.Type: GrantFiled: August 2, 2021Date of Patent: November 7, 2023Assignee: ColdQuanta, Inc.Inventors: Dana Zachary Anderson, Clifton Leon Anderson

Patent number: 11791150Abstract: The resolution of a TOF mass analyzer is maintained despite a loss of resolution in one or more channels of a multichannel ion detection system by selecting the highest resolution channels for qualitative analysis.

Patent number: 11791146Abstract: Systems and multiplexing methods for measuring the mass of multiple large molecules simultaneously using multiple ion trapping with charge detection mass spectrometry (CDMS) are described. The methods trap ions with a broad range of energies that decouple ion frequency and m/z measurements allowing energy measurements of each ion throughout the acquisition. The ion energy may be obtained from the ratio of the intensity of the fundamental to the second harmonic frequencies of the periodic trapping oscillation making it possible to measure both the m/z and charge of each ion. Because ions with the exact same m/z but different energies appear at different frequencies, the probability of ion-ion interference is significantly reduced. By maximizing the decoupling of ion m/z from frequency, the rate of signal overlap is significantly reduced making it possible to trap more ions and substantially reduce analysis time.Type: GrantFiled: September 2, 2021Date of Patent: October 17, 2023Assignee: THE REGENTS OF THE UNIVERSITY OF CALIFORNIAInventors: Evan R. Williams, Conner C. Harper, Andrew G. Elliott
