  • Patent number: 11398375
    Abstract: A mass spectrometry system includes a sample holder provided in a vacuum changer and on which a sample is disposed, an irradiator configured to perform sputtering or ionization on the sample, an analyzer configured to analyze an ionized sample generated from the sample by the irradiator, and a controller configured to control the irradiator or the analyzer and perform a first process and a second process. The first process is to determine position information of materials in the sample by irradiating a laser or ion beam to a portion of the sample, and the second process is to irradiate a laser or ion beam of a first output value to another portion of the sample in a section in which the materials in the sample change and irradiate a laser or ion beam of a second output value in other sections.

  • Publication number: 20220157554
    Abstract: A mixed gas cluster ion beam generator may include a nozzle chamber to contain a first mixed gas which is a mixed gas that is a mix of a first gas and a second gas, a cluster nozzle to spray gas received from the nozzle chamber in a cluster form, an ionizer to ionize a gas cluster sprayed by the cluster nozzle, and an ion accelerator to emit an ion beam to the outside by accelerating the gas cluster ionized by the ionizer by generating a potential difference to the ionized gas cluster.

  • Patent number: 10699868
    Abstract: Disclosed is a device for generating an organic molecular cluster ion beam, the device including a receiver configured to accommodate an organic material, a cluster generator configured to generate a cluster by supersonic expanding the organic material accommodated in the receiver at a high speed, a photo-ionizer configured to temporarily accommodate the cluster that is generated through the cluster generator, an ultraviolet (UV) light source configured to irradiate an UV pulse to the photo-ionizer to ionize the cluster, and entrance electrodes disposed at both sides of the photo-ionizer and configured to provide a potential difference to the photo-ionizer to generate a cluster ion beam.

  • Publication number: 20200152410
    Abstract: An ion beam generating device includes a liquid metal ion source configured to melt metal and emit an ion beam, and an extractor disposed under the liquid metal ion source and configured to extract the ion beam emitted from the liquid metal ion source. The liquid metal ion source includes a storage configured to accommodate the metal, an emitter configured to receive the metal from the storage and emit the ion beam, and a heater configured to heat the emitter or the storage. The heater is configured to directly heat the metal accommodated in the storage to melt the metal into a liquid state, and an amount of the ion beam to be extracted is controlled by a voltage difference that changes based on a distance between the emitter and the extractor.

  • Publication number: 20070191060
    Abstract: A device and method for distinguishing selected line information among multi line information providing ALS (alternate line service). The device includes an SIM (subscriber identity module) for storing the selected line information among the multi line information providing the ALS service, in a file for storing support information of a CSP (customer service profile) on a data structure; and an ME (mobile equipment) for, upon insertion of the SIM, determining if the ALS service is supported from the SIM, and upon determining that the ALS service is supported, acquiring the selected line information from the file, and executing the ALS service based on the acquired line information.
