摘要： An atom probe includes a specimen mount that can hold a specimen to be analyzed. A detector is spaced apart from the specimen mount. Between the detector and specimen mount Is a local electrode with an aperture. A laser is oriented to emit a laser beam toward the specimen mount at a nonzero angle with respect to the aperture plane, the aperture plane being oriented perpendicular to an ion travel path defined through the aperture between the specimen mount and detector.

摘要： A laser atom probe situates a counter electrode between a specimen mount and a detector, and provides a laser having its beam aligned to illuminate the specimen through the aperture of the counter electrode. The detector, specimen mount, and/or the counter electrode may be charged to some boost voltage and then be pulsed to bring the specimen to ionization. The timing of the laser pulses may be used to determine ion departure and arrival times allowing determination of the mass-to-charge ratios of the ions, thus their identities. Automated alignment methods are described wherein the laser is automatically directed to areas of interest.

摘要： A method for aligning an energy beam to an object in an atom probe is disclosed. The method comprises monitoring at least one parameter indicative of an interaction between the energy beam and the object. A signal is generated in response to the interaction of the energy beam and the object. The signal is then used to effectuate control of the alignment of the energy beam to the object.

摘要： A laser atom probe (100) situates a counter electrode between a specimen mount and a detector (106), and provides a laser (116) having its beam (122) aligned to illuminate the specimen (104) through the aperture (110) of the counter electrode (108). The detector, specimen mount (102), and/or the counter electrode may be charged to some boost voltage and then be pulsed to bring the specimen to ionization. The timing of the laser pulses may be used to determine ion departure and arrival times allowing determination of the mass-to-charge ratios of the ions, thus their identities.
