Claim Text:
1. A sputter neutral particle mass spectrometry apparatus comprising: a sample table holding a sample which is a mass spectrometry target, and comprising a temperature control mechanism for the sample; an ion beam irradiation device which irradiates an ion beam on the sample held by the sample table to generate neutral particles; a laser irradiation device which irradiates the neutral particles with a laser to obtain photoexcited ions; a draw-out electrode which draws out the photoexcited ions; a mass spectrometer which draws in the drawn out photoexcited ions and performs mass analysis; a driving system mirror which is provided retractably on a laser light path between the laser irradiation device and the sample table, and reflects the laser when positioned within the laser light path; and a profiler which is arranged in a reflective direction of the driving system mirror and detects a feature of the laser.
