摘要： A gas discharge chamber that uses a calcium fluoride crystal which reduces a breakage due to mechanical stress (window holder and laser gas pressure), thermal stress from light absorption, and the like, increases the degree of linear polarization of output laser, and suppresses degradation due to strong ultraviolet (ArF, in particular) laser light irradiation. A first window (2) and a second window (3) of the gas discharge chamber have an incident plane and an emitting plane in parallel with a (111) crystal plane of their calcium fluoride crystal. With respect to an arrangement where laser light entering the calcium fluoride crystal passes through a plane including a axis and a axis of each of the first window (2) and the second window (3) as seen from inside the chamber (1), the first window (2) and the second window (3) are arranged in positions rotated in the same direction by the same angle about their axis.

摘要： Objects of the present invention is to provide a quadrupole mass filter that can be fabricated at low cost and has a high transmission efficiency even under a high pressure (0.5 mTorr or more), and to provide a mass spectrometer or mass spectrometry method that reduces crosstalk in a wide mass range. Now, in a mass spectrometer, an ion separating unit is configured to include quadrupole rod electrodes that form a quadrupole radio-frequency electric field, electrodes that form a quadrupole electrostatic field, and a power supply that allows the voltage of the electrodes to form a quadrupole electrostatic field to change. In a collision cell configured to perform collision induced dissociation, harmonic potentials in a plurality of stages are produced to resonance excite ions in the axial direction, so that the ions obtain kinetic energy to move in the direction of the detector. This energy allows a time period to shorten for which ions stay in the collision cell.
