Abstract

The invention belongs to the field of isotope mass spectrometer manufacturing, and particularly relates to a mass spectrometer electromagnet which comprises a C-shaped yoke, an upper pole shoe coil, a lower pole shoe coil, a left fixing hook and a right fixing hook. The upper pole shoe coil and the lower pole shoe coil are respectively connected with an upper panel and a lower panel of the C-shaped yoke; the C-shaped yoke has high mechanical structural strength and is not prone to deformation, the problem that too many holes are punched due to connection is solved, and meanwhile errors caused by installation are reduced compared with the prior art. The pole shoe coil body can be stably and reliably fixed on the yoke through the fixing hook, the supporting adjusting piece and the pole shoe pad, and the installation requirement of a large-scale overweight electromagnet can be met.

Description

technical field [0001] The invention belongs to the field of isotope mass spectrometer manufacturing, in particular to a mass spectrometer electromagnet. Background technique [0002] The mass spectrometer electromagnet is the main body of the mass spectrometer, also known as the mass analyzer. Its principle is to use ions to move in the magnetic field generated by the electromagnet, which will be deflected according to the mass-to-charge ratio to achieve isotope mass separation. The magnetic mass analyzer has uniform and non-uniform magnetic fields, and the shape of the pole piece is cylindrical, fan-shaped, etc., and the shape of the overall structure is various. At present, the electromagnet structure widely used in mass spectrometers is a C-shaped structure. It is mainly composed of fan-shaped pole shoes, wire bags and yokes. According to the understanding of the electromagnets of the mainstream magnetic mass spectrometers of different companies, the yoke iron is gene...
