Abstract
The spectrometric magnet is widely used in experiments on highenergy physics and a number of other fields. In this report, we present the results of calculating the magnetic field for a variant of a magnet with an interpolar gap of 0.13 m. Our spectrometer magnet has external dimensions of 2.95 x 2.12 x 1.62 m and an aperture (occupied by the beam) of 0.30 x 0.13 m. The simulation was carried out using an integral method of magnetostatics. The results of the calculated field distribution of the analyzing magnet with interpolar 0.13 m gap are given. The calculation was performed for the volume 0.33 x 0.0645 x 1.5 m, the volume of overlapping dimensions. The calculation of the spatial distribution of the three components of the magnetic field of the magnet described in the work is performed to obtain the information about the magnitude and uniformity of the magnetic field for different modes of operation of the spectrometer. The obtained results are planned for using in the processing of physical data.
Highlights
In mathematical modeling of the field distribution of various magnetic systems of electrophysical installations, differential formulations of the magnetostatic problem are actively used [1]
The magnetic field of the analyzing magnet was calculated in a spatial volume with dimensions of 0.35 x 0.10 x 2.18 m
A three-dimensional map of the distribution of all components of the magnetic field vector was compiled by volume
Summary
In mathematical modeling of the field distribution of various magnetic systems of electrophysical installations, differential formulations of the magnetostatic problem are actively used [1]. We consider the problem of magnetostatics in the integral formulation. The integrated formulation is chosen because of the ability to perform calculations on the grid only inside the ferromagnetic core. The center of the spectrometric magnet is taken as the beginning of the Cartesian coordinate system (the "right" triple XYZ) of the spectrometer. The described calculation of the spatial distribution of the three components of the magnetic field of the magnet was carried out in order to obtain the information on the magnitude and homogeneity of the magnetic field and to build a working field map for various operating modes of the spectrometer. It is planned to use these results in the processing of physical data
