Ep. Zhidkov et al., COMPUTATION OF THE MAGNETIC-FIELD OF A SPECTROMETER IN DETECTORS REGION, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 365(2-3), 1995, pp. 308-316
Computed results of the 3D magnetic field of a spectrometer intended f
or investigation of hadron production of charmed particles and the ind
ication of the narrow resonances in neutron-nucleus interactions are p
resented. The methods used in computations: finite element method and
finite element method with suggested new infinite elements are describ
ed. For accuracy control the computations were carried out on a sequen
ce of three-dimensional meshes, Special attention is devoted to behavi
our of the magnetic field in the basic detectors (proportional chamber
s) region. The performed results can be used for the field behaviour e
stimate of similar spectrometer magnets.
