Abstract
This paper reports on the magnetic field mapping performed on the HRS spectrometers of Hall A, which are of QQDQ type. The dipoles were measured with a set of Hall probes in the symmetry mid-plane. The quadrupoles were measured inside their whole volume by a set of axially segmented rotating coils. High accuracy has been reached in both cases. Dipoles and quadrupoles were measured for a set of excitation currents covering the operating momentum range of the HRS: 0.5–4 GeV/c. The main results on field determination are presented.
