Magnets
The basic design of the HES spectrometer follows it of HKS. The HES consists of two quadrupole magnets (EQ1 and EQ2) and one dipole magnet (ED).Due to two degrees of freedom of the quadrupole doublet, the horizontal and vertical focusing can be adjusted simultaneously. The HES is designed to achieve both <math>2 \times 10^{-4}</math> momentum resolution and 8 msr solid angle acceptance at the same time when it is used with the Splitter. The HES magnets were constructed at TOKIN[1] (TOKIN machinary), Sendai Japan and shipped to JLab.
