Abstract :
A short model of single-layer Nb3Sn common coil dipole magnet has been fabricated and tested at Fermilab. The paper summarizes results of magnetic measurements in the common coil model. The geometrical harmonics, coil magnetization and iron saturation effects, ramp-rate dependence, field decay and the "snap-back" effect at injection are presented.
