Abstract :
One of the TRISTAN insertion quadrupole magnets was yoked and tested. The original magnet was an iron free magnet. The magnetic field measurements of the original and the yoked magnets were performed at 4.2 K. The transfer functions of the original and yoked magnets were measured and compared. The multipole fields as a function of axial position and magnet current are presented for the both magnets.
