Summary

In order to increase the luminosity of the TRISTAN electron-positron collider, eight superconducting quadrupole magnets are required. For this purpose, an iron-free quadrupole with a field gradient of 70 T/m was developed. Since they were commissioned in January 1991, the eight quadrupoles have been operated without trouble and luminosity has been about doubled. The total operating time of the magnets is currently about 10,000 hours. In the paper, a brief description of the magnets and the results of the tests, as well as the experience over the first two years of operation, are presented.
