Abstract

The superconducting dipole and quadrupole magnets for the proton-electron collider HERA are subjected to extensive tests including measurements of heat loads, helium leak rates, maximum field capability, field integral, field direction and field uniformity. The magnets measured so far exceed the design performance by a safe margin.
