The first pre-prototype of a single-coil superconducting miniundulator has\nbeen built and studied. Its basic specifications include 10 main periods and\ntwo end compensation periods, a period length of 7 mm, and a gap of 2 mm. The\ndesign is based on a racetrack-like coil configuration that is subsequently\ncompressed to form the gap region with the spatially alternating currents\nflowing perpendicularly to the electron beam above and below the midplane.\nOperation up to an excitation current slightly beyond 400 A before quenching\nresulted in a peak magnetic flux density on axis of about 1 T and an undulator\nparameter of K about 0.65.\n
