    "abstract": "During the last years several attempts were undertaken to decrease the period\nlength of undulators to the mm range. In this paper, a novel type of an\nin-vacuum undulator is described which is built with superconductive wires. The\nperiod length of this special device is 3.8 mm. In principle, it is possible to\ndecrease this period length even further. A 100 period long undulator has been\nbuilt and will be tested with beam in the near future.",
