	In this contribution we report on the spectra calculated from the field measurements performed in a liquid helium bath of 1.5 m superconducting undulator coils. The coils are foreseen for a superconducting undulator demonstrator with a period length of 15 mm planned to be installed in ANKA middle 2012 and tested at the new beamline NANO for high resolution X-ray diffraction. The spectral performance at ANKA and at low emittance sources is compared with the competing cryogenic permanent magnet technology.

	Switching the period length allows to increase the tunability of an insertion device. This can be realized in superconducting insertion devices (IDs) by reversing the current in a separately powered subsets of the superconducting windings. In order to use only one power supply instead of two for the two circuits, reducing the thermal input to the device, work is ongoing at ANKA to develop a superconducting switch. In this work we present the results of the test of an in-vacuum housed, conduction-cooled superconducting switch.

Switching the period length allows to increase the tunability of an insertion device. This can be realized in superconducting insertion devices (IDs) by reversing the current in a separately powered subsets of the superconducting windings. In order to use only one power supply instead of two for the two circuits, reducing the thermal input to the device, work is ongoing at ANKA to develop a superconducting switch.
