	Superconducting wigglers are very popular devices for generation of the synchrotron radiation in the hard X-ray spectral range. The one direction of the future progress in wigglers development is reducing of the technical complexity wigglers design as well as technical service for cryogenic system. The BINP wigglers without liquid helium consumption were a noticeable milestone of these efforts. The next significant step toward additional simplification wiggler design and service is indirect cooling of the wiggler magnet. In this case the wiggler magnet not sinked into the liquid helium, but cooled by thermal connection link with the head of cryogenic cooler. This approach is used for design of the indirect cooled wiggler for IMAGE beamline on the ANKA light source (KIT, Germany). This wiggler also will be tested as a prototype for damping wiggler for the damping rings in the project of the Compact Linear Collider (CLIC) for CERN. This report summarizes some details of the wiggler design as well as a result of the short prototype testing.
