Abstract
At the Dresden Radiation Source ELBE an intense IR beam in 3 - 30 µm range will be produced in the undulator U27. It consists of two 34-pole sections, allowing to insert a magnetic chicane in between. The undulator structure has a period of 27.3 mm and consists of NdFeB permanent magnets and poles of decarborized iron, mounted on two carriages such that the distance between the two sections is adjustable for phase-matching. The gaps of both sections can be varied independently to eventually produce two IR-colours at the same electron energy. For high-gain lasing one can introduce a tapering of the field.
Keywords: Hybrid undulator; hall probe measurement; pulsed wire method; field tapering; phase matching
