STATUS OF THE PETRA III INSERTION DEVICES

The PETRA storage ring is presently reconstructed towards a third generation light source. In total, 14 undulator beamlines will be available in the new octant of the machine. We report on the status of the Petra III undulators. Three prototypes with 29mm period length, two 2m and one 5m long device, have been investigated by mechanical and magnetic measurements. The prototype results are the basis for the refined design of the remaining 8 planar devices which are in the procurement phase. We present preliminary magnetic results of the prototypes and also report on the APPLE2 and the In- Vacuum undulator for PETRA III.
