Development of the In-vacuum APPLE II Undulators at HZB | |
|
||
| HZB is working on a concept for BESSY III, the successor to BESSY II. It is planned to be a 4th generation synchrotron light source with an emittance of about 100 pm rad and an energy of 2.5 GeV. BESSY III will be equipped with advanced undulators to provide users with tailor-made light. Since polarisation control in the soft X-ray region is important for BESSY users, a variety of APPLE II undulators are planned, such as conventional (in-air), in-vacuum, cryogenic in-vacuum and double-period in-vacuum APPLE undulators (DoPUs). HZB has a long and successful tradition in the design, construction, and operation of conventional APPLE II devices. Currently, the first in-vacuum APPLE II undulator (IVUE32) is being built at HZB. In addition, the technical design of the cryogenic version of the In-Vacuum APPLE II (Cryo-APPLE) is progressing; construction will start at HZB in the next few years. This paper reports on the status of the In-Vacuum APPLE II and the Cryo-APPLE and outlines future development plans. | ||
