Accelerator Research and Development (ARD) at DESY
DESY is one of the world's leading accelerator centers and a member of the Helmholtz Association. DESY develops, builds and operates large particle accelerators used to investigate the structure of matter. Accelerator Research and Development (ARD) is a core mission of the lab.

The team for accelerator research and development (ARD) is located in DESY's accelerator division and the particle physics division and operates in strong collaboration with the accelerator physics at University Hamburg. It works on various critical R&D topics for particle accelerators, including the themes defined in the accelerator initiative of the Helmholtz Association. The ARD team at DESY performs studies on the following research topics:
- Super-conducting RF structures towards long pulse and continuous-wave operation as well as higher accelerating gradients. Contact: H. Weise, E. Elsen
- Generation of ultra-short, bright electron beams: from pico-second over femto-second to atto-second electron and light pulses. Contact: H. Schlarb, R. Assmann, F. Stephan, K. Flöttmann
- Concepts and realization of innovative plasma particle accelerators: towards next-generation linear accelerators with accelerating gradients of above 1 Giga-Volt per meter. Contact: R. Assmann, F. Grüner, J. Osterhoff, E. Elsen, B. Hidding, F. Stephan
- Developments and optimization of Free-Electron Lasers (FEL´s): optimizing FEL operation with different seeding schemes. Contact: R. Assmann, J. Rossbach
- Ultimate storage rings: reaching diffraction-limited emittances in circular rings. Contact: R.Wanzenberg
- Future colliders for particle physics (i.e. Higgs factory, ILC, ...). Contact: R. Assmann, N. Walker, B. Foster, E. Elsen.
Diagnostics of conventional and advanced beams. Contact: B. Schmidt
Super-conducting technology R&D in the DESY accelerator division is mainly coordinated by Hans Weise, warm accelerator R&D mainly by Ralph Aßmann. Progress is discussed in common meetings. The work on plasma acceleration is performed in LAOLA, a collaboration between DESY and University Hamburg.

Remarks on Accelerator R&D in Germany and Inspiration
Accelerator research in Hamburg is performed in a long and very successful collaboration between DESY and the University Hamburg. In future, the collaboration will be called the "Voss Wideröe Center for Accelerators", a competence field of PIER.
Critical concepts for particle acceleration have been invented by R. Wideröe (* 11. July 1902 in Oslo, Norway; † 11. October 1996 in Nussbaumen, Switzerland) during the 1920's in Germany. In his legendary 1927 PhD thesis of 27 pages in Aachen he achieved two breakthroughs: (1) Invention and experimental setup of the first RF linear accelerator and (2) first idea for circular accelerator inspiring Lawrence for the invention of the cyclotron.
