The activities of expert group 4 are focused on the optimization and required R&D work on the FAIR accelerators. The proposed tasks address specific R&D topics that are important for the FAIR accelerator systems and for new ion acceleration methods.
The linac activities concentrate on cavity and beam transport developments, focussing on high brightness beams and high electric fields for efficient acceleration of intense beams. Concerning high current synchrotrons, beam dynamics, RF-systems and cavities, diagnostics and beam losses including the related material science question are the main topics. One of the main differences between the RF-control of SIS18 compared to the FAIR machines is the variety and number of RF cavities that have to be synchronized. Furthermore, longitudinal beam stabilization has to be investigated to validate the existing longitudinal feedback concepts for an application in the scope of the FAIR project.
Overlap with the APPA collaboration include the target techniques for storage-ring, charge exchange processes in rings, diagnostics and materials for high current ring accelerators. Finally the expert group investigates laser driven ion beam acceleration as a new concept in detail. This investigation needs new simulation tools to describe the extremely dense particle distribution involved during generation and transport along the very first micrometers, millimeters and centimeters.
Oliver Boine-Frankenheim - Leader of Expert Group 4
Oliver Boine-Frankenheim, Professor in the Electrical Engineering and IT Department at the Technische Universität Darmstadt, is the leader of the Expert Group Accelerator in HIC for FAIR. He was born in Düsseldorf in 1968. He received his doctoral degree from the Technische Universität Darmstadt in 1996. Afterwards he worked as a postdoc at Sandia National Laboratories, USA and at GSI, Darmstadt, where he is presently the beam physics department head. He was appointed as a (tenured) Professor for Accelerator Physics in 2011 at the Technische Universität Darmstadt.
His main research topics are beam physics in the FAIR accelerators, the physics of intense particle beams and the numerical simulations of such beams in accelerators, the study of plasma-based particle acceleration mechanisms and the subsequent beam transport.
He is the vice-chair of the German 'Komitee für Beschleunigerphysik' (KfB) and a board member of the EPS accelerator group (EPS-AG)
