Andreas Galatis received his diploma in electrical engineering and information technology (Dipl.-Ing.) from the Darmstadt University of Technology in November 2003. His diploma thesis was on stereo echo cancellation at the Signal Theory Group at TUD. Since March 2004 he has been an external Dr.-Ing. candidate from GSI.

Research

Particle accelerator beam position monitoring using signal processing

Design and implementation of algorithms for beam position monitoring (BPM). In the GSI particle accelerator beam is formed in so called bunches, packets of particles. Their position inside the accelerator ring is a crucial information for the operation of it, since a position near to centre of the ring is desired. To obtain signals, capacitive coupled pick-ups are used equidistantly scattered around the ring. Parameters that should be estimated:

* bunch position: accuracy of ca. 100µm, speed minimum of 10MHz for turn-by-turn analysis

* bunch tracking at consecutive pick-ups for orbit tracking

* measurements of the Q-tune in betatron oscillation

* profile measurement etc

The project is part of preparatory work for a future project at GSI and is taking place in a wider collaboration with other facilities such as CERN and the Forschungszentrum Juelich.
