EGEE'09, Barcelona, September 23th, 2009
International Accelerator Facility forBeams of Ions and Antiprotons at DarmstadtFAIR will be located in Darmstadt, Germany,
adjacent to the existing GSI facility
Darmstadt lies in the Germanprovince called "State of Hesse"and is located near Frankfurt –just 20 minutes from the airport
GSI is the German heavy ionresearch centre operated by theFederation and the State of Hesseunder the umbrella of Helmholtz.Budget: roughly 70M€ / year

Each collaboration may involve a few dozen or a few
hundred scientists. Some experiment set-ups are small,
others will cost ca. one hundred million euros.
International Accelerator Facility forBeams of Ions and Antiprotons at DarmstadtThe FAIR project is a true "bottom-up" project
developed by thousands of scientists First ideas in the 1990s► GSI researchers began
discussions together with the outside users
Elaboration of design in 2001► GSI had drawn up the Conceptual
Design Report (CDR) for the new facility
Definition of "The Project" in 2006► 2500 authors submit the "FAIR
Baseline Technical Report" (FBTR) which defines the project

Timeline
International Accelerator Facility forBeams of Ions and Antiprotons at DarmstadtFAIR – will be built by an international collaboration, it costs
~1.2 billion € (75% Germany, 25% partner, partly in kind)

International Accelerator Facility forBeams of Ions and Antiprotons at DarmstadtTriggerless detector read-out: 1TB/s into an event
filter farm with ~60k cores, 1GB/s to archive► The current paradigm for ICT-based data analysis in high-energy physics relies on trigger
systems.► Trigger systems use simple criteria to rapidly decide which "interesting" events in a
particle detector to transport to further data processing and archiving stages. Trigger systems were necessary due to real-world limitations in data transport and processing bandwidth.
► At FAIR a novel triggerless detector read-out will be implemented without conventional first-level hardware triggers, relying exclusively on event filters.
► This new approach allows to address more complicated physics signatures which require complex algorithms, like a full track reconstruction, or information from many detectors systems for evaluation → more flexibility, more discovery potential.
► The first layer of the system constitutes the first-level event selector (FLES). The FLES implements a combination of specialized processing elements such as GPUs, CELL or FPGAs in combination with COTS computers, connected by an efficient high-speed network. After the FLES the data stream fans out into an archival system and into the next distributed processing layers, which can be off-site.
