5. University of Liverpool Nuclear Physics Computing Support Group Storage Example - SDLT SDLT600 Q4 2003 300GB >32MB/sec SDLT1200 2004 600GB >50MB/sec SDLT2400 cir 2006 1.2TB >100MB/sec AGATA GLP

6. TDR = Total Data Readout Every parameter treated independently and collected in ”singles”. TimeStamp included with every parameter. Leads to a higher data rate. Requires software filtering equivalent to conventional hardware master trigger. University of Liverpool Nuclear Physics Computing Support Group TDR Introduction

7. University of Liverpool Nuclear Physics Computing Support Group GREAT Schematic

8. University of Liverpool Nuclear Physics Computing Support Group GREAT Data Format

9. GREAT EB currently supports … Detector specific filters BGO filter Recoil coincidence filter Event definitions University of Liverpool Nuclear Physics Computing Support Group Data Filtering

10. Similar if ancillary detectors in use. Ge detector info more complex due to position information. Events can overlap. Delayed Event components ? University of Liverpool Nuclear Physics Computing Support Group Relation to AGATA
