1. Ancillary Detectors Working Group Agata Week/GSI, 23 Feb. 2005 Integration of ancillaries with DAQ Goal Context Specifications, modes Design Schedule & cost Ch. Theisen for the ADWG ctheisen@cea.fr

2. Ancillary Detectors Working Group Agata Week/GSI, 23 Feb. 2005 Goal Integration of ancillary detectors electronics with Agata Provide an interface  As many ancillary detectors as possible !

3. Ancillary Detectors Working Group Agata Week/GSI, 23 Feb. 2005 Context When: for the demonstrator phase (2007) Where: Ganil, GSI, JYFL, Köln, LNL Who: Existing and/or identified ancillaries  ADWG meeting 22/06/2004  LUSIA, FRS, RFD, Neutron Wall, CUP, VAMOS, PRISMA, GREAT,…, γ arrays  List to finalize a.s.a.p…

4. Ancillary Detectors Working Group Agata Week/GSI, 23 Feb. 2005 LUSIA FRS RFD Neutron Wall

5. Ancillary Detectors Working Group Agata Week/GSI, 23 Feb. 2005 CUP VAMOS PRISMA RITU/GREAT

6. Ancillary Detectors Working Group Agata Week/GSI, 23 Feb. 2005 Specifications  Correlate ancillaries with Agata (event number and/or clock counter)  Event filtering Keep relevant Agata and ancillary det. events “Slow-down” Agata Reduce ancillary det. dead-time  Interaction with AGATA GTS

8. Ancillary Detectors Working Group Agata Week/GSI, 23 Feb. 2005 Interface with GTS GTSAncillary Trigger Request Val/Rej, Clock Val/Rej : combination of ancillary/Agata : “master”, “slave”, “mixed” modes Latency times  NOT A TRIGGER MODULE !

9. Ancillary Detectors Working Group Agata Week/GSI, 23 Feb. 2005 Latency times Val/Rej : latency > 7μs Too late for most converters  Dead time !  Need prompt pre-trigger  Request to ADP : Agata prompt signal

10. Ancillary Detectors Working Group Agata Week/GSI, 23 Feb. 2005 Global scheme Ancillary Front-end Ancillary Readout VME interface Trigger Request Val/Rej Clock counter Event Number GTS supervisor Agata Merge/ Ancillary post-merge Agata flow Agata prompt signal

11. Ancillary Detectors Working Group Agata Week/GSI, 23 Feb. 2005 Three modes “Slow” conversion mode (common dead time) “Fast” conversion mode (parallel-like) Trigger-less (TDR)

14. Ancillary Detectors Working Group Agata Week/GSI, 23 Feb. 2005 TDR (JYFL) mode Correlated data (DSSD, Gas) : Trigger request Uncorrelated data (Tunnel, Focal plane Ge…) No events: only data  Time Stamping Clock counter correlation ! TDR clock counter GTS clock counter  Embedded TDR data source

15. Ancillary Detectors Working Group Agata Week/GSI, 23 Feb. 2005 TDR mode Interface provides 100MHz clock Embedded TDR data source –Phase calibration –Time-stamp synchronisation –Time-stamp alignment  Interface with TDR metronome  Shark link
