  1. present status • test results • with AGATA@GSI Lund York Cologne Calorimeter Thanks to Andreas Wendt !!

  2. Reminder: Detection principle LYCCA-0 ΔE-E-hardware: 12 DSSDs 12x9 CsI (long/short) Sekundary target DSSD Diamond or Plastic DSSD CsI RIB vom FRS (x, y) Time-of-Flight (ΔE, x, y) (E) AGATA @ GSI meeting May 4th 2010, Is University of York Mike Bentley University of Cologne Andreas Wendt

  3. Reminder: Detection principle 37Ca (85 %) 2*103 p/sec 36K (10 %) Double fragmentation reaction: 40Ca (420 MeV/u) + 9Be (4.0 g/cm2) → 37Ca (196 MeV/u ) + 9Be (0.7 g/cm2) Selection by CATE (Energy-loss/Energy) Selection by FRS AGATA @ GSI meeting May 4th 2010, Is University of York Mike Bentley University of Cologne Andreas Wendt

  4. Reminder: Detection principle Simulation: M.J.Taylor et al (assumes 3m flight path and 50ps FWHM)) Mass Selection by Time-of-Flight and Energy • Expected performance: Mass identification (if ~50ps FWHM timing achieved) • Mass separation up to A~70 • Some mass information at A~100 • Depends on specific case (needs simulation) AGATA @ GSI meeting May 4th 2010, Is University of York Mike Bentley University of Cologne Andreas Wendt

  5. Status: mechanics LYCCA chamber: • up to 72 KEL-Feethroughs • 32 SHV+Lemo-FT Vacuum test @ cologne (5·10-5mbar) Feb. 2010 Used as TKE-detector (for S272 @ S4) Mar./Apr. 2010 Preparation and storage @ X7 AGATA @ GSI meeting April 30th 2010, GSI University of York Mike Bentley University of Cologne Andreas Wendt

  6. Status: Silicon detectors • - 32 x 32 strips • - Active area 58 x 58 mm² • - Interstrip distance : 75 μm • thickness: 300 μm • 12 ΔE-detector needed for LYCCA-0 • Ordering status: • 18 DSSDs delivered • all T-boards delivered • connectors on-hand • ΔE-detector status: • 10 DSSDs ready! • 8 @ Lund, awaiting bonding • [2 ΔE-detectors tested in-beam] AGATA @ GSI meeting April 30th 2010, GSI University of York Mike Bentley University of Cologne Andreas Wendt

  7. Status: CsI-scintillators short 40.0 long • „short“ crystals (13+7mm) • 2 E-Blocks assembled, tested • crystals for another 4 blocks available • mechanics for 12 E-Blocks available • „long“ crystals (33+7mm) • crystals for 13 E-Blocks on hand • 4 E-Blocks (used for S272) ready AGATA @ GSI meeting April 30th 2010, GSI University of York Mike Bentley University of Cologne Andreas Wendt

  8. Status: Time-of-flight PLASTIC • Detector constructed for ToF-stop • - New one being constructed for ToF-start • Stop-detector tested in-beam (GSI) • 300 MeV/u 58Ni SC42 180ps FWHM Plastic ToF 40ps FWHM Robert Hoischen et al (Lund/GSI) AGATA @ GSI meeting April 30th 2010, GSI University of York Mike Bentley University of Cologne Andreas Wendt

  9. Status: Time-of-flight DIAMOND • Start-detector: 9 x PC 2x2cm wafers (4 strips) • 36 detector segments • Prototype wafers fabricated and tested • 5 wafers will be put in detector in June/July 2010 • Fast DBAIV current pre-amps + V1290 TDC • First tests TEXAS A&M March/April 2010 • ~35MeV/u 40Ar beam • ~20 MeV/u 20Ne beam AGATA @ GSI meeting April 30th 2010, GSI University of York Mike Bentley University of Cologne Andreas Wendt

  10. Status: Time-of-flight DIAMOND ~35MeV/u 40Ar beam Best ~90ps FWHM Best achieved ~90ps FWHM ~20 MeV/u 20Ne beam • BUT • …problems with detector reliability (HV breakdown, PCB?) • …and fabrication consistency. 16O 20Ne AGATA @ GSI meeting April 30th 2010, GSI University of York Mike Bentley University of Cologne Andreas Wendt

  11. Time-of-flight for AGATA • Two options: • Diamond start AT TARGET (~70ps FWHM required) and Plastic stop (50ps ideal) • OR.. • Plastic start UPSTREAM OF TARGET (~50ps FWHM required) and Plastic stop (50ps ideal) • THESE will be tested in June/July 2010 Plastic DSSD DSSD CsI Plastic Diamond Secondary target Time-of-Flight (ΔE, x, y) (E) (x, y) AGATA @ GSI meeting April 30th 2010, GSI University of York Mike Bentley University of Cologne Andreas Wendt
