  1. Front-end and VME / VXI readout electronics for ASICs Ch. THEISEN – CEA Saclay Christophe.theisen@cea.fr - Christophe THEISEN - INTAG Workshop GSI

  2. Context • ASICs and readout electronics for the MUSETT Silicon detectors and other Si strip detectors (MUST II, annular Silicon detector for Coulex) • Large number of channel. Integrated electronics mandatory (MUSETT = 1024 channel). - Christophe THEISEN - INTAG Workshop GSI

  3. Electronics for one MUSETT detector Analogue Bus MUVI or CVM (x4) COFEE (x4) LV 4 Readout ATHED Trigger CAEN SY 2527 Slow Control HV I2C 64 128 + 128 strips Slow Control Slow Control Silicium Cooling LAUDA Proline RP 845 C - Christophe THEISEN - INTAG Workshop GSI

  4. ASICs : ATHED (Saclay design) Based on MATE ASICs for MUST II - Christophe THEISEN - INTAG Workshop GSI

  6. Front-end electronics : COFEE (IPNO design) • COulex Front-End Electronics • Based on MUST II MUFEE • 4 ASICs / board • 1 analogue bus / ASIC • Size 12 x 5 cm2 • Slow control : I2C • Provides HV to detectors (daughter boards) - Christophe THEISEN - INTAG Workshop GSI

  7. Readout • Two readout for MUSETT • Laboratory DAQ : CVM VME cards : “light” acquisition • Experiment DAQ : MUVI VXI cards : for GANIL environment - Christophe THEISEN - INTAG Workshop GSI

  8. CVM VME card (Saclay design) • Multipurpose card for ASICs readout • 4 analogue bus input = 4 ASICs with COFEE = 64 channels • USB slow control through STUC probe (Cypress micro controller, Virtex II FPGA). • VME or USB readout • Possibility to correlate VME cards (front panel trigger signals and clock). • 14 bits ADCs • 48 bits timestamp (100 MHz) Status: • Two prototypes tested • VME readout in progress • Waiting for Cofee front-end electronics before production. - Christophe THEISEN - INTAG Workshop GSI

  9. CVM - Christophe THEISEN - INTAG Workshop GSI

  10. CVM slow control and DAQ • LabView, VHDL, C daemon. XML data output. Root tools to be developed - Christophe THEISEN - INTAG Workshop GSI

  11. - Christophe THEISEN - INTAG Workshop GSI

  12. MUVI (Ganil design) • MUST VXI • 4x4 analogue bus input. • For 4 Cofee cards (16 ASICs) = 128 strips = 1 MUSETT detector (for 4 MUST II detectors since 1 bus/Mufee) • CAS mezzanine converter • Free running mode : all bus running independently and trigger-less • Time stamp with ATOM / GAMER / CENTRUM cards (48 bits, 10 ns resolution). • Full integration into the GANIL DAQ – DAS GUI - Christophe THEISEN - INTAG Workshop GSI

  13. MUVI ATOM CAS - Christophe THEISEN - INTAG Workshop GSI

  14. Status • ASICS ready • Cofee being tested • CVM being tested. Next : tests with Cofee • Test of Si + Cofee + CVM soon • MUVI ready for production - Christophe THEISEN - INTAG Workshop GSI
