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).

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 GSICEA DSM Dapnia SPhNMay 25th, 2007 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 GSICEA DSM Dapnia SPhNMay 25th, 2007 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.

CVM
- Christophe THEISEN - INTAG Workshop GSICEA DSM Dapnia SPhNMay 25th, 2007 10
CVM slow control and DAQ
•LabView, VHDL, C daemon. XML data output. Root tools to be developed
- Christophe THEISEN - INTAG Workshop GSICEA DSM Dapnia SPhNMay 25th, 2007 11
- Christophe THEISEN - INTAG Workshop GSICEA DSM Dapnia SPhNMay 25th, 2007 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

Status
•ASICS ready
•Cofee being tested
•CVM being tested. Next : tests with Cofee
•Test of Si + Cofee + CVM soon
•MUVI ready for production
