2 1 cm 3 CsI(Tl) + LAAPD Hamamatsu S Barrel prototype proposal

3  Realistic frustum-shaped crystals: Lanzhou Hilger St. Gobain (France and India) Scionix  LAAPDs Hamamatsu 2x(10x10) mm 2  Charge Pre-Amplifiers Cremat CR-110  VME Flash ADC Module MataCQ 32  VME based DAQ Materials

4 CsI(Tl) 13 cm LAAPD Hamamatsu S shapp.amp gammas CAEN V1729 CAEN V1729 shapp.amp protons VME crate GSI-MBS  Go4 NIM crate Electronic chain Dynamic range : < 10 4 Rate < 1kHz Sampling rate ~ 500 MS/s ?? Demonstrator meeting, Madrid May-09 Cremat CR110 Charge preamp

5 CREMAT CR-110

6 Four Preamps motherboard R3B/EXL meeting Milan Oct-06 Common bias supply

7 Hamamatsu prototypes Material  LAAPD from Hamamatsu  Active Area: 2 x (10 x 10) mm 2

8 Proposal for the prototype DAQ 1 or 2 GHz sampling frequency on each channel 300MHz bandwidth Analog to digital conversion on 12 bits Full dynamic range : V LSB of 250µV 2560 points per channel Integral non linearity : % Differential non linearity : % Sampling jitter < 20ps RMS Trigger datation with a precision of 50ps RMS Four first level trigger modes Two levels of trigger 32-bit VME and GPIB interfaces Peak power consumption below 25W MJ2 – main features Already ordered to:

9  Realistic frustum-shaped crystals: 2 from Lanzhou …………………………………… from Hilger …………………………………… from St. Gobain ………………………………… from Scionix ………………………………… 1280  LAAPDs Hamamatsu 5 pieces 2x(10x10) mm 2 …………………………… 5707 R&D …………………………  VME Flash ADC Module MataCQ 32 ( 4 channels) …………………………… ~ we can add crystals + PREAMP ~ Cost estimation

10  LAAPDs Hamamatsu 10 pieces 2x(10x10) mm 2 …………………………… VME DAQ MataCQ 32 ( 12 channels) …………………………… VME Crate ……………………………………………… 5000 RIO ……………………………………………………… TRIBA ……………………………………………………… ~ Still Missing
