2. INO TRIDAS activities at Mumbai B.Satyanarayana TIFR, Mumbai bsn@tifr.res.in INO Collaboration Meeting, VECC/SINP, Kolkata

3. Working groups • At TIFR • K.S.Gothe, Atul Jain, S.D.Kalmani, P.Nagaraj, B.K.Nagesh, S.K.Rao, L.V.Reddy, B.Satyanarayana and S.S.Upadhya • At BARC • V.B.Chandratre and Shanti Krishnan INO Collaboration Meeting, VECC/SINP, Kolkata

4. TRIDAS strategies • Test stand for detector R & D • Instrumentation for prototype detector • R & D and prototyping for full scale detector INO Collaboration Meeting, VECC/SINP, Kolkata

5. Test stand for detector R & D • VME based hardware from CAEN • Configuration • 21-slot 9U crate with CERN approved backplane • Power PC 604R 400 MHz controller, SCSI HD, Ethernet and console ports, Lynx-OS • VME modules • Scaler, I/O register, latch, qADC and TDC • Current status • System configured and setup • Basic readout trials and software development under progress INO Collaboration Meeting, VECC/SINP, Kolkata

6. Instrumentation for prototype detector • Detector size: 1m X 1m X 1m • 6cm thick absorber, 1cm thick detector • 14 detector layers, 28 detector readout planes • 50(20) strips or channels per readout plane for a pitch of 20(50)mm • Total channels are 1400(560) • Components: Discriminators, latches, TDCs, Trigger, Monitoring etc. INO Collaboration Meeting, VECC/SINP, Kolkata

7. Instrumentation for prototype detector (Cond.) • Approach • Use available resources and expertise • Quick solutions and short term goals • CAMAC based! • Two schemes developed • Non-FPGA based solution (S.S.Upadhya) • FPGA based solution (Shanti Krishnan) • To converge on one scheme soon (here!) and implement INO Collaboration Meeting, VECC/SINP, Kolkata

8. R&D and prototyping for full scale detector • Procurement of VLSI design tools at TIFR • Market survey in progress, indent to be placed soon • BARC’s expertise to be utilised • ASIC development and prototyping activity • V.B.Chandratre • Small sub-groups working on various sub-systems such as VME hardware design, trigger, high voltage, slow control and monitoring, gas system, software etc. INO Collaboration Meeting, VECC/SINP, Kolkata

9. Summary • Two proposed schemes • FPGA based • Non-FPGA based • Both are technically feasible • Time available for implementation is the decisive factor • Some concerns on this issue for the FPGA approach _ Mixed scheme approach INO Collaboration Meeting, VECC/SINP, Kolkata

10. Action plan for prototype • Design of front-end electronics • Detailed design of the DAQ system • Identify sub-tasks, assign responsibilities, work in parallel • New materials, equipment required, place orders • Preparing existing hardware • Crates, controllers, TDCs, scalers etc. • Prototyping, PCB designs etc • Debugging and testing • Integration issues INO Collaboration Meeting, VECC/SINP, Kolkata

11. Other important issues • Setting up design infrastructure • Initiation of future work • BARC’s ASIC programme • Identifying, funding, working together on areas of common interest • Long time scales, needs long lead times • Existing other spin offs for this activity INO Collaboration Meeting, VECC/SINP, Kolkata

12. And finally …. • Weekly meetings of eTRIDAS team • Monthly reviews • A workshop at an appropriate time • Minutes on INO official web site • Feedback to • bsn@tifr.res.in INO Collaboration Meeting, VECC/SINP, Kolkata
