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
March 31 - April 2, 2003
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. INO Collaboration Meeting, VECC/SINP, Kolkata
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
March 31 - April 2, 2003
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
March 31 - April 2, 2003
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
