TRIDAS strategies
• Test stand for detector R & D
• Instrumentation for prototype detector
• R & D and prototyping for full scale detector
March 31 - April 2, 2003
INO Collaboration Meeting, VECC/SINP, Kolkata
4
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

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.

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

7
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 subsystems such as VME hardware design, trigger,
high voltage, slow control and monitoring, gas
system, software etc.

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

9
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
10
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
