  1. Indigenous R & D efforts for HEP detectorsGlass Resistive Plate Chambers for INO experiment Proposer: B.Satyanarayana Mentor: Prof Naba K Mondal Department of High Energy Physics, TIFR, Mumbai, 400005

  2. What is the need? • Detectors form the core of scientific research! • What is ‘discoverable’ in an experiment is often limited by capabilities of the employed detector • Why do we need indigenous development? • Need for large and sustained efforts • Rich experience of various detector development activities for KGF, DZERO, CMS experiments • Now, the proposed Indian-based Neutrino Observatory (INO) is looking for a new detector! DAE Vision 2020, Subtopic 3.8, May 3-4, 2004

  3. The proposed INO detector • RPC dimension: 3m X 2m • No of chambers: 11K • No of channels: 220K • No of TDC channels: 3K Magnetised iron calorimeter Iron 140 layers RPC 35KTons DAE Vision 2020, Subtopic 3.8, May 3-4, 2004

  4. Why RPCs? • Rugged, cheap and easy to produce large area cells • Good timing, counting rate, spatial resolution, large signals • Can take roles of tracking, timing, particle identification and (even) calorimeter detectors • Being used or planned for many HEP, Cosmic ray, astroparticle physics experiments: • All four LHC experiments, Belle, Babar, HARP, EAS-TOP • Choice of designs, modes of operation, gases etc DAE Vision 2020, Subtopic 3.8, May 3-4, 2004

  5. A typical RPC construction DAE Vision 2020, Subtopic 3.8, May 3-4, 2004

  6. RPC R & D infrastructure at TIFR DAE Vision 2020, Subtopic 3.8, May 3-4, 2004

  7. A few of our preliminary results DAE Vision 2020, Subtopic 3.8, May 3-4, 2004

  8. Proposal for new work • Double-gap, multi-gap and Hybrid designs • Avalanche versus streamer modes of operation • Gas mixture studies and optimization • MIP efficiency issues • Improvement of time resolution • Special RPCs for finer spatial resolution • The all important ageing concerns DAE Vision 2020, Subtopic 3.8, May 3-4, 2004

  9. Proposed plan for new work • Gases, mixing, circulation and monitoring systems • Industrial help for resistive coats on electrodes etc. • In-house development of electronics and DAQ • Simulation studies – Process, Device and Detector • Meeting INO design requirements in the process • RPC deployments beyond INO • Possible spinoffs … DAE Vision 2020, Subtopic 3.8, May 3-4, 2004

  10. A proposed spinoff • Positron Emission Tomography (PET) • A radiotracer imaging technique using positron emitting radio nuclides • Applications include: • Early detection of cancer • Neurophysiological studies • Quantification of brain functions • Natural advantages in case of RPC • Intrinsic layered structure (~100 layers) • Simple and economic construction • Time-of-Flight capability • Considerably lower radiation levels for whole-body PET DAE Vision 2020, Subtopic 3.8, May 3-4, 2004
