Indigenous R & D efforts for HEP detectors Glass Resistive Plate Chambers for INO experiment: 

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

What is the need?: 

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!

The proposed INO detector: 

The proposed INO detector Magnetised iron calorimeter Iron RPC 140 layers RPC dimension: 3m X 2m No of chambers: 11K No of channels: 220K No of TDC channels: 3K 35KTons

Why RPCs?: 

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
