  17. Current status • RPC detector R&D concluded quite a while ago. The RPC stacks are being used even for some physics studies. • Scaling up and industrial adaptation of lab technology – by an industry, is almost complete. • Extensive vendor development for material fabrication, process development, design of SPMs and for large scale production of RPCs. • Ready for engineering module. • Tenders for RPC production for engineering module are about to be floated. • Further fine-tuning of chamber design, operating parameters and maintenance related practices will continue.
