To do list production organization and commitments RPC upgrade project G. Aielli - INFN meeting for Phase-2 To do list production organization and commitments

Project principal items Build 272 new RPC triplets to be installed in the BI region (and relative services) to increase the system redundancy and to cover ~27% acceptance hole Retrofit 32 BOL units and 16 BML-G units in the extreme eta regions, to reinforce these critical regions non fully recoverable with just the BI Replace the readout electronics (800 PADs) of the present system with a new ons compatible with the Phase-2 DAQ latency and better fit for the RPC performance  Riccardo Replace the power system with back compatibility G. Aielli - INFN meeting for Phase-2

RPCs are made of…. The new RPCs are triplets: Three fully independent singlets in a mechanical structure equipped with services Each singlet is an independent faraday cage containing a 2D readout detector equipped with a TDC per channel. It contains: One gas gap Two orthogonal readout strip systems Serial cables to connect TDCs to DCTs Each readout panel is made of A strip panel Frontend and termination boards integrated in the panel Readout panels of the same type are used for the BM-BO retrofitting G.

RPCs relates systems and services Control and Power system, made of: DCS infrastructure (PCs mainframes and branch controllers) Power crates and modules (primary power, HV, LV, Vth, Monitoring) Power and monitoring cables Sensors (T, P, RH, flow) Gas system, including: Retrofitting of the present gas rack 2-3 additional racks to increase the vertical granularity of the distribution and to host 48 new lines serving the BI Local distribution on chamber and flow sensors for monitoring G.
