Pierluigi Paolucci - I.N.F.N. Naples Conclusions…….. I.N.F.N. Naples The reduced schema (80 boards  one HV channel per chamber) has been chosen for the HV system in order to: Keep the DT-RPC ground schema (crucial point); Have independent voltage for every chamber. The HV tender has been assigned to the CAEN: HV board: 3500 € (2003)  3500 €; EASY crate: 1000 € (2003)  950 €; Branch Ctrl: 1000 € (2003)  850 €; SY1527: 10000 € (2003)  8500 €; The cost of the HV is 500 K€ extra cost of 50 K€ The LV PS costs are known: No reductions The cost of the LV is 250 K€ extra cost of 105 K€ The cost of the DCS is 110 K€ extra cost of 67 K€ The cost of the DCS system is reasonable for a detector based on: more than 1000 gas gaps, 1200 HV-LV channels and about 80K electronic channel 11/17/2018 Pierluigi Paolucci - I.N.F.N.
