• Remove M1 station

• Preserve the present MWPCs and their front-end electronics in M2-M5 stations– to improve the detector performances at high luminosity, the replacement of the

innermost chambers of M2 and M3 with high granularity detectors is under study

• Maintain the present Intermediate Board (IB) system (with the exception of M5R4) to generate the logical channels

• Use new Off Detector Electronics (nODE) boards for an efficient readout @ 40 MHz– Back compatible with the current off detector electronics and crates

– Based on new custom ASIC (nSYNC), GBT and versatile link components

• Replace the Service Board (SB) system– Efficient chamber pulsing (nPDM) and control (nSB) via GBT and versatile link

components

• Based on Maraton System– Primary rectifiers and Remote Controllers in a safe environment (behind the wall)

– Long cables + patch panels (in a fixed position) + movable cable chain

– Maraton Power boxes on each rack of the muon towers

• Front-end electronics (FEE) powering scheme– Maraton power box + patch panel (rack) + linear regulator (on detector)

• Each FEE power box has 12 channels @ 2..7V/55A (330 W maximum)

– 8 FEE power boxes installed (2 for M1, 4 for M2-M3, 2 for M4-M5)• Present maximum power consumption per power box ~ 1kW

• Present maximum power (current) consumption per channel – ~ 172 W (43A) in M4-M5

– ~ 130 W (34A) in M2-M3

• Upgraded power system will use the current Maraton System components and cables

– M1 will be removed • All system components can be used as spares

– M2-M5 FEE power boxes• No changes foreseen

– 6 FEE power boxes + 6 patch panels required (in the racks of the muon towers -UXB)

– Enough margin to handle a potential power increase with the rate

• In case of innermost M2-M3 chambers replacement 2 more power boxes should be foreseen

– M2-M5 off detector electronics power boxes• No changes foreseen

– 8 power boxes required (in the racks of the muon towers- UXB)

– The new nODE, nSB and nPDM boards will use the current rack power lines and they will generate internally the new required voltages

– Current power is enough

» A local (rack level) power line reshuffling for the high power channels could be needed

– 14 (+2) AD/DC primary rectifiers in 4 power boxes (in the rack behind the wall – UXA-B)• No changes foreseen

– 14 RCM (+2) controller modules in 2 VME like crates (in the rack behind the wall – UXA-B)• No changes foreseen

– Current cabling can be maintained• In case of innermost M2-M3 chambers replacement 2 more power and control cables should be

installed

• No change required in crates and racks on the muon towers

• No major change foresees for LV power system– Re-use present Maraton components for frond-end electronics

and off detector electronics power supply– Existing electrical power seems enough– Present cabling could be maintained– 2 new power boxes and cables should be installed in case of

innermost M2-M3 chambers replacement

• No change foresees for HV power system

• New multi-ribbons cables required for DAQ and TFC/ECS links– Try to re-use single ribbon cables from rack patch panels to

cavern patch panels
