7. ME0 Power : Possible Granularity Each single detector will consist – 3072 readout channels – strips running one directional in φ – 24 VFAT3 chips – 1 optical-hybrid based on GBTs One ME0 super-module wedge will consist 6 times the single detector. – 18432 readout channels – strips running one directional in φ – 144 VFAT3 chips – 6 optical-hybrids based on GBTs

LV Power Table and LV Cables Package ME0 – single detectorME0 complete super- module Per Endcap 24 VFAT3 FEBs – 24W144 VFAT3 FEBs – 144W 1 Optical hybrid – 40W6 Optical hybrids – 240W Total LV power = 64W Total LV power = 384W 384x12 = 4368 W Modular Structure of ME0 permits easy maintenance and operation of all the electronics The LV power granularity should follow the same concept. It will secure: Flexibility of switch on/off part of the super-module Secure the LV current monitoring on single detector level. Dealing with “low” currents per cable. The LV power cable package could be: 6 cables for the VFATs 8A@3V 6 cables for the optical hybrids 14A@3V 22A@3V 8A@3V 14A@3V

9. Fibers – Possible Layout Per single detector we have 4 versatile optical links with 8 fibers to the uTCA GEB in total Per super-module we will have 24 versatile optical links with 192 fibers to the uTCA GEB

10. HV Powering It will be based on Multichannel system able to measure the HV currents through the GEM foils. GEM tops GEM bottom

11. Cable Package for the ME0 super- module - Wedge 12 LV cables – (6 x 14A@3V) + (6 x 8A@3V) 192 Fibers (24 versatile links to uTCA GEB) 6 HV Multi-core cables
