• 20-degrees/chamber in phi, 2-chamber units offset in phi degrees in successive layers– Assures 4 or more hits at all f ,
given the dead space between abutting chambers
• Absorbers removed from previous version
• Need simulations to evaluate geometry
• Weight of each 20 x 18degree 6 layer wedge 60x6 = 360 kg
• Weight of ME0 per endcap360x12= 4320 kg

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 PackageME0 – single detector ME0 complete super-
modulePer Endcap
24 VFAT3 FEBs – 24W 144 VFAT3 FEBs – 144W
1 Optical hybrid – 40W 6 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

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