Back flange

• 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.
