For package of 6

  • 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 18

Me0 power possible granularity
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 wedgewill consist 6 times the single detector.

    • 18432 readout channels – strips running one directional in φ

    • 144 VFAT3 chips

    • 6 optical-hybrids based on GBTs

  • 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.


Fibers possible layout
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
HV Powering

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