Alexander,

thank you for filling the form and the comments, I agree with them, but nevertheless it would be so nice to once get something positive, 

to define patch panels or HV distribution boards and so on one needs first to know what one needs, this is what we are collecting and then we optimize based on the info.

This is not even version 0, and yes absolutely things depend on the readout electronics choice no doubt. 

But as you saw from the talk yesterday evening we will also work on this in parallel.

It would be wonderful if all would be know but it is not.

It is obvious from what we have right now, we need to use HV distribution boards, but the question where they can be located is also not easy.

Cheers elke

  Dear Elke,

  I populated a "services wish list" backbone for pfRICH, and we will now proceed with the TBD items:

ePIC.Interface Control Document for Services.112022.xlsx

 I was wondering though, what are the sanity boundaries for these numbers. I mean at which point one should start worrying about a sheer quantity of the HV/LV/fiber connections, and grouping them into HV dividers, LV distribution panels and ASIC backplane concentrators?

  Another question is: which electronics should we take as a reference? Apparently almost everything in this table will depend on this choice, with numbers being different potentially by a factor of 1-10, easily (channel count per ASIC, mW/ch, etc).  

  Regards,

    Alexander.
