Hi Yuri,

We should include Jim and Tim in these discussion. Tim has RDO boards in the lab and we can check weights and sizes, and the teststand can probably be used to see how the RDOs are positioned.
THE FFE are not exactly at the same position as the OLD but shifted by a small amount (includes the holes for the FFEEs)

Hello Tonko, during yesterday ETOF meeting, it was a question about
the material budget before ETOF.

I have found that we have old description of geometry in GEANT for the
electronics readout , done in 2005 mainly for ECAL.

This description has not been updated with iTPC.

The question is : Do you have any drawings for the iTPC electronics
assembly ?

I believe the main difference is adding 2 more RDOs.

For ETOF it is necessary to update this geometry.
