Dear Jason and Jim, thank you for the drawings.

 

One question: Can I assume that holes marked on the left side of the fist drawing (TPC350-E-1) as  “2X”are set screw to support RDO ?

Subject: Re: [[Star-tpc-l] ] new RDO in STAR iTPC geometry

Dear TPC Experts,

 

Enclosed is an up to date diagram for the iTPC sectors.   The comment box in the upper right hand corner indicates that the drawing includes modifications for the Grid Leak Walls, and slots for the electronics shifted to their new positions.

 

P.S. Many thanks to Jason Farrell for creating this drawing for us.  He did an outstanding job on a very fast timescale.

 

Cheers,
Jim

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)

best Flemming
