Dear Gerard,

I see what you are concerning. 

We will update the plots on the tube parts and the constraints soon. Thanks a lot for pointing this out.

Cheers,

Yi

Dear Yi,
        I think I remain most curious as to what happens with the cooling tubes right
outside the wedge structure/ If there are connections near there, it will
severely impact the possibilities for T-board in this scheme. It would seem so,
anyway.
        I hope that we are not making the problem too difficult... To be specific, if
the mounting ring OD is much less than it might be (given external constraints),
that could be so. I wish we had these external constraints also on same drawing.
        Sincerely,

                Gerard
