Dear Stephen,

Thank you so much for your e-mail about SCT materials. I apologize you
that I had no chnace to discuss with you about details and recent
progresses in Japan.

I am coming to the ATLAS Overview week at Paris for first 3 days. I saw
your name in the participant list. Can we meet and discuss during the
overview week?

Essentially, our program is based on information provided by your Web page
for SCT material budget,
  http://hepunx.rl.ac.uk/atlasuk/sct/engineer/material/index.html
I used data from
     -Barrel Cylinders - Eric Perrin (11 Apr 05)
     -Barrel Cooling - Steve McMahon  (7 Sep 05)
     -Barrel Modules - Steve McMahon (4 Jul 05)
which you kindly uploaded to your web page, and additional information 
that Tony Weidberg gave to me on opto-harness.

I agree with your suggestion. I am looking forward to
meeting/discussing with you at Paris.

Taka
