ltbuenerd_at_lpsc.in2p3.frgt Dear Dr. Buenerd, . gt
Here is a reminder gt - Accuracy of transverse
dimensions 113-0.2 mm gt - Accuracy of thickness
for different tiles -0.5 mm gt - Thickness
spread over one tile -0.3 mm gt - Tiles cutting
with dedicated dimensions according to drawings
(not gt mandatory). gt - Refractive index for
different tiles n1.050-0.001 (1.03 backup
solution) gt - Light scattering length more 45 mm
at 400 nm In the e-mail we send Mr. Mori on Oct.
8th, I wrote that we guarantee the transparency
82 for 1.03 and 75 for 1.05. You must have
heard this number. However, we may not be able to
satisfy some numbers you wrote here. Please
kindly check the samples and the data we send. I
hope you do not mean these numbers for guarantee.
We will surely produce aerogels in the same
process as the test production. So, products will
be similar to the samples of test production.
And, as I already told you, we can cut the tiles.
Please check the e-mail I send you on Oct. 15th
to ensure the difference from your drawings.

lthkishi_at_rda.mew.co.jpgt Dear Dr Kishimoto, ..... In
case your offer would be selected to be the
approved one, we need a Minimal guarantee that
the product will comply with our requirements.
To this purpose, we need more than the
qualitative statement from your previous mail on
the issue (enclosed below), since we do mean
these numbers must be guaranteed.Could you
please let me know whether you can match the
required features for the tiles to be supplied by
you gtgt - Accuracy of transverse dimensions -0.2
mm gtgt - Tolerable thickness difference from tile
to tile -0.5 mm gtgt - Thickness spread over one
tile -0.3 mm gtgt - Tiles cutting with dedicated
dimensions according to drawings gtgt - Refractive
index for different tiles n1.050-0.001 (1.03
backup) gtgt - Light scattering length more 45 mm
at 400 nm gt In the e-mail we send Mr. Mori on
Oct. 8th, I wrote that we guarantee gt
transparency 82 for 1.03 and 75 for 1.05. You
must have heard this gt number. However, we may
not be able to satisfy some numbers you wrote gt
here. Please kindly check the samples and the
data we send. I hope you gt do not mean these

184805 0900 ToMichel Bu?erd
ltbuenerd_at_lpsc.in2p3.frgt Dear Dr.
Buenerd, Unfortunately, we can not guarantee
your numbers. The reasons are 1) We can not
achieve some numbers. For example, the standerd
deviation of X is 0.269, but your requirement
is -0.2 mm. 2) There is a possibility to have
misunderstnding. Especially, in the expression
of cutting, we can not guarantee if the drawing
is not changed. Please check e-mail Oct. 15th
again. 3) The languages are different. We can
not guarantee the "Light scattering length",
because the method is different from yours.
This also might occur misunderstanding. We can
discuss a guarantee if you change the numbers
wider to match the result of our test production
(to make it possible) and change some
expressions (not to make misunderstanding). If
that is impossible, we have to give up your
order... I look forward to hearing a positive
reply from you. Best regards, Hirotsugu Kishimoto

• Matsushita
  Summary
• Optical prop. not very good (--)
• Hydrophobic ()
• High fragility (bad prospects for handling 4360
  tiles) (--)
• Thinner tiles than required _ stacking of tiles
  (-)
• Stack exceed allowed thickness(-)
• Clarity not measured by provider (-)
  who/where/when ?
• No stated guarantee on the quality of the
  product, so far. (-)
• Buy more of them and choose the good one
  measuring ourselves.
• Early delivery (but 3 times more tiles _gt3 full
  months of work)
• Novosibirsk
• The good optical properties selected at the
  previous meeting ()
• Hydrophilic (a handicap, but controllable) (-)
• Good mechanical robustness () only 100
  tiles to be handled
• Appropriate thickness (30mm or less) (), with
  some spread (-)
• Guarantee commitments provided (contract) ()
• Clarity measured by provider ()
• All different size are cut by the provider (edge
  tiles too)

Conclusion
For all the previous reasons, We believe the best
choice for the AMS RICH is the Novosibirsk 1.05
product. With a final optimization we have
choosen 27 mm thickness. (number of produced
photons\ scattering) A sample of 4 of them will
arrive this week , after accurate tests if result
is OK we are in favor to proceed to buy all of
them.

Aerogel umidity control

• To avoid any humidity contamination we seal the
• container and flush dry air or a neutral gas
  like pure N from time to time. (to keep humidity
  below 50 )
• Both in and out hole are controlled by valves and
  
• filters ,to avoid water in and aerogel
  particle out.
• The out valves automatically open at launch
  allowing depressurization.
