Dave,
As a guide....
In answer to 5) the 'current' scheme has 29 '100' channel units and 11 '75'
channel units per Dee. This equates to 87 long cooling bars (100 ch) and 33
short cooling bars (75 ch) per Dee. There is also a long cooling bar
required for the token ring link board per sector of an end cap (between
9-10 depending on design).
Putting the numbers together results in a total of 368 long bars and 132
short bars - without spares.
All the above is 'based' on the current layout which is still under design.
Dave, I should await Tony's response as he can verify and comment his
thoughts on the current layout.

Regards
	John

 I spoke with Marco Paganoni yesterday concerning the cooling bars.

 1) Castings

    They are prepared to help - there should be no problems for the '4'
    trigger tower bar lengths if the same barrel design is used.
    If the '3' is simply a shorter version of the '4', this should
    be possible, but would require its own mould.

    Approx costs for the castings:
        8 euro/bar     aluminium material
        8    "         stainless steel pipe
        14   "         inserts to position tube in mould
   Total 30 euro/bar = 60k euro for barrel = 90k euro after VAT &
contingency.

   They expect to use only one mould for all of the '4's includuing the EE
'4's.
   A mould for the '3' is ~ 5k euro.

   The endcap is ~25% of the barrel => ~ 22.5k euro for all bars + 5k mould
   ~ 27.5k euro for all EE castings (~20k pounds including VAT).

 2) TVA(VAT): Marco - are you not exempt for VAT(TVA) for goods for export
to CERN?

 3) Final machining

    For the barrel Marco estimates 200k euro for machining (50 micron
precision)
    =>  ~ 50k euro for the endcaps (~36k pounds).

 4) Total for all EE finished bars, ~ 56k pounds.

 5) Tony/John - can you send the number of '4's and '3's for the EE to me
and Marco
    asap ?

    Can we tell Marco to go ahead for production, at least for the '4's?

   Thanks, Dave.

                              *************************

 Addendum 1) Marco is seeking a non-destructive ultrasound testing system to
check
             the infill of aluminium within the moulds.
             Do we have any expertise at RAL, or contacts outside?
             *** email to me and Marco asap if so.

          2) N.B. The bars in module 1 are different to those in modules 2,3
and 4
             on the barrel - which are needed on EE?

             Bar dwgs on EDMS at CMSEBSMM0192 (mods 2-4), CMSEBSMM0181 (mod
1).

          3) The bars are welded/soldered to the inlet and outlet cooling
pipes/manifolds
             both internally and externally - this is a very precise
operation.
             We need to meet with the technical experts from Italy to
discuss
             making the EE assemblies of bars/manifolds.

             Do we need bars/manifolds made up already for E0'???
