Dear Pat, Alessandro and Stephen,

Sorry for my slow response again.
I looked into Alessandro's table v3 about Harness split.

I noticed there are two types of materials as you see below:
------------------------------------------------------------
Type-1              N1    N2    N3       N4      N5     N6
Permanent Clamp   1.870  1.840  2.175   2.185  2.190  2.650 
Z0 Interconnect   0.385  0.000  0.000   0.000  0.000  0.000 
Z6 Interconnect   0.000  0.000  0.000   0.000  0.000  0.440 
Interface PCB     1.434  1.434  1.434   1.434  1.434  1.434 
Connectors        0.671  0.671  0.671   0.671  0.671  0.671 
SUB TOTAL         4.360  3.945  4.280   4.290  4.295  5.195 
    
Type-2
Fibres on         0.223  0.445  0.655   0.921  1.071  0.345 
Power tape        1.014  2.029  2.984   4.197  4.877  1.572 
SUB TOTAL         1.236  2.475  3.639   5.118  5.948  1.917 
Length           12.364 12.374 12.130  12.795 11.895  3.195
Weight/length     0.100  0.200  0.300   0.400  0.500  0.600 
ratio to N1       1.000  2.000  3.000   4.000  5.000  6.000 
-------------------------------------------------------------
Type-2 can be adopted to the current power-tape volumes. 
Type-1 is constant along z. Therefore I propose to add one
straight volume from end to end just above the current 
power-tapes for Type-1. 

I have drawn the proposed volume in the drawings of 
  http://atlas.kek.jp/si-soft/geometry/rphiView-B3lowerB.pdf
  http://atlas.kek.jp/si-soft/geometry/rzView-B3(1)B.pdf
etc. Under this propossal, all power-tape strips have the
same density and composition, and the new volume (I call it
Harness) to be added is only one per raw (ski). If this is
acceptave, I will specify the location and sizes, while
Alesanndro makes the new Excel table accordingly.

About another issue, the size of dogleg, please take a look
of the drawing attached to this mail. I cannot make it
longer without crashing into the cooling pipe. Thus I would
like to stay with current volume for dogleg. Anyway the
to-be-extended part of the logleg is rather light 
comparatively, so I think no serious problem with current 
size. Hope you understand the situation.

best regards,
 
Taka

Dear Pat,

  Thanks for doing this. One thought: is it really  
necessary to have a
  different composition for each volume? I rather think this 
is an
  unnecessary complication, and that it would be adequate 
the use the
  average composition for all volumes, and I propose to do 
this. I can
  adjust the density for each volume.  

A.T.: From the table T1-T6 in 'harnessSplit' I see that the 
% of one
composite can differ up to ~12%, see for example Peek, 
however if this
makes the implementation in GeoModel too complicated I am 
happy if you
use the weighted mean under 'TOT' in row 172 
in 'HarnessSplit' sheet.

Cheers,
Alessandro
