How many prototype planes strips?

• Each plane is the equivalent of 86 strips that
  are 3.6 m long. Each strip has a mass of 1.52 kg
  or 3.3 lbs.
• The weight of a plane (86 strips) is 131 kg or
  288 lbs. Order 15 extra scintillator 100
  strips per plane or 330 lbs (152kg).
• 3 u 3 v to over-constrain a straight line 6
  planes one spare to use for resolving multi-hit
  ambiguities one to learn the construction
  technique. gt 8 planes.
• Total scintillator is 2,341 lbs (1.17T) or 700
  strips or 1.064 Tonnes.
• Scintillator Cost - MINOS paid 10/kg or
  10K/tonne. Assume a 50 addl cost for a small
  order
• 
  16K

Fiber quantities and costs

• WLS Fiber
• Buy enough to instrument every strip 100
  strips3.6m/strip 360 m times 8 planes (one to
  learn on).
• gt 2.88km
• Kuraray quote of 3.29m gt 9,475 plus shipping
  duty
• so add 1,500, which brings the total to
  11K WLS
• Clear Fiber
• From engineering drawing
• Short near strips 214.6 m 97m
• Full strips 43(4.6m 2.3m) 297m
• Short far strips 214.3m 90m
• Total
  484m gt 550m times 8 planes
• 
  4,400 m
• Clear cost 4.4km3.11K/km 13.7K 1.5K

• Plastic sheets for fiber routes
• 10/sqft acrylic or 6/sqft Lexan
• (6-10/sqft)110sqft/sheet8 sheets 5.3-9.0K
• Machining of plastic sheets
• 20 hrs of programming40/hr 0.8K
• 60 hrs Gerber routing40/hr 2.4K
• Total machining of plastic sheets
  3.2K
