Vishnu V. Zutshi
               Introduction
 Based on my conversations with Sasha and
  Manuel
 We already have intimations of tile-fiber
  system optimization
 Need to systematically carry out further
  measurements to codify this knowledge
 This is a first attempt to compile these tests
  so that we can plan appropriately
                  Scintillator
   Type:
       Bicron
       Eljen
       Extruded
• Shape:
     square and hexagonal
 Thickness
       3, 4 and 5 mm
                    Groove
   Shape:
         Sigma
         Straight
         Others
   Depth:
         1, 1.5 and 2 mm
                        Fiber
   Type:




                                  Are we interested in red fibers?
         Bicron, Kurraray
   Diameter:
            0.7 – 0.9 mm
   Shape:
            circular and square
   Contact:
            glue, air ……
       A suggested course…..
   Find optimum groove depth:
      1 mm depth (3 cells)
     +1.5 mm depth (3 cells)
     +2.0 mm depth (3 cells)
     +2.5 mm depth (3 cells)

    (groove shape is optional but preferably straight)
       A suggested course ….
   Using optimum groove depth:
      5mm hexagonal with sigma groove (5 cells)
     +5mm square with sigma groove (5 cells)
     +5mm --- with ‘other’ groove (5 cells)
     +4mm --- with --- groove (5 cells)
     +3mm --- with --- groove (5 cells)
      A suggested course …
 Begin fiber studies (course less clear as it
  most probably involves ordering)
 Within sample spread is an issue in this
  study (do we wrap instead of paint ?)
 We most likely also want to get an idea of
  the light output for 6 and 12 cm2 cells
 Whatever I have left out ……
