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

4
Groove

• Shape
• Sigma
• Straight
• Others
• Depth
• 1, 1.5 and 2 mm

5
Fiber

• Type
• Bicron, Kurraray
• Diameter
• 0.7 0.9 mm
• Shape
• circular and square
• Contact
• glue, air

Are we interested in red fibers?

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)

7
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
