Kuraray Fiber tests

The following fibers from Kuraray have been tested for light output with a Sr90 source.

  • BLUE
  1. 81 MC lot:0801/103
  position     #photo-electrons
  =============================
   165cm        3.7  +/- 0.08
    65cm        5.1  +/- 0.2
   194cm        3.2  +/- 0.05 

  => Attenuation length L = 300cm
  1. 78 MC lot:0801/104
  position     #photo-electrons
  =============================
   194cm         3.9 +/- 0.07
    94cm         5.97+/- 0.27 
    61cm         6.99+/- 0.31

  => Attenuation length L = 230cm
  • GEEN
  1. 3HF MC lot:0801/105
  position     #photo-electrons
  =============================
    65cm        2.3  +/- 0.03
   165cm        1.95 +/- 0.01
    61cm        2.3  +/- 0.03
   161cm        1.95 +/- 0.02

  => Attenuation length L = 605.8 cm


Saint Gobain Fiber tests

The following fibers from Saint Gobain (aka Bicron) have been tested for light output with a Sr90 source.

  • GREEN
  1. BCF20 Set2 1/8 #5
    This fiber is not very strait after about 100cm it starts to be wobbly.
      position     #photo-electrons
<br> =============================<br> 192cm 1.74 +/- 0.01<br> 100cm 2.17 +/- 0.02<br><br> => Attenuation length L = 447 cm
