Kuraray Fiber tests
The following fibers from Kuraray have been tested for light output with a Sr90 source.
- BLUE
- 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
- 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
- GREEN
- 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
- BCF20 individualy packed labled Set2 1/8 #5
This fiber is not very strait after about 100cm it starts to be wobbly.
position #photo-electrons ============================= 192cm 1.74 +/- 0.01 100cm 2.18 +/- 0.02 => Attenuation length L = 443 cm
- GREEN
- BCF20 individualy packed labled Set2 3/8 #7
This fiber is not very strait after about 100cm it starts to be wobbly.
position #photo-electrons ============================= 193cm 1.70 +/- 0.01 100cm 2.13 +/- 0.03 56cm 2.64 +/- 0.01 => Attenuation length L = 412 cm Attenuation length L = 311 cm
- GREEN
- BCF20 labeled: #620-MC-37 101796/18580 12/07/07 received in Dec. 2007
position #photo-electrons ============================= 100cm 0.88 +/- 0.02 59cm 1.36 +/- 0.04 59cm 1.32 +/- 0.03 193cm 0.31 +/- 0.01 => Attenuation length L = 97.5 cm Attenuation length L = 91.5 cm
