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
