Spectral and Characteristic Data
This page shows emission spectra and main characteristics (emission peak, decay time, decay length, etc.) of scintillation fiber/wavelength conversion fiber. Please use this information as a reference when comparing grades and evaluating options.
Scintillating Fiber
This basic type emits light when exposed to radiation and is used for detection. Luminescence peak/attenuation time/attenuation length can be compared.
| Description | Emission | Decay time NS21 | Att.Leng. [m] | Light yield [photon/MeV] | Characteristics | |
|---|---|---|---|---|---|---|
| Color | Peak [nm] | |||||
| SCSF-78 | blue | 450 | 2.8 | >4.0 | ≳14,000 | Long Att. Length and High Light Yield |
| SCSF-81 | blue | 437 | 2.4 | >3.5 | ≳11,000 | Long Att. Length |
| SCSF-3HF (1500) | green | 530 | 7 | >4.5 | ≳8,000 | 3HF formulation for Radiation Hardness |

Attenuation Length Measurement Method
Attenuation lengths are regularly measured for all produced products using 3 m fiber samples.
The decay curves in the figure (for example) are approximated by the single exponential formula I(x) = I₀ exp(-x/λ) except at very short distances. The attenuation length λ is calculated using data between x = 100 cm and x = 300 cm.
Wavelength Converting Fiber
This type converts the emission wavelength to increase light-receiving efficiency. Absorption and emission peaks and attenuation lengths can be compared.
