Fiber Spectra - Regina
From GlueXWiki
Images of the setup for measuring the spectra of scintillating fibres using an Ocean Optics fibre optic spectrometer, a UV (380nm) LED and some clamps.
1. spectrometer, LED, jig and fibre
2. same, but from the back
3. darkened room, UV LED on a BCF-12 fibre
4. the entire apparatus with the fibre clamped at the near end
5. close up of the fibre and jig
6. notice there is no room for fibre movement
7. overhead view
8. BCF-60,20,12
9. BCF-60,20,12
10. gluing on SMA connectors
The spectra of BCF-60, BCF-20 and BCF-12 from distances of 15cm (maximum amplitude) up to 190cm (minimum amplitude). There are little or no jumps or overlaps indicating good transmission and the fibres were clean.
BCF-60: slow green
BCF-20: fast green
BCF-12: blue
