Re: BCAL test



Thanks Zisis. We will talk more next week. See you then.

Hi Tim:

the fibers are pretty robust.  Short of eating them or trying to coil them too tightly, they can weather quite a bit.  Bending radius is safely set at 20x the fiber radius according to some literature I have seen, but I haven't tested this.  We never coil them that tightly.  Our coils are 15-20cm in radius usually.  The  fibers should not be exposed to light, primarily UV from fluorescent lights, although some incandescent lights should be watched.  When we work with them we do so in rooms with special UV-absorbing filters.  Finally, I can't recall the safe temperature range, but it must be pretty broad, and I don't believe this is an issue for shipping or handling (unless it is outside in Regina in January at -40 C).

See you next week at JLab.

Cheers, Zisis...

Hi Zisis,
I am interested in the robustness of the scifi fibers used in the BCAL. Was the section tested here at JLAB handled in any specific way? Is there a concern that the fibers could crack during shipping or temperature changes?

Thanks,
